Windows 10: Why did windows allow me to activate 2 computers using 1 license?

So, recently I've built a new pc, and I wanted to transfer my digital windows 10 Pro license tied to my account, from the old pc to the new. I've clicked on Troubleshoot button in Activation settings on my new pc, clicked on "Recently upgraded components", and it just activated my new pc. All of that is totally right and fine, however my old pc is still activated. Do I need to deactivate it manually? Or is it a totally new license I've received somehow?

Transfer Windows 10 license to another computer.

Hi,



Thank you for writing to Microsoft Community Forums.



Please note that one license key is valid only for one hardware. However you can try the steps mentioned below to check if that helps. Make sure that you have the 25-alpha numeric product key (Retail version). Here are some steps that you can follow:



Step 1: Uninstall the key from your Mac (Bootcamp). To uninstall the license key, follow the steps mentioned bellow:

1. Open command prompt (search CMD on start menu) and run it as administrator.
   
2. Then type: slmgr /upk
3. The following command will uninstall the product key from your Bootcamp partition.
   

Step 2: Install the product key on new Computer.

1. Open Run (Windows Key + R) and then type: SLUI 3
2. You will be prompted to enter the product key.
3. Please type the product key and try to activate it.

Step 3: If step 2 does not work, then you will need to install the product key manually and perform phone activation.

1. Open Command prompt once again and run it administrator.
2. Then type: slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
   
   Note: replace XXXXX with the product key.
3. Once you receive a confirmation prompt that the product key has been installed.
   
4. Close the Command prompt Window.
5. Now open Run (Windows Key + R) and type SLUI 4.
6. Then choose your country and click on Next and follow the on screen instructions.

Hope this helps.

Glossary

OEM – Original Equipment manufacturer license, this license is generally supplied with your computer when you buy it, as the title says it’s a license that the manufacturer used to activate Windows on your original equipment,
this license loses its value and will no longer work when you change hardware. More information can be found here:
Licensing FAQ

Troubleshooting: You changed hardware and can no longer activate Windows

When you’re using a system build by someone else like HP, DELL and so on and you replace vital system parts the supplied OEM license will expire and become invalid. There is nothing you can do about this and there is no way
to solve this.

To make sure you’re using an OEM license check the sticker located on your system, it should include the tekst OEM or C(O)A.. Microsoft offers no support and it’s best to contact your systems manufacturer.

1. Troubleshooting: 0xC004F074. Software Licensing Service reported that the computer cannot be activated.

This is a common error in Windows 8 and can be solved quite easily in most cases, the steps you have to take to solve the issues are listed below:

1. Open elevated command prompt>
   1. Press the Windows + W key on your keyboard and type
      cmd, then right-click Command prompt and choose
      Run as Administrator
   2. Press the Windows + X key on your keyboard and choose Command Prompt (Admin)
2. Type slmgr.vbs –ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX (Replace the X’es with your 25 digit product key)
3. Hit Enter
4. Type slmgr.vbs –ato
5. Hit Enter

If this did not fix your problem then read “General Troubleshooting: Windows can’t activate the license.”

2. Troubleshooting: 0x8007232B & 0x8007007B. KMS Host could not be located in domain name system


This error is not common under end-users (consumers) since it’s a KMS error which should only appear on Volume Licensing.

Key management services (KMS) host could not be located in domain name system (DNS), please have your system adminstrator verify that a KMS is published correctly in DNS.

The steps for solving this problem are the same as the steps given for the error 0xC004F074 please read the troubleshooting part for that error. If that did not solve your problem then this link might help you further. Resolve Windows activation error codes

3. Troubleshooting: 0xD0000010 & 0xc004c4aa. Unable to find a detailed error description.

The cause for this problem is a bit vague, its argued that removing any external hard disk, mobile phones and other USB devices from your system solves this issue. Try to remove any of these hardware devices and then reboot
Windows, it should show up as activated. If this indeed fixed your problem then update your chipset driver, this should solve the problem in most cases permanently.

If this did not fix your problem then read “General Troubleshooting: Windows can’t activate the license.”

4. Troubleshooting: 0x80072EE2. ERROR_INTERNET_TIMEOUT

The problem for this can be caused by Windows Update, run the automatic tool released by Microsoft and let it scan for any problems then solve them all using the program: Wenn nur eine Umarmung genügt .

If this does not work then disable all your firewalls and protection software and try again, be sure to re-enable them all again after successfully activating.

If this did not fix your problem then read “General Troubleshooting: Windows can’t activate the license.”

0xc004c008, 0x8007000D.


The fix for this issue is described in "
General Troubleshooting: Windows can’t activate the license. “ part of this Wiki. Please read that part.

6. Troubleshooting: 0xc0000022 ACCESS DENIED

There are a couple of reasons this error could appear, the first one is that you’re not signed in as Administrator and Windows can’t get access to the activation service.

The second one is corrupted system files, which can be fixed by running the SFC command from an elevated command prompt:”

1. Open elevated command prompt>
   1. Press the Windows + W key on your keyboard and type
      cmd, then right-click Command prompt and choose
      Run as Administrator
   2. Press the Windows + X key on your keyboard and choose Command Prompt (Admin)
2. Type SFC /scannow
3. Hit Enter
4. When the scan has finished, try to activate again.

If this did not fix your problem then read “General Troubleshooting: Windows can’t activate the license.”

When this does not work, then try to reset your system, if even that fails a complete refresh is the only way to go at this moment (23nd of April 2014).

programs and use a restore point, system refresh or reset to solve this issue.
