KB5078167 Hotfix with two updates for Windows 11 Enterprise LTSC 2024
Microsoft just pushed out another update for Windows 11 Enterprise LTSC 2024, specifically targeting issues on builds 26200.7634 and 26100.7634 (that's KB5078167). This "out-of-band" fix wasn't part of the regular cycle.
One big thing fixed in this update involves Remote Desktop connections. For some users, logging into a remote machine used to fail completely; sign-ins were nixed. Now that's patched up, though. If you're trying to connect remotely and hitting trouble at the login screen, things should work properly again. The authentication headaches for various Remote Desktop apps are gone.
There's another problem addressed here too: some users reported crashing or weird errors popping up after installing updates around January 13th of this year. This happens when trying to open files from cloud storage, like OneDrive or Dropbox. Apps would freeze solid and refuse to reopen sometimes, especially if you'd set up Outlook to manage PST files stored on OneDrive. That could lead to needing a hard restart just to get your emails back.
The fix also covers the more general issue of unexpected application errors linked to those later cloud updates, smoothing things out when interacting with services like OneDrop or Dropbox from Windows itself.
