CrowdStrike bricking – how to boot into Windows

It’s a bad day for CrowdStrike. Machines are being bricked globally, due to a faulty CrowdStrike update. Here’s a recovery process. You’ll need physical access to this machine for this and it won’t be possible to do this at scale, sorry. I’m not sure to what extent this workaround disables CrowdStrike, so proceed with caution.

Power on the computer
Press F11 to enter recovery mode (on some machines, where the manufacturer has overriden this default, you may need to press F9 or F12)
Choose advanced repair options

Choose troubleshoot

Choose Advanced options

Choose command prompt

Choose account

Enter password

Enter commands:

del "C:\Windows\System32\drivers\CrowdStrike\C-00000291*.sys"
exit

Then choose continue

You should now boot into Windows successfully.
