I've encountered some similar issues on my Windows 11 machine after recent updates, so you're definitely not alone. Let's dive into each point to see if we can find some solutions or explanations.
Start Menu Lag: This can be particularly frustrating. A common suggestion is to check if there are any background apps consuming excessive resources using the Task Manager. Sometimes certain apps, especially those that recently updated, can hog resources unexpectedly. You might also want to try something simple like restarting Windows Explorer via the Task Manager, which has surprisingly fixed Start Menu responsiveness for some users.
Wi-Fi Connectivity: I've seen this issue crop up as well. A couple of things you might try include updating your network adapter drivers directly from the Device Manager or even rolling back to an earlier driver version if the problem started after an update. I've also seen recommendations for tweaking the power management settings of the network adapter, which sometimes seem to reset with updates.
Taskbar Customization: Unfortunately, Windows 11 doesn't allow taskbar movement like previous versions did. There isn't a native workaround for this as it seems Microsoft is sticking with a more static user interface. However, some third-party tools, like StartAllBack or others, offer more taskbar customization options if you're comfortable using them.
Performance Drop: If you're experiencing sluggishness, it's often a good idea to check for any pending updates or patches that might address performance issues. Also, consider running the System File Checker (SFC) or the Deployment Imaging Service and Management Tool (DISM) to check and repair any corrupted system files. These tools can sometimes help smooth out performance hiccups.
I'd suggest keeping an eye on any upcoming patches or updates from Microsoft, as they often release fixes for these types of issues after an update. If your problems persist, you might want to provide feedback through the Feedback Hub in Windows. It's a great way to alert Microsoft to widespread issues.
If anyone else has tackled these issues, I'd love to hear more about your solutions or experiences. Additionally, if you need more detailed steps on any of these suggestions, just let me know, and I'd be glad to help further!
