Microsoft September Update May Crash Your Windows File History Backup – What Small Businesses Need to Know

What Happened?

Microsoft released the September 2026 security updates for Windows 10 and Windows 11. After installing these updates, the built‑in File History backup feature can stop working on some computers. The issue appears when the update changes how Windows accesses external drives, causing File History to lose its connection and stop saving new backup copies.

Why It Matters to Small Businesses

For small businesses, losing automatic backups can mean:

• Data loss – critical files, invoices, and client records may not be backed up.
• Downtime – restoring files from older backups takes time and can interrupt operations.
• Compliance risks – many industries require regular data protection; a broken backup could violate policies.
• Increased cybersecurity exposure – without recent backups, ransomware attacks become far more costly.

Steps to Protect Your Data

Take these immediate actions to keep your files safe:

• Verify backup status – Open File History settings and confirm the last successful backup date.
• Pause the September update – If the issue is confirmed on your system, temporarily defer the update until a fix is released.
• Switch to an alternative backup solution – Use cloud storage (OneDrive, Google Drive) or a third‑party backup program.
• Test restore points – Ensure you can recover files from an older backup before relying on the new system.
• Schedule regular checks – Set a monthly reminder to review backup health.
