Kids-friendly Windows shell replacement

I'm looking for a Windows shell replacement, which should have the following features:

1. Kids-friendly and kids-proof. Just a list of icons for programs that can be executed, everything else should be hidden or password-protected.

2. Low resource usage. It is going to be used on a computer with 512MB RAM.

3. Windows XP compatible.

I've looked into different Windows shell replacements, like Rainmeter or Emerge Desktop, but they all seem to be overkill and made for a power user. I need something that is very simple and lean, to be used by an 8 year old kid.

Solution 1:

Something like lightstep or a bb varient might be a good start. Edit the menu to hide anything you don't need, add a dock of some sort and you're good.
