When you open My Computer, by default XP will search for network files and printers. This slows down the display of the icons while the search takes place, especially on a slow machine. You can speed this up by telling XP not to perform this search. Here’s how:
1. Click Start | My Computer.
2. Click Tools | Folder Options and click the View tab.
3. Uncheck the checkbox that says “Automatically search for network folders and printers.”
4. Click OK.
Now when you open My Computer, the icons should display faster.
