Microsoft's upcoming Windows 11 24H2 update is facing unexpected compatibility issues with certain USB scanners, leaving businesses and home users searching for answers. The problem stems from a security feature called SENSEHIDELIGHT in the kernel-mode driver sprotect.sys, which is causing system crashes during scanning operations.

The Core of the Problem

The issue primarily affects USB scanners that rely on older driver architectures. When users attempt to scan documents after installing the 24H2 update, they encounter:

  • Blue Screen of Death (BSOD) errors
  • Complete system freezes
  • Failed scanning operations
  • Event Viewer logs showing sprotect.sys failures

Microsoft has confirmed the problem through its Windows Health Dashboard, stating: "After installing KB5039302, some devices might experience issues when using certain USB printers/scanners."

Affected Devices and Workarounds

While Microsoft hasn't published a comprehensive list of affected scanners, reports suggest these brands are most vulnerable:

  • Older Canon DR and imageFORMULA models
  • Certain Fujitsu ScanSnap units
  • Some Epson WorkForce scanners
  • Select HP OfficeJet all-in-one devices

Temporary solutions include:

  1. Using manufacturer-provided WIA or TWAIN drivers instead of Windows native drivers
  2. Connecting via network instead of USB where possible
  3. Rolling back to Windows 11 23H2 until a fix is available

Why This Matters for Enterprise Users

For businesses relying on document scanning:

  • Medical offices using patient record systems
  • Legal firms processing large document volumes
  • Financial institutions handling check deposits
  • Government agencies with archival workflows

The disruption could significantly impact productivity. IT administrators should:

  • Test all scanning equipment in a controlled environment
  • Prepare fallback solutions
  • Monitor Microsoft's update channels closely

Technical Deep Dive: SENSEHIDELIGHT

The root cause appears to be Microsoft's SENSEHIDELIGHT security feature, part of their ongoing efforts to:

  • Prevent driver conflicts
  • Block malicious USB devices
  • Enforce memory protection

Unfortunately, this security measure is incorrectly flagging legitimate scanner operations as potential threats. The sprotect.sys driver then terminates these operations abruptly, causing system instability.

What Users Should Do Now

  1. Check your scanner model against manufacturer advisories
  2. Delay 24H2 deployment if scanning is mission-critical
  3. Contact support if you experience issues
  4. Monitor Windows Update for the compatibility patch

Microsoft has stated they're working with hardware partners to resolve the issue before the 24H2 update's general availability, expected in September 2024.
