Relaying and highlighting a blog from Borncity for those who use Windows 7 or Windows 8.1 with either Google Chrome or Brave Browsers.
Apparently popups appear warning users of support for the browser(s) ending and to move to windows 10 for continued support.
To suppress the warning, navigate to the following within regedit and add the following:
To suppress the Chrome warning:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Policies\Google\Chrome]
“SuppressUnsupportedOSWarning”=dword:00000001
To suppress the Brave warning:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Policies\BraveSoftware\Brave]
“SuppressUnsupportedOSWarning”=dword:00000001
Many thanks to Guenni and those who reported the observation
