The purpose of those popups is a special "Fuck You" to Europe for enforcing privacy rules. They make it painful on purpose, out of spite.

I'm so sick of these worthless fucking techbro responses to regulation.

Updating individual machines is a long manual process:

The file in question is a CrowdStrike driver located at Windows/System32/Drivers/CrowdStrike/C-00000291*.sys. Once it's gone, the machine should boot normally and grab a non-broken version of the driver.

Deleting that file on each and every one of your affected systems individually is time-consuming enough, but it's even more time-consuming for customers using Microsoft's BitLocker drive encryption to protect data at rest. Before you can delete the file on those systems, you'll need the recovery key that unlocks those encrypted disks and makes them readable (normally, this process is invisible, because the system can just read the key stored in a physical or virtual TPM module).
