To be sincere, I am surprised that some people have not upgraded their Windows OS since many years ago, from Windows 7. First, Windows ends support for
Windows 7 since January 2020. Which means for the safety of device, Windows users needed to have upgraded to a version Windows are still releasing updates for. Also support for Windows 8 ended since
2016. Using such outdated OS makes your PC to be vulnerable to online attacks. Best to use the latest version of OS.
There has been several complains on this forum from Windows 7 users about error after updating to Electrum version 4.2.0. This is a release note about incompatibility of Windows 7 with Electrum 4.2.0.

Version 4.2.0 already unintentionally broke compatibility with
Win7 and there is no easy way to restore and maintain support.
Existing users can keep using version 4.1.5 for now, but should
consider upgrading or changing their OS.
Win8.1 still works but only Win10 is regularly tested.
- bump bundled Python version (win, mac, appimage) to 3.9.11,
(android) to 3.8.13 (1bb7ef92, #7721)
(note these include a fix to an openssl DOS-vector CVE-2022-0778)
- windows: bump pyinstaller to 4.10 and wine to 7.0 (#7721)
I posted this on this thread for more people to see this before deciding to updrage to Electrum version 4.2.0. If you are not using Windows 8.1, 10 or 10 Pro. Consider to upgrade your Windows OS, or use any other lastest desktop OS Electrum is
supportingNot that I am not recommenimg Windows, it is close source, a reason some bitcoin enthusiasts may not use it. But for just Windows users to know about this before updating to version 4.2.0
