Windows Activator: 3 Ways to Use Your OS for Free

An unactivated operating system causes a lot of trouble: it restricts access to certain functions, restarts the computer at the wrong time, displays watermarks, and so on. So users who do not want to buy a license are looking for the simplest ways to activate the OS for free.

The most popular solutions are using Win activator programs and Windows license keys. Let’s look at each way and determine the pros and cons.

KMS Activators

A KMS activator is a clear winner among modern effective license bypass tools. The best programs in this line are KMSpico and KMSAuto.

How it works

KMSAuto and KMSpico place a license activation key into the OS and create a local server on the computer that replaces the official activation server. 

Many users use KMS services as an alternative to Win 11 keygen and Win 10 keygen since the KMS model is more efficient for the latest OS releases.

How to use

  1. Download the program archive from a site you can trust.
  2. Before unpacking, disable your antivirus and Windows Defender.
  3. Extract the contents to a folder on your desktop, and run the .exe file as an administrator.
  4. In the dialog box, select OS activation and click the button.
  5. Wait until the status bar shows that the activation was successful.
  6. Restart your computer.


  • Simple and effective Win 11 activator and Win 10 activator that any user can understand.
  • Works well for activating both early versions of the OS and the latest releases.
  • Independently activate the OS every 180 days.


  • May be infected with a trojan virus since many scammers modify the code and put infected assemblies on the site.
  • Activation sometimes crashes due to the operation of the antivirus, so the program has to be restarted.

Windows Key Activator

There are several ways to find keys to activate your OS, the main two are to look for keys on websites and enter them manually or use the KeyGen program. Let’s talk about everything in order.

License keys on the websites

There are a lot of sites on the Internet that host lists of license keys. Some of them may work. Each version and edition of the OS has its own keys, so look for “Windows 11 key,” “Windows 10 key,” etc. in the names. 

The Windows 8 key and the Windows 7 key are also updated periodically, so you can find the ones that work.

How to use

  1. Copy the license key on one of the sites.
  2. Click the Start button, select Settings > System > Activation > Update product key > Change product key.
  3. Enter the license key, and click the “Activate” button.
  4. If successful, restart your computer and use the active OS.
  5. If the key does not fit, try another one.


  • It’s a secure activation method, as you do not need to install unfamiliar programs that can affect the system.


  • Finding a working key can take a long time.
  • Windows activation may fail when installing updates, switching to a new version of the OS, or replacing hardware for your PC with 10 OS (for example, a motherboard or RAM).

Windows Keygen Activator

If you take the key from the Internet, you may encounter problems again. This happens because Microsoft keeps track of keys. And if your key is exposed, your system may be deactivated and you will have to look for a new key. 

In order not to waste time on this, many users use a key generation program. And it’s a simple decision to use Win 8 keygen or Win 7 keygen to activate your OS.

How it works

Keygen selects and generates license keys for Windows. Keys from the generator also sometimes stop working, but the program itself can restore activation. Keygen creates a task that it executes on schedule. 

How to use

You will have to do a bit of work to find a Windows 11 keygen and Windows 10 keygen. This solution was popular for older versions; therefore, Win 8 activator and Win 7 activator assemblies are most often placed on the site.

Installation is very simple:

  1. Download keygen activator files.
  2. Disable your antivirus.
  3. Unzip the archive and run the app as an administrator.
  4. Wait for the program to finish activation.


Key Generator is comfortable to use, reliable, and works by itself.


  • Some key generation programs affect the operation of the OS, which can lead to system failures.
  • Windows 8 keygen and Windows 7 keygen work better because previous OS versions are simpler to activate.

Windows Loader

The last solution in our list is the Windows Loader program. The utility was especially popular at the time of Windows 7 and Vista, but with the release of Windows 10, the KMS program became more popular, and Loader was no longer updated. However, if you have an old OS version, a Windows 8 loader or Windows 7 loader would be perfect for you.

How it works

The program activates the license that is embedded in the BIOS SLIC area of your computer. That is, if your computer was released along with the OS, then this program will suit you. If you’re using a PC that doesn’t have an OEM license, Windows Loader won’t be able to do anything.

How to use

  1. Download a Windows Loader program, and disable the antivirus.
  2. Run the application as an administrator.
  3. Click on the “Install” button and wait for the process to complete.
  4. Restart your computer.


  • There are a minimum number of settings inside the utility.
  • It has an intuitive interface.


  • There may be activation issues after installing OS updates, as developers regularly release new ones for Windows authentication.
  • The network does not have the Windows 10 Loader and Windows 11 Loader utility, so you need to use other activation methods to upgrade to new versions of the OS.

Final Thoughts

There are many ways to activate Windows for free. It’s hard to say which one is better, as they all work. We hope this summary can help you to choose the most suitable one.
