Reinstall of SP1

[lafargeotte]

Just after some advice here.

Basically I would like to reinstall Service Pack 1.

I cannot go back in time, as I installed SP1 when it first came out. It has been fine until recently. Because all has been fine I deleted all the old files and System Restore does not go back far enough.

I have the SP1 install.exe file (537mb), but when I try to install it I cannot as it tells me SP1 is already installed, which of course it is.

So, can I edit the registry, and kid the OS into thinking it is Windows 7 (but before SP1), so that I can reinstall SP1. I believe the relevant key is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

Thanks in advance.

Hello Paul,

If you didn't use the Windows 7 SP1 Disk Cleanup Tool, then you should be able to just uninstall SP1 and install it again afterwards.

If you did, then I'm afraid the only way is to do a clean reinstall of Windows 7.

What is wrong for why you wanted to reinstall SP1? Maybe we could help with that.

Hope this helps,
Shawn
