After I uninstalled MS SQL Server “Denali” CTP3, my Task Manager cannot be launched. Every time I try to launch it, it gives me an error:
Windows cannot find ‘C:\Windows\system32\taskmgr.exe’. Make sure you typed the name correctly, and then try again.
How to fix it?
Before I installed SQL Server “Denali”, I used Process Explorer to replace my Task Manager, and it seems that the uninstallation of “Denali” messed up Process Explorer. But since Task Manager has been replaced by Process Explorer, it will not be able to find the correctly file when Task Manager is being launched.
What I did was to rerun Process Explorer, then go to Options –> Replace Task Manager, then close Process Explorer.
If you want to go back to the built-in Task Manager in Windows, then repeat the above step (click Replace Task Manager again).
Hope this helps.
