I have a HP Mini 110 that runs XP that I want to restore to factory condition.
HP's come with a very easy way to restore to factory settings. During bootup, repeatedly press the F11 key, and your computer will boot into recovery mode. After backing up all of your files, select the option to perform a system recovery. This will start your recovery, and will reinstall Windows and restore everything on your computer to the way it was when HP shipped it. Note, that this method gets rid of all of your Windows files, as well as personal files. You NEED to backup everything that you want to move to the new version. If you want to restore your system to an earlier time, you can do the following: Go to: Start > All Programs > System Tools > System Restore. Choose a date and time, and then hit Next twice. This will restore your computer if you just started having trouble.
