Every program I try to open, windows tries to open it in Notepad. This is very weird and I can't figure out how to fix it. Can anyone help?? thanks a lot!! screenshot

Use the file type Set Associations wizard. Go to Control Panel- Programs- Default Programs- Set Associations. You can also use the Open With command. Right click the icon, choose open with, select the program needed and make sure Always use the selected program to open this kind of file is checked.

looks like thisd is not icon cache or something... all file type associations are replaced with notepad... oops... you may need to change all types associations or restore from a previous restore point or format!
I dont know how did you manage that? did you use any tool to play with associations?
HainKurtSr. System AnalystCommented:
or maybe you just replaced exe extension! run regedit and go to this key

I think HainKurt exe suggestion will fix u r issue.

Run system restore will fix your problem.

You need to download a Windows 7 Recovery Disk or use your Windows 7 Setup DVD to start your PC and launch system restore to go back to a restore point before you make the assocaition change to notepad.

Windows Vista/7 System Restore (GUIDE)

When a problem appears in Windows 7 and there are no clues from google, it seems to me the last resort is to use system restore as Vista is much better in system restore than the system restore in XP. System Restore in Vista is just like a time machine to go back to the exact state when the problem does not exist. But the drawback is that it consumes a lot of hard disk apace and it will restore the applications that you have removed and old version of document on desktop,

So, before your use System Restore, make sure all user data has been properly backup as it is just too powerful if Vista thinks that the path you stored your data is part of the system folders.

In a nutshell, System Restore can reduce the time of troubleshooting (except the problem is caused by hardware failure) but it must be used with due care.
