In the Microsoft system requirements, it states you need 2 GB (64-bit systems) of ram for Windows 10. Is this enough? From our research and testing, it seems that 2GB will just barely function. Add some background programs and start to open other programs and the system will start to struggle. Forget about opening a modern web browser with a few tabs. This will just chew up any reserve memory you might have had. We recommend 4GB at a minimum if you plan on upgrading on or after this July 29th (P.S. not everyone will get windows 10 July 29th even if you reserved a copy). Please let us know if you need help determining if you have enough ram for Windows 10 or checking to see if you meet the other system requirements.
