Microsoft tells users not to install their own update

The February preview update failed to install so spectacularly that Microsoft officially told users not to install it. Installations failed with errors 0x800f0922, 0x800f0982, and 0x80070002, rolling back at 96% completion — tantalizingly close to success before crashing back to square one. The workaround was to manually delete a hidden C:\$WinREAgent folder, because of course the fix for a broken Windows update is to dig around in hidden system directories. When the company that made the update publicly advises against installing the update, you know quality assurance has left the building.
