Those of you who are old enough to have used Windows98, lo those many years ago, may remember a utility called 98 Lite. This utility did what Microsoft said couldn't be done. Namely, it split Internet Explorer and a bunch of other embedded programs from the underlying operating system.
There is now a version for Windows XP SP2 (also works with Win2K SP4) called XPLite/2000Lite. This utility can give you back the power to pick just what is installed on your Personal Computer or at least it gives you the choice to install about 120 different Windows components.
Obviously, if you want an operating system that can do a variety of work you might not want to remove very many of those components but at least it's up to you decide. In addition, there may be times that this could act as an aid in troubleshooting problems by systematically removing components until the problem disappears.
If you need such a program, you can give it a free, limited function, test drive and see it it fits your needs. If it does, it'll cost you $40 bucks to download a license for the full monty and $10 more if you want the shiny disk edition. YMMV. Use at your own risk. The door is a jar. Objects are closer then they a pear.
Have a Great Weekend, Everyone - Aloha!
