There must be a way.......

There must be a way to be sure all Vista and W7 system files are signed
(not corrupted). I've researched and have not found a way. Can anybody
help?

Try the SFC commmand. See this tutorial: 'SFC /SCANNOW Command - System
File Checker - Windows 7 Forums'
(http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html)

Thank you. However, I've done exactly that and it stops at 56% and a
message tells me that it cannot complete or perform this process. Do you
know of any way to find out why it does this? Thanks again....

You may want to try a '*Repair Install*'
(http://www.sevenforums.com/tutorials/3413-repair-install.html).

Thanks, but I don't have Windows 7 - which is what this article is about.
I'll have to look for a "Repair Install" for Vista Home Premium (unless
you already know where to go). Thank you......

I believe it should be the same for Vista. Simply perform an Upgrade
while in Windows.

Do you know if there are any risks?

but your programs and data will not be touched.

Thank you.
