When changing my expired login password, using Windows XP, it won't let me reuse my same password. Says I can't due to previous history use. How can I get around this so I can re-use my password. Is there a way to set the password so it won't expire?

Do you know the number of passwords that have been stored and how long they are valid for ?

Is this a stand alone PC or a machine on a LAN. The only time I've seen an expiration on a PC is if it is attached to a LAN. In which case, the no repeat policy is set by the LAN admins,

If you can get to a command prompt, try this command (probably need to be run as administrator):
net accounts /maxpwage:unlimited

If by chance your running XP Professional and have your disk (XP Home won't work) you can do a non-destructive reinstall of the OS where you re-enter your serial and pass during the repair. It should reset everything. But there are negatives about it. One is your system files are replaced with the ones on the disk so you lose all the critical updates that are not included on the disk. If your disk is SP3 or has been integrated with newer critical updates it would be a lot better for you when you go to get your updates to date (which in itself can be a hassle these days). If your disk is SP2 you can attempt to slipstream SP3 and the critical updates onto the disk but that is not a walk in the park. A non-destructive reinstall replaces all system files from the disk without effecting the installed programs or their registry settings as well as all your data. You can read about it on the Langda letters web site.

You might also want to search some info on slipstreaming an XP disk and some of the sites that have collections of updates for you to integrate onto your disk. Basically you copy all the files from your disk to the hard drive and use commands to intregrate the new files to that folder and then make a new boot-able disk. There are also applications like nLite that simplify the process, but I don't know it they are still active or in use.
