Windows Reactivator

Windows Reactivator is a lightweight and portable application that enables users to backup and restore the activation status of their Windows XP copy. It is very simple to use, even by individuals with limited or no experience in software programs.

Since installation is not a requirement, you can just drop the executable file somewhere on the hard disk and click it to run. It is also possible to move Windows Reactivator to a USB flash drive or similar storage unit, in order to run it on any workstation with minimum effort, as long as it has Windows XP installed.

An important aspect to keep in mind is that the Windows registry does not receive new entries, and leftover files not kept on the hard disk after removing the program. A standard file deletion is suffice to accomplish this task.

The interface is based on a small, regular window with a WYSIWYG layout, where all you have to do is point out the saving directory for creating a backup as well as for the wpa.dbl file location when restoring it. Windows Reactivator automatically carries out the task in no time.

The straightforward piece of software runs on very low CPU and RAM, so it doesn't hog system resources or affect the computer's overall performance. No error dialogs have been shown in our evaluation, and the tool did not hang or crash. Unfortunately, Windows Reactivator does not provide additional settings.
