Not that impressed overall with 25H2. I have noticed rather strange performance degrades when running laptop on battery. Just feels laggy and I don't like the new Start menu at all. A step back in my opinion and the lack of being able to resize or customize it is frustrating. This is 2026 after all, and I just feel Windows 11 has become a take it as it is or move on to another OS. Luckily, I don't use Windows that much anymore. The stability has worsened so much I had to give up on Windows as a daily OS.
Microsoft's optional Windows 11 update KB5077241 (24H2/25H2) adds a built-in internet speed test, native Sysmon support, and fixes aimed at improving wake from sleep and overall responsiveness.
