Last week Microsoft rolled out three prerequisite updates to prepare users computers for the first service pack for Windows Vista. However, one of these updates apparently caused serious issues among some users, prompting Microsoft to quickly suspend automatic installations of KB937287 after customers complained that their PCs wouldn't boot up properly once the update had been applied.

For affected users who already received the update, the only solution is to reboot their computers, boot from their original Vista disc and restore their computer to a state several days prior. However, some users have reported hardware and hard disk problems after restoration.

Nick White downplayed the problem on the Windows Vista Team Blog, stating that only a small amount of customers were affected and only in unique circumstances. Microsoft is trying to look into what is causing this unrecoverable crash, and has yet to respond whether or not the blunder will impact its plans to start offering SP1 to users next month.
