Microsoft is struggling to find answers for people whose attempt to upgrade to Windows 7 has sent their machine into an endless reboot cycle.
Reports of the problem first began appearing on Microsoft's support forum on Friday, the day after the operating system was first released. According to the complaints, Windows 7 claims the upgrade has failed and that Vista will be restored.
However, when the machine reboots it offers the same error and reboots again in an endless circle. Despite numerous reports of the problem, it seems Microsoft is still no closer to an answer and tempers are becoming frayed.
