Not Able to Access/Open Task Manager

6 posts in this topic

Hi guys!

I've Windows Vista Home PRemium x64 installed on my machine. From few days I've not been able to open up Windows Task Manager. Previously, when I right clicked on taskbar a menu appeared and I selected Task Manager from it. Now, when I open the same menu the option Task Manager appears in grey colour as if it has been disabled. And when I perss Ctrl + Alt + Del, a screen appears with many options on it but the option for Task Manager is missing. I keep installing updates from the Microsoft Website. So, is it due to any latest update? Please suggest a solution. Thx in advance.

or you can not be an R-tard and just type


also want to check out sysrun.exe [fullpathto.exe] or psexec.exe -i to run as SYSTEM with process explore you have escalated privileges and can see more in the registry too.

runas /user:Administrator "cmd.exe"

I got the solution. Sharing it over here.

Click on this link

I was amused by that link, since the page is titled "Why is Task Manager Disabled?", and it contains the sentence, "Why is task manager grayed out?"

The page does not, however, answer either of those questions (other than to say "um, maybe it might be some spywarez lol"). It simply gives the registry fix to re-enable it. Thus, when it happens every 7 days, you get really good at going into the registry and fixing it, instead of figuring out what exactly is causing it. :)

(Although I guess in a very literal sense, the task manager is greyed out because of that registry setting....)
