I would hope that MS has a un-do for the ‘patch’..................
All you need to do is boot up from the install DVD or USB stick, and then apply the recovery snapshot from the OS.
When you boot up to recovery from the install media, it is actually running Windows PE on a RAMDisk, so the original hard drives and OS are exposed for operations to recover, like finding the restore point snap shot and reapplying it to the operating system.
It would be like a new install with your data restored from the time you took the snap shot, minus the patch that caused the bricking.
