how to disable and enable
the control panel in windows OS:
Step 1: Go to Run prompt, enter 'gpedit.msc' (without quotes) and click OK. Note that this might require administrator level elevation.
Step 2: The Local Group Policy Editor will now be opened up, having a dual-pane interface. In the left pane, navigate to User Configuration > Administrative Templates > Control Panel.
Step 3: Now in the right pane, double click on the 'Prohibit access to Control Panel and PC settings' option. Once the configuration box opens up, use the radio buttons on the top left corner of the box to change the setting's value from 'Not Configured' to 'Enabled'. When done, click OK and close the Local Group Policy Editor.
You've successfully disabled Control Panel in Windows. Going forward, whenever someone tries to access Control Panel, they'll be greeted with an error message saying that the operation has been cancelled due to restrictions in effect on the computer.
It's also worth noting that the above method also removes the system links of Control Panel from locations such as Windows Explorer. To enable access to Control Panel again, follow the same steps as above and in Step 3 change the setting back to 'Not Configured'.
