I’ve seen this question asked alot around the net with not many good answers and alot of guesses based on past Windows editions. Here’s the answer straight from Microsoft. I have the direct link to Microsoft’s website below, but incase it doesn’t work and to make things easier, here’s the breakdown for each edition of Windows and the difference between the 32bit and the 64 bit. The maximum RAM for Windows 7 starter edition is 2GB of RAM, regardless if it’s 32 bit or 64 bit edtion. All other editions have a maximum of 4GB of RAM memory unless you get the 64 bit edition, then you will see in the chart below how you can get up to a maximum of a whopping 192GB of RAM memory with the editions from the Professional edition and above.
