The "problem" you are having with your "specific" questions are that while they may be "specific" they don't show that you have done any research on your own. LS is NOT a hand holding community. You will have to put your own time in and learn on your own.

The problem you were having with Windows Update is caused by Windows Update actually being part of the Explorer Shell. M$ was dumb and you have to pay the price for it with LS. You can get it to work with the write settings; but those settings should only be used by those that know what they are doing...and you don't know what you are doing yet.

As for your Favorites and Documents and all that other crap from the Start Menu...those are easy enough to do and a simple look through the docs will get it done. However, I will tell you now that LS won't update the information in them so I really hope the docs that you had used recently is what you want to see for all eternity.
