Windows XP Activation Algorithm Has Been Cracked
Liam Proven, reporting for The Register: Over 21 years after it first came out, the Microsoft operating system that will not die is receiving another lease of life. It’s possible to activate new installations, safely and securely, without a crack, off line. A blog post on tinyapps has revealed the hot news that nobody sane has been waiting for: the algorithm that Microsoft uses to validate Windows XP product keys has been cracked and reimplemented. As a result it’s now possible to generate valid activation codes for Windows XP, without an internet connection, even though Microsoft has turned off all the activation servers.

This is not a recommendation
But first, a word of caution and restraint. Please don’t take this article as a recommendation to run Windows XP. It wasn’t the most secure of operating systems back in 2001, and you really should not be running it in 2023 — especially not on anything that is connected to the internet. However, saying that, the problem is that sometimes people need to. There is, for example, hardware out there that only works with Windows XP and won’t work with anything newer… and some of it might be very expensive hardware, which is still perfectly functional — but which requires a long-obsolete version of Windows to operate it. If you are lumbered with such a device, or you have got some single specific and very particular piece of software that you need to run and which doesn’t work properly on any newer version of Windows, then you may be forced to use XP. If so, one of the problems is that Microsoft has turned off the activation servers, so even if you install clean fresh copy, you can no longer activate it over the Internet. (Allegedly, the telephone activation service still works, if that’s an option for you.)
