Microsoft has confirmed that July's security updates break remote desktop connections in organizations where Windows servers are configured to use the legacy RPC over HTTP protocol in the Remote Desktop Gateway.
"Windows Servers might affect Remote Desktop Connectivity across an organization if legacy protocol is used in Remote Desktop Gateway. Resulting from this, remote desktop connections might be interrupted," Microsoft explained.
The second workaround requires editing the RDGClientTransport registry key under Terminal Server Client by going to HKCUSoftwareMicrosoftTerminal Server ClientRDGClientTransport using the Windows Registry Editor.
Two years ago, Microsoft had to fix a known issue causing RDP and VPN connectivity problems on Windows Servers with Routing and Remote Access Service enabled after installing the June 2022 security updates.
In January 2022, it also issued an emergency out-of-band update to address a Windows Server bug causing Remote Desktop connection and performance issues.
Windows July security updates send PCs into BitLocker recovery.
