Did Mulder really say that?
Over the years, as a computer tech, working in both a shop and in my own business, I've worked on hundreds of PC's made by local shops and almost NONE of those PC's had a licensed version of Windows installed on it.
That goes back many years to the very beginning of "Windows".
Most users today, as in the past, have no idea if their version of Windows is licensed or not and couldn't care less.
As for upgrading XP to Windows 10, many of the older XP machines couldn't run Windows 10 anyway. There are many XP PC's still running on just 256 or maybe 512 megs of Ram. Not running very well, , , , but 'running'.
I've tried W-10 on a few really old PC's, that run XP, here in my own shop and it was a NO-GO!
The installer goes just so far and then stops with a BSOD.
Looking ahead..... Y'all have a great Memorial Day!
PS: In early 2014, the VA Hospital was still running Windows XP-Pro on all their terminals (PC's)
They finally upgraded to Windows 7, which has already had its EOS date posted by MS.
Could that be called, "too little, too late".???
