For sure, even in new 'Pentium' & 'Celeron' based processors for low powered computing, certain upgrades exist which support elements of new basic language used by Windows 10 / 11 & other platforms to aid performance. Let's face it, these budget CPU's need it, as they struggle with simple computing & multi- tasking.
HOWEVER, the i7-6700 Quad Core/8 thread processor in a general Windows environment is a beast even today, fast enough & then some... At its release this was a serious gaming CPU, & its not that old & still faster & smarter than entry level gaming CPU's on todays market.
There is absolutely NO CHANCE Microsoft found creditable negative results in running Windows 11 alongside this processor.
And sorry Joe13 B-) 2.0 2.0") , your defence regarding security platforms sounds like a highly logical reason to support MS's decision, however, aside from nanostructure changes & gen- to- gen performance boosts, the list of approved CPU's issued by Microsoft do not support your theory and are inconsistent. Plus Windows security can be handled within BIOS & in other ways.
So, I put it to a qualified Microsoft technician (not sales, admin, customer services or similar) to assist in this thread & please, share the test results for the i7 6700 & demonstrate the exact area where performance was unstable?
In this retail dominated industry there are many building their own PC's & systems, who should be able to keep up with OS advances & tune- up around them.
I left OSX for Windows, 10 years ago due to Apple's clear strategies of force- voiding $3,000+ personal computers after 3-5 years via software bullying.
I would hope for better responsibility from the worlds preferred operating System, so please issue the proof; before many have to part with serious money on new CPU's & motherboards, or an entire new PC.
