Among its functions, several tabs stand out, such as:

- Performance: provides information about CPU, memory, disk and network.
- Application history: documents resource usage by application.
- Home: controls which programs start with Windows.
- Users: reports on the activity of each active account.
- Details and Services: They provide deeper access to system processes and services.

- Use the combination Ctrl + Shift + Esc to open it directly.
- Right-click on the taskbar (or Windows button) and choose “Task Manager.”
- From the Run command: Press Win + R, writes taskmgr and hit Enter.
- Search for “Task Manager” in the Start menu and right-click to run it as administrator.
Reasons why Task Manager won't open
There are multiple reasons why the Administrator may stop working, among the most frequent:
- Corrupted system files due to failed updates or improper shutdowns.

Solutions to activate or restore Task Manager
Depending on the source of the problem, you can apply different solutions. Here we show you all the viable alternatives, from the simplest to the most technical.
1. Reboot the system
It seems basic, but many times a simple restart can fix temporary errors. that prevent the Manager from opening. This is the first thing you should try.
2. Update Windows
Microsoft releases updates to fix known bugs. Go to Settings → Update & Security → Windows Update and check for available updates. Install them and restart.
3. Create a new user account
If the Manager doesn't work on your current account, try a new one.. Sometimes profiles get corrupted, and it's easier to create a new one than to repair everything manually.
From Settings → Accounts → Family & other users → Add another person to this PC. You can choose a local (non-Microsoft) account if you don't want to sync.
4. Check the Windows registry
One of the most common causes is that the DisableTaskMgr value is enabled, which prevents the tool from starting. To fix this:
- Press Win + R, writes regedit and hit Enter.
- Navigate to HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ System
- Search for a value called DisableTaskMgr. Double-click it and change its value to 0.
- Restart the system.
5. Use Command Prompt or PowerShell
Run CMD or PowerShell as administrator and type this command:
REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f
Then restart your computer.
6. Activate it from the Group Policy Editor
This is only available on Pro or Enterprise versions of Windows:
- Press Win + R, writes gpedit.msc and press Enter.
- Navigate to User Configuration → Administrative Templates → System → Options Ctrl+Alt+Del.
- Double-click “Remove Task Manager.”
- Select “Disabled” or “Not Configured.”
Other possible reasons: Task Manager paused
If you manage to open the Manager but it does not update the process or resource information, the tool may be in paused mode or with a very low update rate.
To check, open the Manager, go to the View → Refresh Rate menu and make sure it is set to “Normal” or “High”. If you are “Paused”, you will not see any real-time changes..
Conflicts with antivirus, malware, or corrupted files
Some antivirus may disable the Administrator by default.. Try uninstalling them temporarily to rule out whether they are causing the error. Also, perform a full system scan with Windows Defender or tools like Malwarebytes.
You can also use internal tools such as:
- SFC / scannow: to repair system files.
- DISM / Online / Cleanup Image / RestoreHealth: to repair the system image.
