I dont know how it happened but for some reason, my taskmgr is missing. Could someone please be kind enough and upload an x64 version of taskmgr.exe from build 9200 from the system32 folder? This is a much easier solution than digging through restore points, restoring or repairing
You could also extract the file from the Windows DVD/ISO. Of course its included in the install.wim, which can be opened with 7zip.
