On March 8th, 2014, Windows XP customers using the Home or Professional editions who have elected to receive updates via Windows Update will receive an official notification on their desktop screen via Windows Update informing them that support for Windows XP will end on April 8th, 2014.
Please note that this pop-up only goes to consumer (unmanaged) Windows XP PCs. For those PCs affected, there is no “XP Blocker Toolkit” nor is there a registry key that can be set to block the update, however a single click on the checkbox will disable it forever. If the computer is managed by WSUS, it will not by default receive the pop-up.
Additional details on this message:
- The pop-up will recur monthly (on the 8th of every month at 3:00 p.m. local time, and the code will continue to show the message on this schedule indefinitely or until the user disables the notification)
- If the user is not logged in during the scheduled time, the message will be shown the next time s/he logs in.
- If there are multiple user accounts on the machine, the scheduled task is tied to the user who is logged in when the update is installed and only he/she will see the notification.
- The notification will direct customers to this end of support web page:
