How to detect if Visual Studio 2005 SP1 is installed on Windows

If you don't need to be specific about a particular Visual Studio 2005 SKU, you can detect SP1 for a particular written language (for VSTS and TFS) or for a particular project language (for Express SKUs) using an older registry key under,

HKEY_LOCAL_MACHINE\Software\Microsoft\Active Setup\Installed Components\{PatchCode}

You can find the {PatchCode} in the .msp file. In Windows 2003 and earlier platforms, you'll see this as the Revision number property in the properties Summary tab in Windows Explorer. In all cases, you can query the Summary Information stream or open the .msp file in Orca, then click the View -> Summary Information menu item.

For the English Visual Studio 2005 Service Pack 1 for Standard, Professional, and Team editions (VS80sp1-KB926601-X86-ENU) an example of the registry key above follows.

HKEY_LOCAL_MACHINE\Software\Microsoft\Active Setup\Installed Components\{D93F9C7C-AB57-44C8-BAD6-1494674BCAF7}

You can also determine the service pack level of a more general, larger scope by reading a REG_DWORD registry value named SP from under,


…and for a specific language SKU using a sub-key,


Product families are pretty broad in scope, and include for "Whidbey":

URT (.NET Framework, once known as the Universal Runtime)
VB (Microsoft Visual Basic 2005 Express)
VC (Microsoft Visual C++ 2005 Express)
VCS (Microsoft Visual C# 2005 Express)
VJS (Microsoft Visual J# 2005 Express)
VNS (Microsoft Visual Web Developer 2005 Express)
VS (Visual Studio 2005 Standard, Professional, Team Suite, etc.)
VSTF (Visual Studio 2005 Team Foundation Services)
An example using the English Visual Studio 2005 Team Suite Service Pack 1 of the registry keys above follows. Under each key you would find a registry value named SP set to 1.


Visual Studio 2005 Express SKUs will always use the ProductEdition of EXP, so you can combine the ProductFamily values documented above with EXP to form registry keys like the following, for Visual C# 2005 Express.
