Windows 7 Ultimate on a Lenovo T410 Laptop. I'm an end user. I think somewhat sophisticated, but I never use regedit.
When acrobat did an update it somehow changed all of my exe file associations to open as a file in acrobat in one proflie. After 6 hours on the phone with microsoft and another 3 hours with Norton, norton solved the problem with my main work profile.
But I'd forgotten that at the same time all of my exe files in a different profile were opening in Windows Media Center (I still blame Acrobat).
Unfortunately, I can't run Tweaking.com on the bad proflile (I'm really sure it is NOT a virus--just somethign acrobat did in an update)--because when I click on it, it brings up the Windows Media Center.
I ran tweaking in safe mode with networking in the profile that works, but that didn't change the file associations in the other profile.
And I purchased the pro license.
Thanks.
