Microsoft experts released a custom WinPE recovery tool to find and remove the faulty CrowdStrike update.

To resolve the fix, admins needed to reboot impacted Windows devices into Safe Mode or the Recovery Environment and manually remove the buggy kernel driver from the C:\Windows\System32\drivers\CrowdStrike folder.

However, as the organizations face hundreds, if not thousands, of impacted Windows devices, manually performing these fixes can be problematic, time consuming, and difficult. That's why Microsoft has released a custom recovery tool that automates the removal of the buggy CrowdStrike update from Windows devices so that they can once again boot normally.
