I can do an upgrade of windows 10 Pro or Home 64 bit or 32 bit and in most cases windows 11 both flavors even on older machines however you may be required to upgrade some hardware IE RAM (memory). You will be given your lisc number, registered to you. I will need your info though for both the invoice and licensing! If this is a fresh install lisc fee's are extra and depends on which operating system you want. Contact me. I "might" be able to use your current sticker again lets be CLEAR "might".
