Re: Given the cost of a Windows 10 Pro license...
agreed, but here's a better idea: just practice "safe surfing" and avoid the security problem altogether.
a) don't surf the web using a microsoft browser. If possible, don't use a microsoft OS, either.
b) don't open (aka 'double-click or in any way activate) anything downloaded from the internet. Open the program that views it and use 'file open' directly.
c) NEVER view e-mail as html. This includes WEB MAIL.
d) don't preview attachments inline - *EVER*
e) use NOSCRIPT or some other script-blocking tool on everything that isn't EXPLICITLY trusted.
and so on.
I still use XP for some things [like 3D printing]. that little box is just fine for that. It came with XP, and that's the way it is. Other former XP boxen became Linux boxen. One laptop got 7 on it. There is *NO* *NEED* *TO* *DOWNGRADE* *TO* *WIN-10-NIC* !!!
