Salesforce system requirements for LEX say I should have "the latest" version of Edge installed. (https://help.salesforce.com/articleView?id=getstart_browsers_sfx.htm&type=5) Edge is part of Windows 10, and cannot be upgraded apart from Windows 10. Though there are more recent versions of Edge, because my OS is up to date (according to Windows Update), I cannot get any more recent versions of Edge on my machine unless/until Microsoft releases an update to my OS.
So do I meet the system requirements for LEX right now, or does my OS have to change in order to meet the LEX browser requirements? (BTW, because it is part of the OS, you can't uninstall Edge in order to just install "the latest").
Feel free to try these steps to see if it helps you:
Step 1: Search for ‘Settings’ from the taskbar, and launch it.
Step 2: Click on Update and Security from the Settings window.
Step 3: From the left side menu, click on Windows Update.
Step 4: You can manually check for updates from here. Windows may also list available but not installed updates here. Click on Install now to install and update Windows 10 as shown in the image below.
As you stated, you can't update it independently but this should allow you to check windows manually to see if their is an update that you can apply to your machine. You can manually trigger the process to install a particular update from this utility if their is an update to apply.
