Module : Dtwinver.cpp
Purpose: Implementation of a comprehensive class to perform OS version detection
Created: PJN / 11-05-1996
History: PJN / 24-02-1997 A number of updates including support for NT 3.1,
single mode DOS in Windows 95 and better Windows
version detection under real mode DOS.
PJN / 13-09-1998 1. Added explicit support for Windows 98
2. Updated documentation to use HTML.
3. Minor update to the web page describing it.
PJN / 22-06-1999 1. UNICODE enabled the code.
2. Removed need for the dwOSVersionInfoSize variable
3. Added support for detecting Build Number of 95 and 98 from DOS code path.
4. Now ships as standard with VC 5 workspace files
5. Added explicit support for Windows 95 SP 1
6. Added explicit support for Windows 95 OSR 2
7. Added explicit support for Windows 98 Second Edition
8. Added explicit support for Windows 2000
9. Added explicit support for Windows CE
10. Added explicit support for Windows Terminal Server's
11. Added explicit support for NT Stand Alone Server's.
12. Added explicit support for NT Primary Domain Controller's
13. Added explicit support for NT Backup Domain Controller's
PJN / 23-07-1999 Tested out support for Windows 98 SE, minor changes required
PJN / 26-07-1999 Added explicit support for Windows 98 SP 1
PJN / 28-07-1999 1. Fixed a problem when application is build in non-huge/large
memory model in Win16
2. Added explicit support for returning NT and Win9x service pack information
from Win32 and Win16 code paths
3. Updated test program to not bother reporting on any info which does not
exist. e.g. if there is no service pack installed, then we don't bother
displaying any info about service packs
4. Added explicit support for NT Enterprise Edition
PJN / 30-06-2000 1. Added explicit support for Windows Millennium Edition
PJN / 29-01-2001 1. Added explicit support for Windows XP (Whistler) Personal
2. Added explicit support for Windows XP (Whistler) Professional
3. Added explicit support for Windows XP (Whistler) Server
4. Added explicit support for Windows XP (Whistler) Advanced Server
5. Added explicit support for Windows XP (Whistler) Datacenter
6. Added explicit support for Windows XP (Whistler) 64 bit (all flavors)
7. Made all the code into a C++ class called COSVersion
8. Rewrote all the generic thunk code to be easier to follow
9. Generic thunk code now uses CallProcEx32W
10. Added explicit support for BackOffice Small Business Edition
11. Added explicit support for Terminal Services
12. 16 bit code path now can determine ProductSuite and ProductType type
thro additional generic thunk code
13. Provided a 64 bit test binary and make batch file (make64.bat) for
those lucky enough to have an Itanium processor and a beta of 64 bit Windows XP (Whistler).
14. Provided a Embedded C++ workspace and X86 Release binary.
15. Updated copyright information
PJN / 10-02-2001 1. Updated function names etc following MS decision to call Whistler "Windows XP"
PJN / 10-10-2001 1. Added code to 32 bit code path to detect if we are being run under 64 bit Windows. Also
updated the sample app to distinguish between emulated 64 bit and underlying
64 bit.
2. Updated the sample app to call XP Server its proper name which will be "Windows.NET Server"
PJN / 13-12-2001 1. Major upgrade. Now 16 bit DOS path can return as much information as native Win32 code.
This is achieved by spawning off the Win32 utility WriteVer with a special command line option.
Please note that if you intend deploying Dtwinver then you must now ship the writever.exe file
in addition to linking in the Dtwinver code into your application. Also this utility needs
to be in the path or current directory when the Dtwinver code is executing. Thanks to Chaz Angell
for prompted me into finding a solution for this last major item missing in Dtwinver.
PJN / 30-12-2002 1. Provided an update CE workspace to work correctly in eMbedded Visual C++ v3. All build configurations
for eVC 3 have also been provided.
2. Optimized the usage of _tcscat and _tcscpy in the test app which comes with Dtwinver.cpp
3. OEM Info string and Platform Type string is now returned for CE code path
4. Fixed display of minor version number for example Windows .NET is version number v5.20 but
should be shown as 5.2 to be consistent with what the native ver command displays
5. Provided a new CE workspace to work correctly in eMbedded Visual C++ v4. All build configurations
for eVC 4 have also been provided.
PJN / 08-10-2002 1. Now uses OSVERSIONINFOEX it possible in the Win32 or Win64 code paths. This provides for
more reliably detection of Windows XP Home Edition.
2. Renamed the functions which detect Windows .NET Server 2003. Also updated the test code which
prints out these names
3. Provided explicit support for Windows .NET Web Server
4. Fixed a bug in the display of the minor OS version number on Windows .NET Server.
5. Made the project for WriteVer a VC 5 project instead of VC 6 which it was up until now.
6. Reworked the internal function WhichNTProduct to use a constant input string parameter
7. Added explicit support for Windows NT / 2000 / XP Embedded
8. Added explicit support for detecting Terminal Services in remote admin mode
PJN / 10-10-2002 1. Fixed a problem where on Windows XP, the test program will include the text "(Standard Edition)"
2. Added two variables to the OS_VERSION_INFO structure to report the minor service pack number
3. Removed the OS_VERSION_INFO structure from the global namespace
4. Removed all static member variables from the class
5. Added a member variable to the OS_VERSION_INFO to return the various "suites" installed
6. reduced the number of calls to WriteVer to 1 when called from dos code path.
7. Completely reworked the internal WhichNTProduct method
8. General tidy up of the header file
9. Completely reworked the ValidateProductSuite method
10. Now only 1 call is made to WhichNTProduct throughout a single call to COSVersion::GetVersion
11. Now only 1 call is made to ValidateProductSuite throughout a single call to COSVersion::GetVersion
12. Fixed an uninitialized variable problem in COSVersion::IsUnderlying64Bit
13. Changed "WhichNTProduct" method to "GetNTOSTypeFromRegistry"
14. Changed "ValidateProductSuite" method to "GetProductSuiteDetailsFromRegistry".
15. Now correctly reports on Terminal Services being in Remote Admin Mode on OS which do not
support calling GetVersionEx using an OSVERSIONINFOEX structure i.e any NT 4 install prior to SP6.
16. 16 bit Windows code path now reports as much NT information as the Win32 code path
17. Fixed a bug in COSVersion::GetInfoBySpawningWriteVer which was failing if it encountered
an empty CSD string. This was spotted on Windows .NET Server which since it is in beta still
(as of October 2002) does not have any service pack!.
PJN / 10-01-2003 1. Update to support MS deciding to change the name of their Whistler Server product. The product
will now be called "Windows Server 2003".
PJN / 30-01-2003 1. Added explicit support for detecting NT Service Pack 6a
PJN / 08-02-2003 1. Added explicit support for detecting Windows XP Service Pack 1a
2. Added support to determine the HAL on NT Kernels.
PJN / 12-02-2003 1. Fixed a compiler warning in GetNTServicePackFromRegistry which occurs when the code is compiled
with the Watcom compiler. Thanks to Christian Kaiser for reporting this.
PJN / 08-03-2003 1. Updated a comment in COSVersion::GetProductSuiteDetailsFromRegistry re NT Embedded.
2. A comment from John A. Vorchak: On NTe (NT Embedded) and XPE (XP Embedded), all of the versions
(of DTWinver) work just fine so long as the components to support them are included in the images,
which itself is kind of a crap shoot. I think that you would probably find that most images will
not support the DOS or Win16 versions however most will support the Win32. Many of the images that
folks build either do not include the DOS subsystem and some of them do not include Explorer, so it
really can't be said that all builds will support them however it is not difficult for a developer
to understand which version would work for them as they understand their target systems better than
anyone and at least one version would certainly work for almost all images.
As far as Win2k (Server Appliance Kit), I haven't done enough testing with that platform, nor do I
currently have any built images with the SAK to say positively or otherwise. More than likely you
would find no problems with the SAK images since they typically follow W2k much more than NTe or
XPE do.
Author: If you are writing for an embedded OS, then there is little use for DTWinver!!, since the
developer has very tight control over the runtime environment. Also if you do use DTWinver on an
embedded version of Windows, you will probably compile in the Dtwinver code rather than ship the
sample binaries I include in the Dtwinver download.
PJN / 09-04-2004 1. Removed a number of unreferenced variable warnings when you compile the code on on VS.NET 2003.
Thanks to Edward Livingston for reporting these issues.
2. Now includes support for Windows XP Media Center Edition. Please note that if you want to do
specific version checking of what version of Media Center you have installed then you should use
my CVersionInfo classes at http://www.naughter.com/versioninfo.html in conjunction with the following
information which I culled from http://www.mvps.org/marksxp/MediaCenter/2004/version.php which
describes the various version numbers of ehshell.exe in \Windows\ehome to the corresponding versions
of XP Media Center Edition.
Windows XP Media Center Edition: 2002 5.1.2600.1106 First released version of Windows Media Center
5.1.2600.1142 Highest released build of Media Center 2002
(provided via Q815487)
Windows XP Media Center Edition: 2004 5.1.2600.1217 Release build of Windows Media Center 2004
(upgrade over previous MCE 2002 build).
5.1.2600.1321 December 2003 Hotfix for Media Center 2004 version
(provided via Q830786)
5.1.2600.2096 Media Center Version included with Windows XP
Service Pack 2 Release Candidate 1. This version can
be installed over a current MCE 2002 or 2004 using
the Windows XP Service Pack 2 installer. If you have
any build between 1322 and 2095 assume this to be
a beta version.
3. Dtwinver now returns the processor architecture via a call to GetSystemInfo or GetNativeSystemInfo.
This is used to differentiate between 64 Bit Windows on Itanium and AMD64 processors.
4. Renamed the global preprocessor defines used by Dtwinver to use more unique names
5. Added make files and binaries for AMD64 processors
PJN / 26-06-2005 1. INTEL_PROCESSOR enum is now more correctly know as IA32 which means x86 32 bit.

IsWindowsServer2008. Thanks to Matt Fox for reporting this issue.
5. Added comprehensive support for Windows 2008 R2
6. Reworked the GetInfoBySpawningWriteVer method to work correctly on OSes which use UAC. The code now uses
_tempnam which places the temporary file in the "TMP" directory.
7. Fixed a bug in GetInfoBySpawningWriteVer where it incorrectly parsed the dwSuiteMask values.
8. Extended WriteVer and GetInfoBySpawningWriteVer to also update dwSuiteMask2

3. Added a IsHomeServerPremiumEditionInstalled method.
4. Fixed a bug handling PRODUCT_CLUSTER_SERVER_V ProductType
5. Fixed a bug handling PRODUCT_CLUSTER_SERVER ProductType
6. Fixed a typo in the name of IsSmallBusinessServerInstalled method
7. Added a IsWindowsCENET method.
8. Added a IsWindowsEmbeddedCompact method.
9. The sample app has been updated to differentiate between the various marketing names for CE i.e. Windows CE,
Windows CE .NET and Windows Embedded Compact. The code has also been verified to operate correctly on Windows Embedded
Compact using a OSDesign project on Visual Studio 2008 Professional, Windows Embedded Compact, a sub project which
builds DtWinVer for x86 CEPC and a VMWare image of Compact 7 running the DtWinVer binaries. Thanks to Mike Ryan for
prompting this update.
PJN / 02-07-2011 1. Updated to support Windows 8 and Windows Server 2012. These are the names which DtWinVer currently uses to refer
to the next client and server versions of Windows respectively. At the moment there is no official details from
Microsoft on what the product names will be, but DtWinVer will be updated following any announcements.
PJN / 17-09-2011 1. Updated the code to work correctly against the Windows 8 Developer Preview and Windows 8 Server Developer
Preview builds.
2. Updated code to refer to Windows codename "8" and Windows codename Server "8" instead of Windows 8 and Windows
Server 2012.
PJN / 28-04-2012 1. Updated copyright details.
2. My guess from last year was correct! Windows codename Server "8" will become Windows Server 2012. The code has been
updated to reflect this announcement from http://www.microsoft.com/en-us/news/Press/2012/Apr12/04-17MMSDay1PR.aspx.
3. Updated code to refer to Windows codename "8" as Windows 8 based on information from
http://windowsteamblog.com/windows/b/bloggingwindows/archive/2012/04/16/announcing-the-windows-8-editions.aspx.
4. Removed tests for Windows 8 (Home Basic), Windows 8 (Home Premium), Windows 8 (Ultimate) from code.

3. Updated the code to compile cleanly on VC 2012
PJN / 26-05-2013 1. Updated copyright details.
2. Now includes support for Windows 8.1 formerly known as Windows "Blue". I have also added code to support the
server version of "Blue" which for the moment I am calling Windows Server codename "Blue".
PJN / 07-06-2013 1. Updated all code references of Windows Server codename "Blue" to Windows Server 2012 R2.
PJN / 21-07-2013 1. Fixed some /analyze warnings reported by VS 2013 Preview.
2. The code now correctly handles the case where Windows 8.1 and Windows 2012 R2 lies about the real windows
version number. For details see http://msdn.microsoft.com/en-us/library/windows/desktop/dn302074(v=vs.85).aspx.
This change should also mean that correct OS details are returned when the code is run from a process in which
AppCompat version number shims are installed. Thanks to Christian Kaiser for reporting this issue.
3. All RegOpenKeyEx now requests the non virtualized key via the KEY_WOW64_64KEY value.
4. Reworked the WriteVer application to correctly compile under Unicode.
5. Win32s is now surfaced as a suite value.
6. Major rework and refactoring of all the DtWinver code base and test app. This rework should make it easy to
update the code going forward.
7. The suite details are now only reported after the underlying OS details in the test app.
8. The sample app now uses a larger stack buffer for displaying the OS details. This avoids any potential
stack overwrite issues when the number of suite mask values returned is large.
9. Fixed a bug in the generic thunking code path in GetProductInfo which resulted in the Win32 API of the same
name failing.
PJN / 14-04-2014 1. Updated copyright details
2. Updated code to compile cleanly using VS 2013
3. Updated code to report failure when compiled under Windows RT i.e. when the WINAPI_FAMILY preprocessor
value is anything other than WINAPI_FAMILY_DESKTOP_APP
4. Added support to detect Windows 8.1 / 2012 R2 Update
PJN / 01-10-2014 1. Updated code to support Windows 10 Technical Preview and Windows Server 10 Technical Preview.
PJN / 17-01-2015 1. Updated copyright details.
2. Fixed up the COSVersion::IsWindows2000AdvancedServer method to correctly distinguish between server and client OSes.
3. Fixed up the COSVersion::IsEnterpriseWindowsServer2003 method to correctly distinguish between server and client OSes.
4. Fixed up the COSVersion::IsEnterpriseWindowsServer2003R2 method to correctly distinguish between server and client OSes.
5. Fixed up the COSVersion::IsEnterpriseWindowsServer2008 method to correctly distinguish between server and client OSes.
6. Fixed up the COSVersion::IsEnterpriseWindowsServer2008R2 method to correctly distinguish between server and client OSes.
7. Fixed up the COSVersion::IsEnterpriseWindowsServer2012 method to correctly distinguish between server and client OSes.
8. Fixed up the COSVersion::IsEnterpriseWindowsServer2012R2 method to correctly distinguish between server and client OSes.
9. Fixed up the COSVersion::IsEnterpriseWindowsServer10 method to correctly distinguish between server and client OSes.
PJN / 29-04-2015 1. Updated the code to correctly handle / identify Windows 8.1 with Bing (aka CoreConnected). This applies to the
ProductInfo values: PRODUCT_CORE_ARM, PRODUCT_CORE_N, PRODUCT_CORE_COUNTRYSPECIFIC, PRODUCT_CORE_SINGLELANGUAGE &
PRODUCT_CORE. Thanks to Petr Stejskal for reporting this issue. The suite value that is used to identify this is
COSVERSION_SUITE2_CORECONNECTED and the method IsCoreConnected.
2. The ProductInfo value PRODUCT_PRERELEASE_ARM now correctly sets the underlying processor type to ARM
PJN / 30-04-2015 1. It turns out that the new detection code to detect Windows 8.1 with Bing was flawed in the previous release as the
PRODUCT_CORE_* ProductInfo values just means the standard / core version of Windows 8.1. The code has now been updated to
use a registry search to correctly detect if Windows 8.1 with Bing is installed.
PJN / 17-05-2015 1. Updated all code references of Windows Server 10 to Windows Server 2016.
2. Added support for the following product types: PRODUCT_PROFESSIONAL_EMBEDDED, PRODUCT_MOBILE_CORE,
PRODUCT_EMBEDDED_INDUSTRY_EVAL, PRODUCT_EMBEDDED_INDUSTRY_E_EVAL, PRODUCT_EMBEDDED_EVAL, PRODUCT_EMBEDDED_E_EVAL,
PRODUCT_NANO_SERVER, PRODUCT_CLOUD_STORAGE_SERVER, PRODUCT_CORE_CONNECTED, PRODUCT_PROFESSIONAL_STUDENT,
PRODUCT_CORE_CONNECTED_N, PRODUCT_PROFESSIONAL_STUDENT_N, PRODUCT_CORE_CONNECTED_SINGLELANGUAGE,
PRODUCT_CORE_CONNECTED_COUNTRYSPECIFIC, PRODUCT_CONNECTED_CAR, PRODUCT_INDUSTRY_HANDHELD, PRODUCT_PPI_PRO,
PRODUCT_ARM64_SERVER, PRODUCT_EDUCATION, PRODUCT_EDUCATION_N, PRODUCT_IOTUAP, PRODUCT_CLOUD_HOST_INFRASTRUCTURE_SERVER,
PRODUCT_ENTERPRISE_S, PRODUCT_ENTERPRISE_S_N, PRODUCT_PROFESSIONAL_S, PRODUCT_PROFESSIONAL_S_N,
PRODUCT_ENTERPRISE_S_EVALUATION & PRODUCT_ENTERPRISE_S_N_EVALUATION.
3. Remove the word Installed from most of the methods.
4. The download now includes a Winver14.sln solution for Visual Studio 2015 RC. This now allows you to build an ARM
binary of DtWinVer which you can deploy to Windows IoT Core on the Raspberry Pi 2. Also included is a precompiled
ARM binary of DtWinVer.
5. Updated the code to clean compile on VS 2015 RC
PJN / 19-09-2015 1. Code now always tries to use "RTLGetVersion" to get the underlying OS details. Previously it would only do this if
the code detected that it was running on Windows 8.1 or greater. Also removed the GetRealVersionNumbersFromRegistry
method as this returns 6.3 on Windows 10 and as such is just unreliable. Please note that DtWinVer will still report
incorrect OS details if compatibility mode is enabled for your application. Thanks to Dave Silber for prompting this
investigation.
PJN / 04-03-2016 1. Updated copyright details.
2. Provided IsWindows10RTM, IsWindows10Version1511 & IsWindows10Redstone functions. Also updated the sample app to
report this information.
PJN / 04-04-2016 1. Updated code to refer to Windows 10 Anniversary Update instead of Windows Redstone.
PJN / 25-07-2016 1. Reworked the code in test.cpp to correctly report on versions of Windows Server Enterprise. This follows testing on
Windows Server 2016 Standard Technical Preview 5.
PJN / 17-08-2016 1. Renamed IsWindows10AnniversaryUpdate method to IsWindows10Version1607.
2. Provided new IsWindows10Redstone2, IsHolographic, IsSubscription, IsUtilityVM, IsWorkstation, IsAzure &

PRODUCT_ENTERPRISE_SUBSCRIPTION, PRODUCT_ENTERPRISE_SUBSCRIPTION_N, PRODUCT_DATACENTER_NANO_SERVER,
PRODUCT_STANDARD_NANO_SERVER, PRODUCT_DATACENTER_A_SERVER_CORE, PRODUCT_STANDARD_A_SERVER_CORE,
PRODUCT_DATACENTER_WS_SERVER_CORE, PRODUCT_STANDARD_WS_SERVER_CORE, PRODUCT_UTILITY_VM,
PRODUCT_DATACENTER_EVALUATION_SERVER_CORE, PRODUCT_STANDARD_EVALUATION_SERVER_CORE, PRODUCT_PRO_WORKSTATION,
PRODUCT_PRO_WORKSTATION_N, PRODUCT_PRO_FOR_EDUCATION, PRODUCT_PRO_FOR_EDUCATION_N, PRODUCT_AZURE_SERVER_CORE,
PRODUCT_AZURE_NANO_SERVER, PRODUCT_IOTUAPCOMMERCIAL & PRODUCT_MOBILE_ENTERPRISE
4. Added SAL annotations to all the code.
PJN / 13-10-2016 1. Updated the code to report correct values on Windows Server 2016 RTM. It seems that on Windows Server 2016 Standard
RTM that the VER_SUITE_ENTERPRISE flag is set in OSVERSIONINFOEX::wSuiteMask. I'm not sure if this is a genuine bug
in Windows Server 2016 but I have modified the code to handle this by removing the COSVERSION_SUITE_ENTERPRISE flag if
the code successfully calls GetProductInfo which gives the correct result after calling GetVersionEx.
PJN / 03-01-2017 1. Updated copyright details.
2. Renamed IsWindows10Redstone2 method to IsWindows10Version1703.

2. Tested the code on Windows 10 version 1703.
3. Verified the code compiles cleanly on VC 2017.
PJN / 17-04-2017 1. Provided a new IsWindows10Redstone3 method
PJN / 18-04-2017 1. Removed unused COSVersion::GetNTCurrentVersionFromRegistry and COSVersion::GetNTCSDVersionFromRegistry methods
from codebase.
2. Updated the code to support the Windows 10 UBR "Update Build Revision" value. For example the latest version of
Windows 10 at the time of this release was Version 1703, OS Build 15063.138. The 138 in the value is the UBR.
PJN / 19-06-2017 1. Renamed IsWindowsCloud method to IsSEdition.
2. Renamed IsSEdition method to IsLTSB.
PJN / 27-09-2017 1. Renamed IsWorkstation method to IsProWorkstations and reworked the COSVERSION_SUITE3_WORKSTATION enum to be

2. Added support for detecting VER_SUITE_COMMUNICATIONS, VER_SUITE_SMALLBUSINESS_RESTRICTED &
VER_SUITE_EMBEDDED_RESTRICTED. Note that there is a new VER_SUITE_MULTIUSERTS define in the latest Windows 10 SDK
but it does not fit in the current WORD sized element in OSVERSIONINFOEX structure so I have not included any
code to support this new define.
3. Added support for detecting PROCESSOR_ARCHITECTURE_NEUTRAL, PROCESSOR_ARCHITECTURE_ARM64,
PROCESSOR_ARCHITECTURE_ARM32_ON_WIN64 & PROCESSOR_ARCHITECTURE_IA32_ON_ARM64 architectures
PJN / 04-02-2018 1. Updated copyright details.
