Forcing Windows XP to register causes problems
It looks like Microsoft made a mistake in the Windows XP registry, which is mandatory. So some owners of the said operating system cannot register at all. But a solution is being worked on.
Some users who have ordered the new Windows XP operating system from Amazon cannot register their copy because the corresponding license is already being used several times. Similar problems also occurred with CDs that are supplied with Aldi notebooks. Microsoft is currently investigating one of the packages. But the cause has not yet been found. Affected customers will still be able to register their installation because Microsoft will activate the corresponding licenses.
