Like most of you who bought computers with Windows 8 installed, I couldn't wait for the upgrade to Windows 10. With all the hate among people and ethnic groups in the world today, I'm sure the one issue that can unite us all is our collective hatred of Windows 8. I have three computers. One laptop seamlessly migrated to Windows 10. One laptop has been nothing but a headache, and is still not migrated. And my desktop -- after numerous attempts at the upgrade -- is now deemed to be "not upgradeable." (I'm so sorry I bought a Gateway product. Their support has been terrible.) I'm on a first name basis with MS technicians in Manilla, and that's not a good thing.
I'd like to know what everyone else's upgrade experience has been. It would help if you'd mention what computer you have. BTW, I did learn from all this that your RAM size does matter with the upgrade.
