Many computers have experienced endless reboots after installing Windows XP’s SP3 according to posts at Microsoft’s support forum.

“I just installed Windows XP SP3 and after completing the processes and when the system reboots, the system cannot proceed to load the Windows. It just displays the flash screen of Windows then after it reboots again,” said a user named “Olin” in one of the posts.

The users reported that they cannot go into Windows Safe Mode or revert to a previously saved System Restore point.

The IDG.no article notes that Microsoft was not available for comment early Friday.
