The cynic in me asks if this isn’t a back door approach for MS to degrade the performance of legacy OS’s.
Nah, highly unlikely it's intentional.
HOWEVER, it is certainly a reminder that running older releases of Windows is even more risky than running recent releases of Windows.
Microsoft REALLY, REALLY, REALLY wants you to migrate to Windows 10.
REALLY.
I agree. I do not do updates, at all. I’ve turned off remote desktop.
