How To Manually Forcibly Uninstall Cylance Protect

For example, in one such case we read about recently, the company was hacked and their Cylance tools were destroyed… that is a good time forcibly uninstall Cylance from all the desktop computers and servers so you can start again.

    3. Click the ADVANCED button
    4. Click the OWNER tab
    5. Change it to from SYSTEM to a DOMAIN ADMINISTRATOR
    6. Select “Replace owner on subcontainers and objects
    7. Click OK In the Security Tab;
    8. Click on Administrators Enabled Full Control for Administrators;
    9. Click OK to finish

Now you can change their special keys that lock Cylance:

  1. Delete the “LastStateRestorePoint” Key
  2. Right click and add a new DWORD32 key into HKLM > SOFTWARE > Cylance > Desktop named “SelfProtectionLevel” and set the value to 1
  3. Reboot the computer

Now you can manually uninstall Cylance:

  1. Start SERVICES.MSC
  2. Stop the Cylance service
  3. Open an elevated Command prompt and run:
    msiexec /x {2E64FC5C-9286-4A31-916B-0D8AE4B22954}
