A friend of mine recently bought a pc from a possibly dodgy shop without listening to my advice doh.gif

Is there anyway to check if the windows installation has been tampered with(different kernel and/or similar stuff)?

Does he have the original CD? If yes, he should simply reinstall, that will ensure clean system.
Otherwise, I don't know of any way to do an integrity check smile.gif

But, countrary to what M$ says, there are very few people who deliberately infect Win installations.

A non-legit key can also activate, if the WGAT is hacked. Unfortunately I haven't found anything that can prove it one way or another. You can download the Windows Genuine Activation Tool from M$, but there are certain hacks that go even over that protection and still show "activated" for a fake key.

As for the installation itself... I would do that: make a restore point, the download the trial versions of every major Atni-Virus kit you can remember - Kasperski, Avast, AVG, Avira, Panda, everythin. Run scans from all of those, then uninstall them (except the one you preffer smile.gif ). That gives some chance that the system would be clean.

You could try verifying the integrity of the core windows files through command prompt using the:
sfc /scannow
command in a command prompt window running in administrator mode - it might spot if windows files have been tampered with.
