How do you un-replace task manager? Every time i tap replace task manager, it doesn't switch to undo.
Check with Process Monitor what it tries to change (Probably a reg-key) and then look in the security tab of it if you have write rights or change it yourself.
There are specific locations in the registry. Navigate to them and delete the "Debugger" key which is stored there. Code: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\taskmgr.exe HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\taskmgr.exe Or the easy way is to launch AutoRuns (with administrator privileges) and go to the section "Image Hijacks". From there you can simply (a) untick the "taskmgr.exe" entry (if you want to switch back to Process Explorer at a later time) or you can (b) delete the "taskmgr.exe" entry.
Thanks for all of your help. I found out it wasn't working with process explorer64. When i started up process explorer, non 64, i was able to switch back.
