Task Manager and RegEdit has been disabled by your administrator!!

I don't actually know how to recover a pc once it got this kind of problem. But I'm sure it's caused by malware or virus. I usually back everything I can and make sure they're all clean and then I make a fresh format of my computer. Hahaha

I agree with the above posts, this looks like you've had some sort of Virus attack, there is lots of information at http://www.pcshell.com/support/registryeditordisabled.shtml (not a referal link) including several possible solutions Good luck

If your computer is your own and not linked to a network (in an office, for example, so that you have to log in to an account) this is a virus. Download a good antivirus solution - AVG Free, Avast! (free) or Avira (free) - and run a full scan. Since the virus may have restricted access to certain things, you may have to download the antivirus package on another computer, put it onto a CD or USB stick and install it from there. You may also have to start the computer in 'Safe Mode' in order to download and/or scan your disk.

Probably due to virus. try to scan or use PCMAV SMADAV To enable Task Manager, try to copy-paste it on the run: REG add HKCU \ Software \ Microsoft \ Windows \ CurrentV ... / v DisableTaskMgr / t REG_DWORD / d 0 / f

Go and download Process Explorer and in options replacing it with your simple Task manager Process Explorer - options - Replace with existing Task manager is an option Ok no need of complexity
