Unstrike can automatically rescue a Windows 10 or 11 installation that has been affected by the 19 July 2024 CrowdStrike Falcon content update error. This tool will create a new ISO file that can be copied to a USB drive using software such as Rufus. All you need is an ISO image of Windows 10 or Windows 11.
It’s important to know what’s running with high privileges in your network, which is why Unstrike is designed to be auditable. It makes use of a PowerShell script and the mkisofs program. Please review the script before executing it, to ensure it meets your needs and has not been compromised. It is also signed by Hashbang Productions, the developers of Legacy Update, and many other open-source projects.

The PowerShell script is signed. If you want to quickly determine whether the script is safe to run, you can review the Digital Signature tab in the file properties.
The copy of mkisofs.exe included in the repository comes from VMware Workstation, as this was an existing signed binary that was readily accessible, and I feel this should be trustable as being safe and unmodified. The binary is signed by VMware, Inc., and can be reviewed on VirusTotal.
