I have released ExplorerPatcher version 22621.608.51.1 which fixes the network and battery flyouts not working on 22H2 builds. Sorry for the delay, I have been quite busy lately with some other work. I checked it out at a basic level on both 22000.1042 and 22621.608 and it seemed to work fine. It's been promoted to release status already, as the changes are punctual and rather minor, no prior functionality should be affected.
22621.608.51.1
* Fixed a bug that could prevent the Windows 10 network or battery flyouts from showing on OS build 22000.
* Fixed the Windows 10 network and battery flyouts on OS build 22621.
* Weather: Fixed a bug that displayed the widget contents with incorrect left padding.
Please note: when you update to this version, the update notification will show 22622.608.51.1 as being available instead of 22621.608.51.1. This is expected, as I decided to have ExplorerPatcher use 22621 as the major build number as that is the OS version it is tested against, so it made much more sense to keep the two in sync. Unfortunately, I cannot retroactively update code that you already have running on your machine, so a bit of trickery was necessary to get you updated to a newer version with an older build number (the updater, by default, doesn't "upgrade" you to versions having a build number that's lower than what you have installed). The single side effect is that, when you upgrade, you see the wrong build number for the new version. After upgrading, future versions will be displayed as 22621..., until and if I ever decide to bump it up to 22622 again. This is just a cosmetic nuissance - there is no new 22622.608.51.1 version; 22621.608.51.1 is the latest version which contains the latest fixes and enhancements for both OS builds 22621.608 and 22000.1042.
