It is the Windows Task Manager. It is what open up in order to see the taskmgr.exe file in the first place. It is completely harmless, when it's in your System32 folder. If the rare occasion happens and it's NOT found in your System32 folder, then it's most likely a virus/trojanand SHOULD BE DELETED.

Is a virus!
Windows Task Manager (Ctrl + Alt + Delete). It lets you see everything your CPU is trying to do. Great for killing unwanted programs to free up RAM - especially for older computers fighting to work in today's world. It's safe, but if it all of a sudden wants to access the internet, run a virus scan to keep it clean. I use Trend's PC Housecall. It's free, and kept my comp clean for years!

im not able to click on taskmanager error taskmgr.exe
The REAL Task Manager is the CTRL+ALT+DELETE and it's located in System32. The other one is NOT in System32, it has a high CPU level, and is a trojan DISGUISED as Task Manager. DELETE any thing that says Task Manager that is NOT in System32. It can still information such as bank account numbers, passwords, and it includes stealing idenity. DELETE IT NOW!
It stands for Task Manager
an easy way to delete all "other" taskmgr.exe files you can use the Windows rule that a running item can't be deleted... first run the real taskmgr by pressing Ctrl + Alt + Del then open any folder and click search then search for "all files and folders" make sure your search searches hidden files and folders and system folders then when the search is complete delete all the "taskmgr.exe" then of course the real one can't be deleted since it is running
This is totally not dangerous! It should use up around 2,000k!

Best practices for resolving taskmgr issues

A clean and tidy computer is the key requirement for avoiding problems with taskmgr. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
