I wouldn't recommend using an old O/S for heavy web browsing, but the banner can be annoying if streaming video.
It can be permanently disabled with the following registry settings.
Code: Select all
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge]
"SuppressUnsupportedOSWarning"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]
"SuppressUnsupportedOSWarning"=dword:00000001
