If you're using the official release of Windows 8 Enterprise trial, you'll need to activate it. PC Settings doesn't have an entry to Activate, so you'll need to go to the Desktop to do so. The little Action Center icon on the lower right hand side (a little flag) should have a red X. Click on it, and it should say you need to activate. Do so, and you'll get those customizing features unlocked.
same here problem is when i click in pc setting and personlise to change the start up screen then whole options like 'browse' etc is covered in semi white layer and canot be clicked any where . so what is the problem help
I had the same problem on another system. I looked for driver Windows 8 updates for the video card and could find none. So just as a test I took the video card from another computer running Win8 and replaced it. I was then able to change the settings, they were nolonger "faded out".
So I'd suggest replacing the video card or see if the drivers can be updated.... Worked for me....
