> Win 10 and 11
Windows is just Windows at this point. You are still using the Windows 8 license that your purchased. The version numbers are nothing more than a measurement of how brazen Microsoft is getting.
Show me where I can get a legal copy of Windows that is free to install on a pristine machine and I'll concede that it is free.
Microsoft have simply added a subscription fee to Windows, where you are the subscription fee.
Have been? You didn't have to have an already licensed Windows installation to upgrade? You _exchanged_ your older license for the newer one for free; you didn't get one extra for free.
When you purchase a complete, new computer, the windows license is included in price (OEM). If you build your computer from parts or when you spin a new VM, you have to get a new license. Windows 10/11 Home (OEM) is about 120 EUR + VAT, Pro (OEM) about 160 EUR + VAT. That's quite a far cry from free.
