All current Windows products require activation with Microsoft to confirm their validity and prevent software piracy. This can be a simple and easy process for computers connected lớn the mạng internet or in an office environment with access lớn a Key Management hệ thống (KMS), which can handle the activation process in the background. KMS periodically reactivates Windows on machines to ensure their licenses remain legitimate.

Unfortunately, it’s a bit trickier to get Windows activated if you’re not fortunate enough lớn have internet access (such as on a system connected to lớn an internal network subnet that does not permit internet access for security reasons) or a working KMS server.

Must-read Windows coverage

In my case, I ran afoul of a rampant Windows activation prompt on several company-owned servers I administer because the KMS hệ thống went down và eventually the servers stopped using what they considered valid licenses. Worse, Microsoft limits the functionality of unactivated Windows machines, preventing you from performing tasks such as customizing the taskbar or applying patches.

Since these servers were due for some critical patches to be applied, I needed to move as fast as possible. I was able to quickly get Windows activated on these machines while also preparing lớn get a new KMS hệ thống stood up after the fact. I conducted these steps on several Windows 2012 machines, but they should also apply to lớn Windows 10, 11 and 2016.

You can use this process whether you have a KMS vps that’s “in the shop,” so to lớn speak, or you don’t have a KMS server at all. It relies on a điện thoại cảm ứng with texting capability, so make sure to have one handy.

I want to stress that this is a legitimate process sanctioned by Microsoft; it is not a “hack,” nor does it involve piracy.

First you will likely need khổng lồ right-click the Start menu, choose System, click Activate Windows or Change The sản phẩm Key Or nâng cấp Your Version Of Windows, then click Change product Key & apply the sản phẩm key.

In my case, Windows wouldn’t accept the key I knew to be valid, so I opened a command prompt và ran the slmgr (Software License Manager) command as follows:

slmgr /ipk (Windows sản phẩm key)

That worked, so next I used the Software License User Interface command khổng lồ run:

slui 0x4

This kicks off the offline activation process. You’ll be prompted to lớn select your country or region (Figure A).

Once you click Next, you’ll be provided a screen similar khổng lồ the one in Figure B.

Call the number shown & you will be walked through a menu by a voice assistant that will ask whether you consent for the gọi to be recorded and ask what sản phẩm you’re calling about. Answer “Windows” & then when asked if you have a điện thoại cảm ứng say “yes” and consent to the suggestion that the assistant text a liên kết to your phone, which you can use lớn complete the activation process. This is much faster và easier than using the mặc định phone-based interface, which is slow và tedious, not to mention prone lớn error.

The text will come in right away. As you can see in Figure C, I had to lớn repeat the call a few times over the course of my work as the link does expire, but if you’re fast enough, the same links will work for two or three activations so you can reduce the times you must initiate the phone call.

Click the link and then you’ll be taken to lớn a page similar to lớn the one in Figure D.

In my case, there were seven digits in the first block of the installation ID in the activation window, so I selected that as my answer.

I was then prompted lớn enter the nine sequences of numbers shown on my server in the next screen on my phone (Figure E). Please cảnh báo I had khổng lồ tap the empty field under “1” a few times before the option to plug in the digits came up; this caused me a bit of confusion và doubt about the functionality of the interface, but it worked fine once I knew the way to lớn proceed.

Once I put in the entire mix of sequences I clicked Submit.

I was then taken to lớn the screen shown in Figure F, which gave me eight sequences of numbers as shown. These numbers are based upon the numbers that had been displayed on my server screen under the Installation ID section. They are unique và based upon my Windows sản phẩm code, so they will activate only that server.

I switched back to my server và clicked Enter Confirmation ID và was taken lớn the screen shown in Figure G.

I then typed in the eight sequences of numbers on my điện thoại cảm ứng and clicked Activate Windows, which brought up the screen shown in Figure H.
