Hi guys,
I recently upgraded from Windows Vista Home Basic to Win7 Home Premium. Now, when I try to run any program that I hadn't run in Windows Vista, it gives me an error message saying "Windows cannot verify the digital signature for this file. A recent hardware or software change might have caused this" or something on similar lines. I can't run any updates because of 'An unknown error'. I had upgraded with the help of a USB Flash drive. I also tried disabling digital signature checking using F8, but to no avail. I can't even re-enable AVG Anti-Virus, which i had disabled during my upgrade to speed up the process. Any solutions?

I tried the test mode thing by restarting my laptop in safe mode with cmd, and typed:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
Now, there's the test mode thing on my desktop, but Windows 7 isn't doing anything differently.

Thanks, but what about my files? I upgraded from vista instead of a clean install for my files... I don't exactly wanna re-install win7 unless there's no other go. Re-installing would be a last resort. Any registry changes that can do the trick?

I'm thinking another Windows 7 install too. It would likely be easier than any "manual" fix out there, if there is any.

Just backup your files on a flashdrive or external harddrive, that way you don't lose them.

Well, i should've made that files, softwares that are very touchy about the installation and generally don't install easily, and my settings... Guess that's the only way.
I think I'll have to mark this solved, although it doesn't seem to be.
Guys looking for the solution: RE-INSTALL WINDOWS 7

You don't have to mark this as solved until it's solved.

Regardless, someone else may have another idea.

Oh. Ok then. THIS POST IS NOT YET SOLVED.
I know I sound very immature, but this thing is driving me NUTS. I seriously don't wanna reinstall win7.
