If you’ve been pulling out your hair lately as your Windows 11 24H2 or Windows Server 2025 suddenly decided to treat Remote Desktop sessions like an unsupervised game of freeze tag, good news: the un-chill is finally over.

Microsoft’s RDP Freeze Drama: Now Thawed​

Here’s the scoop. Earlier this year, a spicy combo of the February security update (KB5051987) and its friends sent certain Windows Server 2025 and Windows 11 24H2 systems into a state of frosty despair. Users, eager to hop into those RDP sessions, found themselves staring at frozen screens, their keyboard and mouse utterly unresponsive—unless, of course, you count the frantic jabbing of Ctrl+Alt+Del as a form of athleticism.
What made this bug particularly vexing (aside from the “Groundhog Day” style disconnect-reconnect ritual) was its timing; admins and IT folk had hardly finished the coffee runs for Patch Tuesday before this popped up. Microsoft, diplomatic as always, acknowledged the problem in their Windows Release Health Notes—so no, you weren’t imagining things.

Melting the Ice—At Last​

Thankfully, spring has come for our afflicted servers and desktops. Microsoft’s April fix (KB5055523) for Windows Server 2025, and an earlier fix via end-of-February’s KB5052093 for Windows 11 24H2, have been released into the wild. The instructions could not be more straightforward: install the latest updates. The implicated RDP sessions should finally behave, and administrators everywhere can breathe out like they’ve just survived a surprise Blue Screen at a board meeting.

Spot the Subtle Difference​

Interestingly, the timeline for the fix dances a little between operating systems—Server 2025’s nightmare began with February’s update, while Windows 11 24H2 users felt the freeze after January’s update preview. But the plot twist? Windows 11’s salvation arrived a month ahead. If only our commutes operated on Microsoft’s bug-fix schedule.

Update Error 0x80070643: The Phantom Menace​

Of course, what would a Patch Tuesday be without a bonus round? Enter error 0x80070643—an “ERROR_INSTALL_FAILURE” post-update message popping up on Windows 10 22H2/21H2 and Server 2022. Take heart: this error is basically that one ghost story your uncle tells at family gatherings. Microsoft assures us it’s all smoke and no fire—the update and your device are just fine. The KB5057588 update for the Windows Recovery Environment triggered this “fake news” error, but it doesn’t actually break anything. Now if only our printers were so forgiving.

Critical Analysis: Too Many Cooks in the Update Kitchen?​

While it’s a relief to see Microsoft responding with agility (and an impressive array of KB numbers), these recurring hiccups with updates are the IT equivalent of getting socks for Christmas—you appreciate the effort, but could we please get socks that fit? Each misfiring update shakes the faith of IT pros already on high alert for the next zero-day.
The transparency in health notes is commendable, but users yearning for a calm patch experience may feel like they’re stuck in a Shakespearean tragedy. Today’s freeze bug eventually becomes tomorrow’s update error, ad infinitum. Microsoft’s advice remains simple: keep calm and update on—just maybe after triple-checking the Release Health dashboard and brewing another pot of coffee.

Final Thoughts: Patch, Reboot, Repeat​

For all the drama, Microsoft has, at least, cut off this latest RDP misadventure at the knees. If your servers or desktops have been feeling a bit glacial, trust the April update to bring the thaw. And if you encounter a phantom error code, remember: sometimes the error’s bark is worse than its bite.
One thing’s certain: In the Windows world, there’s never a shortage of excitement come update season.
