Hi Char, In Windows XP it's called "Check Disk". Open My Computer or Windows Explorer, right click the "C:" drive and select "Properties". In the Properties window click on the "Tools" tab. There are three options there with "Error-checking" listed at the top. Click the "Check Now..." button. The Check Disk window will appear. Check the two options and click the "Start" button. An information window will appear telling you it can't check it now because it needs exclusive use of some Windows files and it can only be done on a restart of Windows. Then it asks if you want to do it the next time you restart the computer. Click "Yes". In the Windows Task Manager, the Applications tab shows those programs and applications that you have open and are working with. For example, at the moment mine shows Outlook Express and this draft e-mail. All other programs and processes will appear on the "processes" tab.

Hello. Can you tell me how to run thorough scan disk on Windows XP? Also, when I hit control - alt - delete to see all of the programs running, only one or two are shown, when I know there are many more programs running. Why is that? I appreciate your help.
