Windows 10: 64- and 32-bit

    64- and 32-bit


    I have a 64-bit capable PC but to date I've only ever installed 32-bit versions of Windows. If I create a new bootable partition can I have a 64-bit W10 installation running there? (My guess is "yes" but I thought I'd check)

    Hello RTWFF,

    Yes, you sure could.

    Yes, but unless you have more than 4GB of memory, stay with 32 bit.

    Actually, more than 3GB of memory. Most computers with 4GB can't use all 4GB in a 32 bit OS. you will only have 3.2GB or so available due to reserved memory.

    Using a 64 bit OS with 4GB allows you to use all 4GB.

    I plan on increasing the memory to 8GB or more

    Hi there

    Providing you have the VT enabled in the BIOS (most machines do these days) you can try running a 64 Bit GUEST as a VM -- VMWARE CAN run 64 bit guests on 32 bit hosts. (Test the VM with 2 GB RAM - it will work - I've had W8 and W10 VM's on 2 GB RAM while testing).

    I've had a W7 Enterprise x-64 bit guest running on XP Host when I was testing W7 a few years ago. (Time flies - was it that long ago !!).

    A VM is an excellent way of testing a new OS and you also learn about Virtual Machines too. Then if you like the OS you can then decide to install it on your PHYSICAL machine.

    Cheers

    32 bit will almost always address all the 4gb RAM when hardware is taken into account.

    You can check how much RAM is apportioned to hardware by typing Resource Monitor in Start Search box and clicking on the Memory tab.

    In any case, you'll get better performance from 32 bit with 4gb RAM and under.
