Known Issues SMBDirect - Live Migration Users may experience performance issues during live migration of cluster nodes resulting in timeouts triggering failures across the stack. Network traffic is not flowing in through RDMA among cluster nodes resulting in a fallback to TCP/IP and reduced performance of up to 5x Live Migration times causing timeout-related failures.

From Server 2022 up to this newest 26063 build, they all have the same problem, as described here: https://techcommunity.microsoft.com/t5/windows-server-insiders/server-vnext-26040-and-server-2022-deduplication-data-corruption/m-p/4047321 I am out of energy for today and give up for today. It seems to be impossible to get Microsoft to care for actual OS bugs instead of marketing.Joachim_OtahalOct 30, 2025Iron Contributor4.5KViews1like21CommentsProblems to join Debian/Ubuntu machines to a domain

A few days ago, my PC automatically updated from version 24H2 to 25H2, and ever since then, I've been experiencing persistent issues that I haven't been able to resolve. Unfortunately, the option to roll back to the previous version seems to be unavailable, which has made troubleshooting even more difficult. I've tried just about everything I could think of—tweaking settings, running diagnostics, checking for compatibility problems, and even reaching out to support forums—but nothing has worked so far. It's been incredibly frustrating, and I'm still stuck with the same problem.Austin1Oct 30, 2025Copper Contributor154Views0likes2CommentsMicrosoft Store Error – “Sorry about that! Something went wrong, but we are making it right.”
Hello Insider Community, I’m currently experiencing a persistent issue with the Microsoft Store on my Windows device. Every time I try to open the Store or update apps, I receive the following error message: > “Sorry about that! Something went wrong, but we are making it right.” This has been happening consistently, and clicking “Refresh” does not resolve the issue. I’ve already tried the following troubleshooting steps: - Resetting the Store cache using `wsreset.exe` - Repairing and resetting the Store via Settings - Re-registering the Store using PowerShell - Verifying time, region, and account settings - Running SFC and DISM scans - Restarting the Microsoft Store Install Service Despite these efforts, the error persists. I am signed in with a Microsoft account, and my internet connection is stable. I’m not using a VPN or proxy. I’m currently on [WINDOWS 11 HOME SL, INSIDER BUILD DEV CHANNEL] Any guidance, known workarounds, or confirmation of this being a known Insider build issueshasukeyoichiiOct 30, 2025Copper Contributor57Views0likes2Comments
