Sep 20, 2015 Edition: Windows 10 pro Activation: Windows is not activated Activate Windows This product key doesn't work. You might need to get in touch with the store or company you bought windows from, or you can buy a new key from Microsoft It has the option to enter a new product key and this info below Your Product Key Info. Resetting and Activation with Windows 10. Also, OP does not make it clear if he reverts to official release, if he upgraded from a valid 7/8 licence (or holds a valid 10 licence) - if so, leaving the Insider program may cause it to become deactivated.
Windows activation is designed to be as foolproof as possible, so Microsoft’s graphical tools keep it simple. If you want to do something more advanced like remove a product key, force an online activation, or extend the activation timer, you’ll need Slmgr.vbs.
This command line tool is included with Windows, and provides options unavailable in the standard activation interface provided on the Update & Security > Activation screen in the Settings app.
RELATED:How Does Windows Activation Work?
To use this tool, you’ll want to launch a Command Prompt with Administrator access. To do so on Windows 8 or 10, either right-click the Start button or press Windows+X. Click the “Command Prompt (Admin)” option in the menu that appears. On Windows 7, search the Start menu for “Command Prompt,” right-click it, and select “Run as Administrator.”
Note: If you see PowerShell instead of Command Prompt on the Power Users menu, that’s a switch that came about with the Creators Update for Windows 10. It’s very easy to switch back to showing the Command Prompt on the Power Users menu if you want, or you can give PowerShell a try. You can do pretty much everything in PowerShell that you can do in Command Prompt, plus a lot of other useful things.
To display very basic license and activation information about the current system, run the following command. This command tells you the edition of Windows, part of the product key so you can identify it, and whether the system is activated.
To display more detailed license information–including the activation ID, installation ID, and other details–run the following command:
To display the expiration date of the current license, run the following command. This is only useful for Windows system activated from an organization’s KMS server, as retail licenses and multiple activation keys result in a perpetual license that won’t expire. If you haven’t provided a product key at all, it’ll give you an error message.
You can remove the product key from your current Windows system with Slmgr. After you run the below command and restart your computer, the Windows system won’t have a product key and will be in an unactivated, unlicensed state.
If you installed Windows from a retail license and would like to use that license on another computer, this allows you to remove the license. It could also be useful if you’re giving that computer away to someone else. However, most Windows licenses are tied to the computer they came with–unless you purchased a boxed copy.
To remove uninstall the current product key, run the following command and then restart your computer:
Windows also stores the product key in the registry, as it’s sometimes necessary for the key to be in the registry when setting up the computer. If you’ve uninstalled the product key, you should run the below command to ensure it’s removed from the registry as well. This will ensure people who use the computer in the future can’t grab the product key.
Running this command alone won’t uninstall your product key. It’ll remove it from the registry so programs can’t access it from there, but your Windows system will remain licensed unless you run the above command to actually uninstall the product key. This option is really designed to prevent the key from being stolen by malware, if malware running on the current system gains access to the registry.
You can use slmgr.vbs to enter a new product key. If the Windows system already has a product key, using the below command will silently replace the old product key with the one you provide.
Run the following command to replace the product key, replacing #####-#####-#####-#####-##### with the product key. The command will check the product key you enter to ensure it’s valid before using it. Microsoft advises you restart the computer after running this command.
You can also change your product key from the Activation screen in the Settings app, but this command lets you do it from the command line.

To force Windows to attempt an online activation, run the following command. If you’re using a retail edition of Windows, this will force Windows to attempt online activation with Microsoft’s servers. If the system is set up to use a KMS activation server, it will instead attempt activation with the KMS server on the local network. This command can be useful if Windows didn’t activate due to a connection or server problem and you want to force it to retry.
Slmgr also allows you to perform an offline activation. To get an installation ID for offline activation, run the following command:
You’ll now need to get a a confirmation ID you can use to activate the system over the phone. Call the Microsoft Product Activation Center, provide the installation ID you received above, and you’ll be given an activation ID if everything checks out. This allows you to activate Windows systems without Internet connections.
To enter the confirmation ID you’ve received for offline activation, run the following command. Replace “ACTIVATIONID” with the activation ID you’ve received.
Once you’re done, you can use the slmgr.vbs /dli or slmgr.vbs /dlv commands to confirm you’re activated.
This can generally be done from the Activation screen in the Settings app if your PC isn’t activated–you don’t have to use the command if you’d rather use the graphical interface.

Some Windows systems provide a limited time where you can use them as free trials before entering a product key. For example, Windows 7 offers a 30-day trial period before it begins complaining at you. To extend this trial period and reset it back to 30 days remaining, you can use the following command.As Microsoft’s documentation puts it, this command “resets the activation timers.”
This command can only be used several times, so you can’t indefinitely extend the trial. The number of time it can be used depends on the “rearm count,” which you can view using the slmgr.vbs /dlv command. It seems different on different versions of Windows–it was three times on Windows 7, and it seems to be five times on Windows Server 2008 R2.
This no longer seems to work on Windows 10, which is very lenient if you don’t provide it a product key anyway. This option still works on older versions of Windows and may continue to work on other editions of Windows, such as Windows Server, in the future.
Slmgr normally performs the actions you specify on the current computer. However, you can also remotely administer computers on your network if you have access to them. For example, the first command below applies to the current computer, while the second one will be run on a remote computer. You’ll just need the computer’s name, username, and password.
The Slmgr.vbs command has other options, which are useful for dealing with KMS activation and token-based activation. Consult Microsoft’s Slmgr.vbs documentation for more details.
