A Retail license registered on my MS account now belongs to a device that does not exist anymore. Let’s say that my sample machine was a real, physical machine, and that it died. That’s it, the digital license is now ready to be transferred. One last check: I will go to and check that the new machine, and its digital license have been added to my MS account: Whichever method you choose, after switching to a Microsoft account or adding an MS account to a local account, the activation status changes to Activated with a digital license linked to your Microsoft account:

However, if you are like me and want to continue using a local account, do not click that link! See this earlier story, scroll down to title Why not best of both?, and see how to add a Microsoft account to Windows 10 without switching a local account to a Microsoft account: Microsoft Account vs. If a Microsoft account is what you want to use, click Add an account and follow the on-screen instructions to sign in. If I now clicked the Add an account under Add a Microsoft Account link, my local account would be switched to a Microsoft Account, and this license would be registered for that MS account. At this point, activation status is shown as Activated with a digital license:Ĭlick screenshots to open enlarged in a new tab.

When transferring the license, it is important that you know the device name for the license you wish to transfer.Īfter the restart required by renaming the machine, I activated this VM using one of my MAK keys for the Windows 10 Pro edition. I renamed the machine to VM-W10PRO07, it being the seventh W10 Pro VM I have activated. The first thing to do is to change the device name to something that will later clearly tell me which machine this is.

As an example, I have just performed a clean install of W10 Pro on a Hyper-V virtual machine, although exactly the same applies to physical devices, too. This is the only way to be sure that license can be reused for reactivation after replacing hardware or transferring that license to a new device. Taking care of Digital LicensesĮven if you use only a local account to sign in to Windows 10, it is important to create a Microsoft account, if you do not have one already. Windows 10 will be automatically activated, based on the HWID and the existing digital license. You can replace your HDD containing a licensed 64-bit Windows 10 Pro version 1809 in English, and install a 32-bit Windows 10 Pro version 1909 in Swedish on a new HDD. That said, a digital license is edition specific, but not language, version or bit architecture specific. This means that a user is free to replace an HDD or SSD without losing his or her Windows 10 license. Notice that disk drives are not included in the HWID.

See the full list: Specifying Hardware IDs for a Computer. Microsoft has 15 different hardware IDs to be used in various scenarios, the one that determines if a digital license on a device is valid is hardware ID 3. However, its hardware ID (HWID) must remain the same (no major hardware changes). When Windows 10 is activated for the first time, that device gets a valid digital license for the activated edition, for the lifetime of that device. If it shows that your license is from OEM channel, you cannot transfer the license: Software License Manager opens a prompt telling about your license. To check if you have an OEM, non-transferrable license, enter the following command in an elevated PowerShell or Command Prompt: slmgr /dli One somewhat grey area is Microsoft’s tech support: on various tech sites and forums you can read about users claiming that talking to the activation helpline succeeded, and an OEM license reactivated even after both motherboard and CPU were swapped out and automatic activation failed. OEM licenses can’t be transferred to new devices, and they cannot be used to reactivate Windows 10 when major hardware changes such as replacing motherboards occur.

Multiple Activation Keys (MAK) are also shown as Retail in the Windows Software License Manager (slmgr.vbs). All single use Visual Studio subscription keys are also Retail keys. One exception: so-called System Builder versions which are also OEM licenses. If Windows 10 was purchased from Microsoft or some licensed retailer, it is a Retail license. Here’s a good rule of thumb: If a Windows 10 device comes with Windows preinstalled, it is a so-called OEM (Original Equipment Manufacturer) license. Taking care of your digital licenses is equally important whether you have just one device, or a complex home network with multiple devices. Many of you geeks have a Visual Studio subscription (formerly known as MSDN), with lots of product keys to use.
