Thursday, November 29, 2007
Here's an easy way to tell which .NET Framework 2.0 service pack is installed. Open a command line and enter the following command as a single line:

reg query "HKLM\software\Microsoft\NET Framework Setup\NDP\v2.0.50727" /v SP

For .NET Framework 3.0, enter:

reg query "HKLM\software\Microsoft\NET Framework Setup\NDP\v3.0" /v SP
The commands will return the REG_DWORD value for the SP version (0x0 for RTM or 0x1 for SP1).
