Last week, I showed you how to create your own minimal XP install for the Acer Aspire One using nLite. By following my config, you should be able to shave somewhere between 300 and 500MB off of your stock SP3 Windows XP install. By doing this alone, you should have a pretty minimal fresh install of XP as a lot of unnecessary programs are already cut out, saving a few background processes along the way.
However, there are a few more tweaks we can do to your freshly cut down XP install to make it even less resource intensive. I’ll show you which background services and processes I have found pretty safe to disable, resulting in a super-minimal install and configuration of Windows XP.
