How To Explore the New Big Feature and Fixes in Windows 11 Build 27863 (Canary)

Introduction of Quantum Signature Algorithm Support

The latest Windows 11 Insider Preview Build 27863 for the Canary channel is pretty interesting. One of the main highlights is support for this post-quantum signature algorithm called MLDDSA. Basically, Microsoft is trying to beef up security in anticipation of future threats from quantum computers. If you’ve tinkered with cryptography before, you’ll know this is a big deal for security nerds. The addition of MLDDSA along with updates to Crypt32 is meant to ready Windows for whatever crazy security challenges lie ahead.

New GIF Creation Feature in Snipping Tool

Another feature that caught a lot of folks’ attention is the ability to make GIFs right from screen recordings using the Snipping Tool. Yeah, you read that right. Instead of hitting up some third-party app to make GIFs, now you can just do it within Windows. The shortcut to access this is Ctrl + G, which makes it feel kinda quick and slick. You can select the quality and see size info before exporting, so it’s pretty handy for quick clips — think content creators, educators, or just someone who wants to make fun quick GIFs without messing around with complicated software. But fair warning — sometimes the GIF creation process can be a tiny bit flaky, especially on older hardware or if Windows is feeling particularly sluggish that day.

Fixes and Improvements

Of course, with every new build, there are fixes. This one rolled out some pretty important ones, like:

• Fix for Windows Sandbox crashing with error 0xc03706 — because nobody wants their sandbox failing to launch when they’re all set to test stuff.
• Problems where core parts like File Explorer and Start Menu just refused to load in safe mode? Resolved. Finally.
• A fix for crashes caused by msftedit.dll related to apps like Sticky Notes and Dxdact if your display language is Hebrew or Arabic. Because of course, Windows likes to make things harder than necessary.

If you’ve been running into those issues, check if this build helps. Usually, these fixes translate to a smoother overall experience, but sometimes, you’ll need to reboot a couple of times or clear the cache to see the full effect.

Known Issues to Keep an Eye On

Not everything’s perfect, though. One irritating bug that’s still hanging around is that the Task Manager search bar is kinda dead — no matter what you try, it doesn’t work. This has been a thing for a while now, and if you’re relying on that search function daily, yeah, it’s a pain. Hopefully, Microsoft sorts this out soon. On some setups, the task manager itself may also stumble, so don’t be surprised if it’s not totally smooth sailing yet.

Conclusion

All in all, the update has some solid new stuff like the GIF feature and security improvements. The fixes make Windows a bit more stable, but a few bugs still linger. Not sure why it works, but these preview builds can be a bit unpredictable, so it’s always good to keep a backup before installing. Keep an eye on future updates, because the Windows team is always tweaking stuff in these early builds. On one setup it worked fine, on another, not so much. Typical Windows stuff, honestly.
