Windows 7 - Things do not work on Windows 7

Okey, heres the thing. I do not really know what to call this problem, but things such as "Screen resolution, Display, Windows Update, Advanced network sharing options" and many many other things can't be opened. I do not get any errors, although i do get this one error when i try to play movies in Windows Media player,

"C:\Users\Frederik\Desktop\TeamFortress2-HeavyWeaponsGuy.wmw"

"Server execution failed." and then i can only press OK.


I didn't know where to post this, and i am also very new to this forum, i actully joined 5 minutes ago.

Thanks in advance

Is this a fresh install, or did it happen "out of the blue?"

Sounds like you need to try a repair install, or a fresh install.

It kinda came out of the blue, just suddenly the things stopped working. It was like 1 or 2 weeks ago.

have you tried using system restore to go back to before this issue presented itself?

No, i haven't but i looked in system restore and it only goes back like 5 days..

Have you scanned for viruses?

At this point, the best thing to do would be to backup your data and do a clean install. It will be much better in the end than trying to fix this botched one.

You didn't say whether is was a "clean" install or not?

What exactly is a "Clean" install? :O

A clean install is a fresh installation of the OS rather than an upgrade, and is the preferred method among experienced users..
