Overview

Third-party backup applications rely on Windows APIs, libraries, drivers, and system frameworks. These components evolve through monthly cumulative updates, optional preview releases, out-of-band patches, and annual feature updates. Recent Windows 11 changes, particularly in kernel-mode driver validation, Code Integrity enforcement, and the Vulnerable Driver Blocklist, have affected the normal operation of backup software.

Because backup tools depend on stable low-level system behavior, even minor Windows modifications can lead to functional regressions or driver-loading failures.

Recent Impacts After Windows Updates 📣

There have been some significant impacts on backup programs from recent Windows Updates. Not all programs are affected by the each of these issues.

Vulnerable Driver Blocklist Expansion

Microsoft expanded the Windows Vulnerable Driver Blocklist to include psmounterex.sys, citing multiple high-severity vulnerabilities and a previously documented buffer overflow condition. Blocked drivers cannot load, which may disrupt backup or restore operations.

Enhanced Kernel-Mode Driver Validation

New validation rules for kernel-mode drivers have caused some previously accepted third-party drivers to fail during initialization, resulting in backup failures or degraded functionality.

VSS (Volume Shadow Copy Service) Hardening

A regression in VSS behavior has been observed following certain updates. This may cause snapshot creation to fail or time out, directly affecting backup creation.

Framework and Security Model Adjustments

Changes to Windows internal frameworks, access control models, and security boundaries have affected how backup applications interact with protected system components.

LanmanWorkstation Service

Windows changes to this service may impact bare-metal restores from backup programs deployed in WinRE that use SMB.

Roll Back the Windows Update

If the issue is confirmed to be update-related, use Windows' rollback functionality to revert to the previous version.

Restore a Pre-Update System Backup

If necessary, restore a system backup created prior to the problematic update. After restoring, pause Windows Updates until Microsoft or HBS provides a resolution.

Wait for a New Windows Update

If the problem is not critical, wait for it to be resolved.

Frequently Asked Questions 🔥

Conclusion

It is recommended, after each Windows Update, that stability of the system should be checked.

Verify the HBS Boot Menu and Emergency Disk (ED)

Confirm that both can:

• Boot successfully into the recovery environment
• Connect to Wi-Fi (if applicable)
• Access backup storage locations

Verify the Mount Feature from HBS Running in Windows

Confirm that HBS running in Windows can:

• Access backup storage locations
• Successfully mount a backup image
