Visual Studio 2008 Product Key in Registry? [closed]

Answer 1

For 32 bit Windows:

Visual Studio 2003:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\7.0\Registration\PIDKEY

Visual Studio 2005:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Registration\PIDKEY

Visual Studio 2008:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Registration\PIDKEY

For 64 bit Windows:

Visual Studio 2003:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\7.0\Registration\PIDKEY

Visual Studio 2005:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\8.0\Registration\PIDKEY

Visual Studio 2008:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\9.0\Registration\PIDKEY

Notes:

• Data is a GUID without dashes. Put a dash ( – ) after every 5 characters to convert to product key.

• If PIDKEY value is empty try to look at the subfolders e.g.

  ...\Registration\1000.0x0000\PIDKEY

  or

  ...\Registration\2000.0x0000\PIDKEY

Answer 2

Just delete key:

HKEY_CURRENT_USER/Software/Microsoft/VCExpress/9.0/Registration

Or run in command line:

reg delete HKCU\Software\Microsoft\VCExpress\9.0\Registration /f

Answer 3

I found the product key for Visual Studio 2008 Professional under a slightly different key:

HKLM\SOFTWARE\Wow6432Node\Microsoft\MSDN\8.0\Registration\PIDKEY

it was listed without the dashes as stated above.

Answer 4

For Visual Studio 2005:

If you do have an installed Visual Studio 2005 however, and want to find out the serial number you’ve used to install it because you don’t have a clue where you put that shiny sticker, you can. It is, like most things in Windows, in the registry.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Registration\PIDKEY

In order to convert the value in that key to an actual serial number you have to put a dash ( – ) after evert 5 characters of the code.

For Visual Studio 2008 it's supposed to be:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Registration\PIDKEY

However I noted that the the Data field for PIDKEY is only filled in the 1000.0x000 (or 2000.0x000) sub folder of the above paths.
