ซ่อน Control Panel

1) Access your Group Policy Editor: Start > type gpedit.msc in the Search Bar
2) Access the Control Panel options: User Configuration > Administrative Templates > Control Panel > Hide Specified Control Panel Items / Show Specified Control Panel Items
3) Enable the feature
4) Add the name of the item you wish to hide or show: Click on Show, then Add the names of the icons you wish to hide or show. You must enter it exactly the way it is shown in the Control Panel (case-sensitive.)

5) Click Apply and OK. No reboot required.
I’ve always wondered why the control panel has load time. If anybody knows, please leave a comment.Was I able to help you? If you still have a question, click here and I will get back to you with an answer.
