Windows 7: Will in-place upgrade of working win7 destroy my programs?

Will in-place upgrade of working win7 destroy my programs?

I have a Win7-64 box that works perfectly. Except that I cannot install any driver past 270.61 for my nVidia GTX-580. nVidia said this is a known problem with many users due to "The install failed because a control panel binary is failing to register because of a missing dependency." In other words, one of their installers/un-installers has removed a dll that's needed. I don't have a free week of my life to re-install everything on the box from scratch. It was suggested on the EVGA forum that I might: " in-place upgrade install of the OS. In other words, insert your OS disk. Start the install and select 'Upgrade'. What will this do to me? I have high end software like Maya, CS6, SQL Server - and many others (but no games, this is a business machine with no extra software). Thanks!!!!

It can fail like any install, but often will roll back the changes its already made.

You'd need to back up a System image to have a sure path back: Backup Complete Computer - Create an Image Backup

Is this known to work for this specific issue because it isn't intuitive that it would necessarily work for what you describe. But it's possibly worth a try short of reinstalling.

I'd post up the issue again but in our Drivers forum where someone may know for sure.

I'd never be afraid of a Clean Reinstall - Factory OEM Windows 7 as it's not that bad and almost always better than getting a new computer considering all of the crapware that comes preinstalled.
