Windows 10 will likely be the last popular desktop and laptop OS for Microsoft. I have 4 to 6 year old desktop and laptop replacements for myself and my mother to migrate to later this year which are business cheap castoffs. They fully support windows 11 if needed.
My employer ended the laptop and office workstation program and we do ALL work on Samsung Phones and have access to Samsung tablets with keyboards for any 'desktop work'. Even our products which consist of 50% of the world's ATM market and our sister company which makes 30% of the world's POS, kiosk and self checkout systems will likely NEVER be going windows 11.
The winds of change are blowing all while Microsoft stands idly with fingers in its ears, eyes closed and holding their breath until Blue in the face.
Windows is likely already dead, the replacement just hasn't fully supplanted it yet.
