Windows XP needs to activate, but than says already activiated.
I recently ran updates on one of my clients computers, and during the reboot after putting in their login crediantials windows said that it needed to be activated. After clicking ok, it just says windows is already activated and I was stuck at that screen. Tried everything to access this computer, but decided to just rebuild the computer. Now why would this have happen? I also ran magic jelly bean on other computers in the office, and they are reporting different keys than the stickers on the computer. Their reporting SLP OEM Keys, which were found using google. Why would someone use SLP OEM Keys? Is it ethical/legal? Are you able to run updates on SLP OEM Keys?
Thanks.
Thanks.

# OEM:SLP (System Locked Pre-installation): OEM SLP keys are preinstalled by the OEM on the machine. End-users normally does not get to see the product key, unless when using product key viewers to retrieve the key manually. Data embedded in the BIOS (in SLIC table), together with the digitally signed certificate (OEM cert), is used to validate the product key. SLP keys will work with any OEM SLP system, regardless of the OEM systems brand, i.e. not brand specific.
OEM SLP product keys are the only keys that are able to perform offline activation instantly and locally, without going online or connecting to Microsoft server. OEM SLP keys are only issued to big manufacturers such as Dell, Asus, Sony, etc.
# OEM:NONSLP (Non System Locked Pre-installation): Similar to retail product key, but distributed and supported by an OEM. Non-SLP product key is also not brand specific. End-users are required to perform activation by phone or activate online.
# OEM:COA (Certificate of Authentication): The OEM:COA is normally provided via a COA sticker pasted on the casing (side or bottom body) of new desktop, notebook, laptop, netbook or nettop PC, which has already been activated with a pre-installed OEM:SLP key by OEM.
Contrary to popular belief, the product key printed on the COA sticker is not used to activate the Windows, its master SLP royalty key that does the job. COA product key is provided as it would be required if a reinstallation of Windows is needed, unless users backup OEM activation beforehand. End-users are required to perform activation by phone or activate online.
