Microsoft has released the Windows 10 KB5087544 cumulative update as part of the May 2026 Patch Tuesday rollout, bringing security fixes and stability improvements—most notably addressing issues affecting Remote Desktop (RDP) connections. Which is welcomed news for the large base of Windows 10 users who have either skipped the upgrade or are using a system that isn't eligible.
The update is part of Microsoft’s ongoing effort to improve reliability after a series of recent Remote Desktop changes introduced new security protections across Windows 10 and Windows 11 systems.

The KB5087544 update focuses on resolving bugs that impacted Remote Desktop usability, including:
- Fixes issues where RDP sessions could freeze or disconnect unexpectedly
- Improves handling of RDP security warning dialogs
- Resolves problems with authentication prompts not displaying correctly
- Enhances stability for multi-monitor Remote Desktop sessions
These fixes help ensure smoother remote access for both home users and enterprise environments.
🛡️ Security Improvements Included
Alongside bug fixes, the update strengthens protection against malicious activity using Remote Desktop files.
