How do I reinstall Windows 7 task Manager ?

Recently I had occasion to use the task manager feature, but when it opened, it opened only the Processes Window, and no other tabs are available. In order to close it I have to use the process window do shut even the task manager down. None of the other tabs are available, even after multiple reboots.

Applications, Services, Performance, Networking, Users. None of these tabs are available, nor is there a file manager menu line. I am assuming I have to re-install the feature. How do I do this?

Have you made any changes to your computer?

Method 1:

I would suggest you to run the system file checker and check.

Method 2:

I would also suggest you to refer the link and check (which also applies for windows 7).

Method 3:

I would suggest you to download and install Microsoft safety scanner and run the scan and check.

Note: The Microsoft Safety Scanner expires 10 days after being downloaded. To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again.
