Quick checks (do these first)

Try shortcuts: Press Ctrl+Shift+Esc or Ctrl+Alt+Del → Task Manager.
Right-click Start: Choose Task Manager.
Run taskmgr: Press Win+R, type taskmgr, Enter.

If Task Manager opens, problem solved. If not, continue.

Step-by-step fixes (try in order)

Restart Windows Explorer

Press Ctrl+Shift+Esc (if Task Manager opens) or open Command Prompt.
In Task Manager: File → Run new task → type explorer.exe → OK.
Or in Command Prompt: taskkill /f /im explorer.exe && start explorer.exe

Check Group Policy (Windows Pro/Enterprise)

Press Win+R, type gpedit.msc, Enter.
Navigate: User Configuration → Administrative Templates → System → Ctrl+Alt+Del Options.
Double-click Remove Task Manager → set to Not Configured or Disabled → Apply → OK.
Run gpupdate /force in Command Prompt.

Fix via Registry (all Windows editions)

Press Win+R, type regedit, Enter. Back up registry: File → Export.
Navigate: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
If a DWORD named DisableTaskMgr exists and is set to 1, double-click and change to 0 or delete the value.
Also check HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System for the same value.
Restart or sign out/in.

Scan for malware

Run a full system scan with Windows Defender: Settings → Update & Security → Windows Security → Virus & threat protection → Quick/Full scan.
Optionally use a reputable on-demand scanner (Malwarebytes). Remove threats and reboot.

Repair system files

Open elevated Command Prompt (Win, type cmd, right-click → Run as administrator).
Run: sfc /scannow
After SFC completes, run: DISM /Online /Cleanup-Image /RestoreHealth
Reboot and check Task Manager.

Restore Task Manager via .reg file (one-click)

Create a text file named restoretaskmgr.reg with:
Code
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System] “DisableTaskMgr”=dword:00000000

Double-click to merge, then restart. (Backup registry first.)

Create a new user account

If corruption is limited to a profile: Settings → Accounts → Family & other users → Add someone else to this PC. Sign in to check Task Manager.

System Restore or Reset

Use System Restore to revert to a point when Task Manager worked.

As last resort, Reset this PC (keep files) under Settings → Update & Security → Recovery.

How to confirm and prevent recurrence

Confirm: Task Manager opens via shortcuts and lists processes.

Prevent: Keep Windows updated, run periodic malware scans, avoid unknown executables, and do not change Group Policy or registry unless necessary.
