Have a look at the fixes on this web site.
They are all Registry fixes. You should back-up your registry before you make any changes. Look at this site from MS for instructions.
When I want to open one of this extentions (.lnk, .exe,.bat,.reg..) windows XP wants me to choose wich program i use for them (sry english very poor)..
I found this http://www.dougknox.com/xp/file_assoc.htm
but the problem is that if i try to download and open one of them fix, for exemple the .reg fix, it s also a .reg file, and i can t open it.
Can you help me ?
(I also tried a scan disk & antivirus but didn t help.)
