    The thread title is invalid and gives false information. Windows 10 can and will be activated exactly the same way and following same rules, regardless if we are talking about virtual machines or real physical computers.

    I think I finally got what you meant.


    On a physical Machine, you can upgrade windows 7 to windows 10 on a physical machine and it will activate. You can wipe the hard drive and do a clean install of 10 on a physical machine skipping entering the keys and physical machine will activate.

    Instead of creating a new virtual machine, you wipe the virtual hard drive, then do a clean install of windows 10 and the virtual machine should activate. If you create a new virtual machine it considered a new computer even though it has all the same emulated hardware.

    FWIW and AFAIK it is not possible to do a clean install of W10 on a vm. Only an upgrade. I installed a retail 8.1 on a vm (VMware workstation v12 Pro) - upgrading was still not possible... meaning using the tasbar 'windows-upgrade' button. Windows stating that it will not upgrade (version is not suitable or something). The workaround is to use media creation tool and run the setup from there.
    With me it resulted in an activated W10 version. Obviously it is recommended to make snapshots of the 1st vm, as after a year 'upgrding ' isn't possible anymore.

    Yes, with one change in the scenario: do not wipe the VHD of the virtual machine containing the previous activated upgraded Windows 10. Instead boot that vm from Windows 10 install media and just select the install partition in the Windows installation disk setup dialog, as here in screenshot I have selected it (highlighted). Leave the system reserved and OEM (if exists) partitions intact:

    When installation is finished you can delete the Windows.old folder containing the previous upgraded Windows 10 installation.

    You will need to change somethings in the virtual player/box settings for it to work.

    Change the Virtual Machine Memory setting to 2048 ignore warning message if any

    Change to the correct operating system before upgrading in Virtual player setting

    Code:
    Change windows 7 64 bit to windows 10 64 bit  (If you have 64 bit system)
    Code:
    Change windows 8.1 64 bit to windows 10 64 bit  (If you have 64 bit system)
    Code:
    Change windows 7 32 bit to windows 10 32 bit  (If you have 32 bit system)
    Code:
    Change windows 8.1 32 bit to windows 10 32 bit  (If you have 32 bit system)
    This should allow you to upgrade to window 10 in a virtual machine.

    Thank you!
    Frankly, I wasn't aware of that.

    VMware Workstation has assigned 2GB RAM by itself - this I did not change manually.

    All the other items, assume you mean the below?

    BTW, I wonder what would be happening IF I were to change the working directory
    (D:\Virtual Machines\Windows 8 x64) to a new one, say:
    D:\Virtual Machines\Windows 10 x64

    would then the entire contents be moved from 8 x64 to 10 x64.
    I hesitate to just 'give it a try' fearing I would be messing up things.

    Anyway, thanks for your tips!

    Guest Operating system should be set at windows 10 x64 for your system before upgrading to windows 10 64 bit.


    I know when I switched the operating system info, the folder name was also change automatically but I was using the virtual box from a Linux host operating system. I assume vmware should change the folder name. If it doesn't in that same location, just change virtual machine name to windows 10 x64 and it should change the folder name.

    On the memory issue, you are fine and you can increase more since you have more memory installed. More you increase the memory, the less the host has to use when you are using the Virtual Machine. I would set it on your system at 8 gb. If you have problems running a game in the virtual machine you can always increase the memory to 16 gb later.

    Thanks. My experience with vmware is that the more memory you assign, the slower it gets. I have 32GB DDR4 RAM (2400) on X99 Asus and Intel i5820 and using two Samsung Pro 850 SSD's (512/1TB), so there is sufficient 'power' . I increased the 2GB to 8GB , assuming it would get faster, but instead it got rrreally terribly slow.

    Running Windows 10 x64 Pro as a host and vm is also 10 x64.

    The most likely reason for this is that VMWare is caching memory to disk. The fastest way is for the assigned memory to be only in RAM. To do this edit you .vmx file and add (or if already exist change) the following line.

    mainmem.useNamedFile = "FALSE"

    It will then not write the whole contents of your memory to the .vmem file in the VM directory. Unfortunately this only works in Workstation, not in Player which always creates the memory swap file.

    Hi there

    in addition to Kari's post :

    To get W10 activation as a VM you need to do the following

    1) Install W7 / W8 / W8.1 AS A VIRTUAL MACHINE , install updates and activate it.

    2) Now do an UPGRADE to W10 ON YOUR VIRTUAL MACHINE. This VM will be activated. DO NOT ENTER A PRODUCT KEY.

    3) Now a CLEAN install (as a VM) will work just fine - and it will be activated.

    I've performed this process using a Windows HOST as well as a LINUX HOST. Exactly the same considerations apply when using a VM as using a REAL machine.

    Can't see what the problem is.

    A VM needs a licence just the same as a REAL machine. I was using old TechNet serials for W7 / W8.1 to create the VM and then do the updates.

    Cheers

    Step 3 didn't work for me when I did those exact steps. Each time a new vm is created it is consider a new machine even though it has all the same hardware. When I did a clean install of 10. Windows 10 did not activate for me. I did try to reinstall windows 7 in a VM. It said key was blocked, that was because either I used it one to many time or windows 10 upgrade ate it don't know which. However, Noel said a phone call would fix the activation with windows 7 when I am ready to try it again and just explain what you did to Microsoft.
