If you right-click on This PC icon on the desktop or This PC in the navigation pane, you will see a context menu.
In this menu you will see the Manage option, which is to open Computer Management.
If you do not want this option, you can remove it by following these steps:
Extend the following key: HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Policies.
Press the Explorer key.
If you do not see the Explorer key, you need to right-click on the Policies key and choose New > Key, enter Explorer, and then press Enter.
On the right, search for NoManageMyComputerVerb.
If you can’t find it, create it. Here’s how: Right-click on the space in the right pane, select New > DWORD (32-bit) Value. Provide the name as NoManageMyComputerVerb and then press Enter.
Double-click on NoManageMyComputerVerb. In the Value data field, provide the value 1.
Press the OK button. Restart your PC or File Explorer.
That’s all. Manage will no longer be in the context menu.
Note: If you want this option, delete the DWORD created above or replace 1 with 0.
Navigate to User Configuration > Administrative Templates > Windows Components.
Press File Explorer.
In the right pane, you will find “Hides the Manage item on the File Explorer context menu.” Double-click on it.
Select Enabled and click OK.
That’s it. To restore this option, follow the steps above and choose Not Configured or Disabled.
