You've got that backwards.... twice. Your Thread title says:
and now you are saying:
How could i remove sufficient security privilegs to uninstall devices
So which is it? do you want to install or remove devices, or add programs, or, just what is it you want to do?
Hello,how could i remove sufficient security privilege to instal program?
Whatever it is, you don't go about it by removing privileges, that lets you do less and less.
If you are a member of the Administrators group, you can do almost anything. If you are a User, you are indeed limited and need your privileges elevated, not removed.
Determine what group you are in by clicking:
Start>Settings>Control Panel>User Accounts>
When it opens, you will see your log-on name in the little box and it will say what group you are a member of.
