Useful follow-up notes after the thread: and covered the common policy/registry fixes and the OP () reported success. Because malware that disables tools often leaves persistence behind, a quick checklist of extra diagnostics and recovery steps is useful when the problem returns or when restrictions reappear on other accounts.

Run a non-interactive inspection of startup and injected components with Sysinternals tools: Autoruns to reveal auto-start entries and Process Explorer to inspect running processes and handles. These tools make it easier to spot unsigned or oddly located binaries that standard scanners miss (Autoruns, Process Explorer). Repair possible corrupted system files and component store metadata before concluding the infection is gone. Common recovery commands used for that purpose are shown below.

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

If Task Manager or Run disappear again after cleanup, try booting to Safe Mode or use an offline scanner so active malware cannot block removal. Microsoft provides a downloadable on-demand scanner for deeper checks (Microsoft Safety Scanner). As a diagnostic, create a fresh local administrator account — if the new profile behaves normally the issue may be user‑profile specific. When repair efforts fail or core system files are damaged, prefer a clean image or reinstall rather than leaving a partially cleaned machine in production. Change account passwords and fully update OS and security software after remediation.

Hello,

Do as suggested below :

1. Verity that the "Local Group Policy" or "Domain Group Policy" doesn’t block you from using

"Task Manager".

1.1 "Local Group Policy"

a. Go to "Start" -> "Run" -> Write "Gpedit.msc" and press on "Enter" button.

b. Navigate to "User Configuration" -> "Administrative Templates" -> "System" -> "Ctrl+Alt+Del Options"

c. In the right side of the screen verity that "Remove Task Manager"" option set to "Disable" or "Not Configured".

d. Close "Gpedit.msc" MMC.

e. Go to "Start" -> "Run" -> Write "gpupdate /force" and press on "Enter" button.

2. Verity correct registry settings::

a. Go to "Start" -> "Run" -> Write "regedit" and press on "Enter" button.


Warning: Modifying your registry can cause serious problems that may require you to reinstall your operating system.
Always backup your files before doing this registry hack.

b. Navigate to the following registry keys and verity that following settings set to default:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableTaskMgr"=dword:00000000

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects\LocalUser\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableTaskMgr"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\]
"DisableTaskMgr"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"DisableCAD"=dword:00000000

c. Reboot the computer.

Let me know if this help.

Regards. :cool:

Hopefully you don't have malware that disabled it; I had this problem before!
