You may want to reload windows for several reasons. Our caller had several files that always came up missing in his system. If the missing files are application specific - In other words, if the error only occurs when you open Microsoft Word, Excel or other program then you may want to just reinstall that application. Restart and test to see if you are getting the same error.
Our caller wanted to know if he had to delete his old copy of Windows XP before installing.
No. You can install Windows XP over Windows XP. Note: Windows XP also has a repair feature, but if you are missing files it probably won’t fix the problem.
Reinstalling Windows does not delete other programs or documents. The only time this would occur is if you reformatted the hard drive. It is always a good idea to back up your document and configurations before reinstalling. Make sure you have your install Key Code before you start installing. You’ll be rebooting off of the CD.
Don’t forget to back up your emails and contacts. Here is a great tip on how to save your documents, emails and internet settings:
Tip: There is a Utilities Tool that you can use to help back up your documents.
It is called Files and Settings Transfer Wizards. It will back up your documents, internet favorites and email.
You get to it by going to Accessories / System Tools / Files and Settings Transfer Wizards
It will create one file that you can now back up to an external drive or CD.
After you install XP you run the Files and Setting Transfer Wizard again and find the files from the external hard drive or off of the CD you created and you’ll have your settings back on your machine.
Our caller also asked: Is it good to periodically reinstall Windows? No. If your computer is running smoothly there is not need to.
