General Sentiment
This update presents a mixed reception profile. On the positive side, it delivers important security fixes and reliability improvements for critical system components like BitLocker. However, the update has introduced notable compatibility issues that affect user workflows. The security hardening for folder customization has caused some users to experience missing custom folder icons and localized folder names, though folder access remains unaffected. Additionally, a significant issue prevents certain third-party applications from launching Microsoft Office applications, impacting users of popular software like CCH Engagement, dental practice management systems, and Zotero.
Known Issues
- Microsoft Office applications might fail to open from certain third-party apps (affects CCH Engagement, Workpaper Manager, dental software like Dentrix and Softdent, Zotero, and similar applications using OLE automation)
- Deleting from Recycle Bin displays internal file name (e.g., $Rxxxxx.ext) instead of original file name in confirmation dialog (resolved in KB5095091)
