"A required privilege is not held by the client". What does THAT mean?

HOW TO GIVE YOUR SELF ADMINISTRATIVE CONTROL OVER YOUR OWN COMPUTER
1. Put your mouse to the corner of your computer screen to make the charms things appear and click on "Start Tile".
2. Right click at the bottom of you screen and an "All Apps" icon appears. Click it.
3. Scroll over to the right till you see "Windows System" Tile. Right click on "Command Prompt". Then at the bottom of the screen you will see an icon that says "Run as Administrator". Click that and a black window pops up. Thats where you need to type in your command that will give you Administrative Control.
Here is what you copy and paste into the command:
net user administrator /active:yes
Something should appear on the black box, telling you that the command completed successfully.
You will have to then restart your computer. Now when you restart your computer you will see two squares, one will be your old square with whatever your name is that you normally log in as, and the other will be the Administrator square. And of course, if you want to log in as the Administrator you would just click that square. It will act like when you first clicked your other square, except it wont go through so much of the rigamarole as it did before. You will have to add a few of the things back onto your computer like you did when you first got it, but most of the stuff will still be there to access. So make sure you have it written down where you downloaded your programs at before so that if you have to you can download them again.
But you can always restart and just click on your old square/tile again and log in like you used to, not as the Administrator, if you need to get back some of your old stuff to put onto your new Administrator "computer". At least this way you will be able to gfet rid of the "You need permission to..." problem. Just dont mess with any of the System Files or Program Files on your computer like NVIDIA or in the System Folder, and you will be alright. And it will work just like on Windows XP or whatever program you used to have.
Now, whenever you want to change back and forth between your old account and your Administrator account:
Control/Alt/Delete click on "Switch User".
*Now I just have to find out how to KEEP it on the Administrator Account all the time.
And just an addtional tip. If you want your Windows 8 to work more like your Windows XP did, please install Windows Classic Shell so it will be just like your old Start button again.

And if you want to be able now to get rid of the "Charms" Bar or at least disable it (you can enable it back again if you need it), now that you have the Windows Classic Shell, its easy to do that.
Get rid of the Charms Bar. Right Click your Classic Shell Start Button then click on "Settings". Make sure that "Show all Settings" is checked. Then click on "Windows 8 Settings". Tick the following radio buttons: Skip Metro Screen, Disable Active Corners-ALL, Disable Taskbar Transparency.
This will help get rid of most of the maddening features of Windows 8 and make your computer more "normal" again.
