i was trying to increase my laptops performance and trying to either remove unnecessary startup items using "msconfig" or to remove corrupted files from my hard drive, and i restarted my laptop and everything, but now everything has gone from my desktop. loads of programs in the "Start" menu now dont work and say "class not registered" when i click on them. Only the programs in "All Programs" work, but i have to click "Run as Administrator" for them to work, not even the sound works?? truth is i have no idea what's gone wrong, and i cant really remember what i did for it to happen, i would be eternally grateful if someone could cure my ignorance

Trying restoring your pc to nearest checkpoints it works dont worry. Do this in safe mode

[derekminivan]

ive tried to restore in both safe mode and normal windows startup but it says i have no restore points, yet i created a restore point a few days before the problem.

[derekminivan]

i tried to do this, but i can download it but when i open it, it doesn't work, i cant download and open files like that now.

What did you mess with or change in these tabs?

[derekminivan]

i genuinely cannot remember what i did exactly, im not being very helpful. The only major thing i can mention, is in the start menu the tabs on the right hand side say "Class not registered" so i cant open "My Computer"

Unless your hard drive is faulty, there were no "corrupted files" on your system. Where did you delete files? Are they recycled?

It looks like you may need to reinstall.

[derekminivan]

The problem is i dont know how to check where the deleted files are. what do i need to reinstall do you think?

[Elvandil]

Reinstall Windows and your programs.

[derekminivan]

ive tried that, but when it starts the process of reinstalling it, it doesn't work

Backup any documents/pictures/songs/etc. before this!!! Next step will DELETE ALL information!!

Boot the computer using a Windows 7 DVD and perform a clean install (will DELETE ALL information) and then reinstall your applications and transfer your documents/pictures/songs/etc.

What does "doesn't work" mean?

You probably disabled some important services from running. Go to Services and enable ALL of them (I guess), then restart and see if that works. Then at least you'll know that was the problem, and then can try carefully disabling ones you don't need

[derekminivan]

and how do i open services?
