I remember buying a PC with Windows 10 home thinking it was Windows Pro. Remember Windows is registered with your computer's bios chip so if you get a "pirated" version, if you ever have to do a clean install you will have added steps to re-install, real PITA.
I only bought a new laptop as the price was too hard to give up....$850 Canadian for an Lenovo E16 Gen 2 with 16gb ram....1 TB SSD and Windows 11 Pro. More importantly Windows 10 is coming to end of life, Had my windows 10 laptop for 7 years and never a problem but concerned for security updates etc. But the price for a new one was too good to give up. So much for the environment!!!
That being said, if you keep your laptop 7 years think of it as only spending $15 for the upgrade....I also assume when Windows 12 comes you will qualify for a free upgrade. If you're running an older laptop with Windows 11 home maybe wait.....windows 12 may not run on your current configuration. The laws need to change....I see no reason why a computer meets my needs has to be thrown out because software companies no longer provide security updates.
