But Microsoft had a bit of an "oopsie" with the most recent Update Tuesday, formerly known as Patch Tuesday. In some computers, the newest update can cause the Blue Screen of Death, effectively bricking your computer.
Don't panic, there is a specific set of elements that's needed to create the perfect storm for the Blue Screen of Death. The kernel update, named MS 14-045, has been pulled by Microsoft, so if you still haven't updated from the last Update Tuesday, you should do so now.
The Blue Screen of Death happens when the update kernel incorrectly handles the Windows font cache file. This happens during the boot-up part of the update, so you're stuck in a reboot loop.
If you have been affected by the update, you'll see the Blue Screen of Death but you'll also see the bugcheck number "0x50 PAGE_FAULT_IN_NONPAGED_AREA."
