xpmgr

Command line interface for Windows XP license management, inspired by Microsoft's "slmgr".

Usage

You need to download the right version for your edition of Windows XP/2003!

In most cases, you'll need xpmgr_x86.exe.

If you have Windows XP Professional x64 Edition or a x64 version of Windows Server 2003, you need xpmgr_x64.exe.

If you have an Itanium version of Windows XP or Server 2003, Windows Product Activation is not on those editions, so there is no need for this tool.

/dli: Gets the product ID (ex: 76477-755-3803223-21229).

/ipk: Sets the product key (tested to work with dashes). If already activated, this should give an error instead.

/dti: Gets an Installation ID with no dashes (ex: 253286028742154311079061239762245184619981623171292574). If already activated, this should give an error instead.

/atp: Sets a Confirmation ID (tested to work with dashes). If already activated, this should give an error instead. If successful, this also removes the "Activate Windows" shortcuts and kills the WPA notifier process (wpabaln.exe) if it's running.

/xpr: Gets the number of days before activation is required, in days. If already activated, this should give an error instead.

/xpr-eval: Gets the number of days before the evaluation period expires, in days. In non-evaluation copies of Windows, this should give an error instead.

/?: Outputs all the commands you can use.
