What if the Win7 System Task Manager has been deactivated by the system administrator?

The workaround is as follows:

1, first use the shortcut key to press "Win+r", and then enter the "gpedit.msc" command in the running column and press ENTER;

2. Open the Group Policy Editor window and expand the User Configuration-Admin template-system-ctrl+alt+del option.

3, then we can find on the right and double-click the "Delete Task Manager" option, then the default configuration set to Not configured, click OK to save it.
