⚠️ Windows 11 Update Alert: This Patch Could Break Your PC – Here’s What to Do
A critical issue has emerged with the latest Windows 11 security update, and it’s serious enough to put your data and device at risk.
Users are reporting:
- 💥 Hard drive failure and unrecoverable data loss
- 💻 Sudden blue screens of death (BSOD)
- 🔐 BitLocker screens locking them out — even if BitLocker wasn’t enabled
This was part of a recent automatic update from Microsoft, and it has now received a CVE severity rating of 9.8 – meaning it’s both widespread and dangerous.
✅ Are You a DarkHorse Patch Management Client?
Good news – you’re already protected.

- After the script runs, restart again to complete the process.
We’ve got your back.

🔧 How to Prevent Windows from Reinstalling the Problematic Update
Step 1: Pause Updates Temporarily
- Open Settings > Windows Update
- Click “Pause updates for 1 week”
