Windows Xp Legacy Update 🎁 🎉

To understand why this tool is brilliant, you have to understand the state of Windows XP today. Since Microsoft ended support in 2014 (and removed the active update servers later), installing Windows XP from a disc leaves you with a time capsule.

    If you are a hobbyist: go wild. Install KEX, try the unofficial Service Pack 5, join the MSFN.org forums where the developers of these tools post daily.
