Sometimes we stuck on a program which says that it requires Windows Vista SP1/SP2 to run, while you are running Windows Vista SP0, but at times you might not feel to upgrade through internet at that very moment, or your internet connection is at rest, or whatever the case may be, and at the same time you want to use that software too.

Here’s the solution to this problem, so that you can upgrade your Windows Vista SP0 to SP1/SP2 without even getting connected to internet.

There is a registry tweak which converts your Vista SP0 to SP1/SP2.

*For upgrading XP SP2 to SP3, see here...

Open Registry Editor. It can be opened by typing “regedit” in RUN and press Enter. (Windows Vista, type “regedit” in start menu search and press enter.

Now go to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows

In right-side pane, look for “CDSVersion” and change its value to 0x00000100 (for SP1) / to 0x00000200 (for SP2), to do this, double-click on “CDSVersion” and type ‘100’ (for SP1) / ‘200’ (for SP2) and press ok and exit Registry Editor.

*Remember, not to mess with other stuff in Registry Editor.

Now re-start your PC to see changes.

It’s Done.
