Here are solutions to some common problems with using Task Manager.
Open Task Manager by right-clicking the taskbar and then clicking Task Manager.
You can also open Task Manager by pressing CTRL+ALT+DELETE, and then clicking Start Task Manager.
If Task Manager won't start, your computer might have a virus. Make sure that you have up-to-date antivirus software installed on your computer, and then search the Microsoft website for the latest virus information. If your computer does not have a virus and you are connected to a network, check with your system administrator to find out if Task Manager has been turned off on your computer.
Task Manager might be set to Hide When Minimized. When this setting is activated, Task Manager only appears as a green graph icon in the notification area, rather than appearing in the taskbar as other programs do when minimized.
Click the Options menu, and then make sure that there is no check mark next to Hide When Minimized. The next time you minimize Task Manager, it will appear on the taskbar.
Task Manager has two different views. To see the view that includes menus and tabs, double-click the border of the Task Manager window. To switch back to the view without menus and tabs, double-click anywhere in the border around the tabs.
By default, Task Manager is set to always display on top. To change the default view of Task Manager so that it displays behind other open windows, click the Options menu, and then click Always On Top (which removes the check mark beside the command). If you want Task Manager to stay on top of all other open windows again, click the Options menu, and then click Always on Top (which restores the check mark beside the command).
If Task Manager has been disabled, you can re-enable it if you have administrator privileges on the computer.
This procedure requires you to edit the registry. An incorrect change to your computer's registry could render your computer inoperable. We strongly recommend that you back up the registry before making any changes. For more information, see Back up the registry.
Open the Registry Editor by clicking the Start button , typing regedit into the Search box, and then pressing ENTER. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Navigate to the following location: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies
Double-click System, double-click DisableTaskMgr, change Value data to 0, and then click OK.
Click the Start button , type gpedit.msc in the search box, and then press ENTER.
Under User Configuration, double-click Administrative Templates.
Double-click System, and then click Crtl+Alt+Del Options.
Double-click Remove Task Manager, click Disabled, and then click OK.
If the Remove Task Manager properties appear dimmed, your network administrator has prevented you from changing these settings. Contact your network administrator to have Task Manager enabled.
