One of the biggest issues between a bit OS and a bit OS is addressable memory, and a bit OS can manage far more memory natively than a bit OS can. I concur with Mike. The best I was even able to manage was 3. A fresh install of win10 64 bit resolves the 4 GB memory addressing limitation. While there is a new limit for 64 bit but its much larger.

There is a well-known property of Windows. There are a number of technical reasons for this. First, any bit version of Windows should be showing usable memory of about 3. If your observations are correct, something else is going on. One possibility is that your 4 Gigabytes of memory is installed incorrectly. If you have more than two memory slots, and you are using two 2 Gigabyte memory cards, they should be installed in a pair of memory slots.

If you have your memory installed with 2 Gigabytes in one slot, and 2 Gigabytes in a non-matching slot, your computer may be able to run with just the first 2 Gigabytes; it is just possible that Windows 7 was able to recognize the other 2 Gigabytes when the later operating systems used stricter configuration checking and could not.

Get the documentation for your computer, and check how your memory is installed. Only 32 bit for the virtual environment. How do I get 64 bits? However, only 32 bit installations are shown to me as a possibility. I used Windows 10 as operating system 64Bit. Hyper V is not installed! Wie bekomme ich 64 Bit?
