here is the windows registry values you need to change:
"
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Policies\BraveSoftware\Brave]
“SuppressUnsupportedOSWarning”=dword:00000001
"
if it doesn’t work at first, type cmd into the search box, right click and select “run as administer”
then in the command prompt type “regedit32” , from there you can navigate the tree structure to find the same entries. you will need to make a new DWORD entry.
it may be intimidating but i believe you can do it!
