Activate Windows 11 All Editions for FREE using KMS Client Key with a Batch Script – Windows 11 has become one of the most advanced and user-friendly operating systems released by Microsoft. However, activating it legally can sometimes be challenging for users who don’t have a product key. While Microsoft provides KMS (Key Management Service) activation methods for enterprise environments, many users can legally use KMS client keys for temporary activation purposes.
In this comprehensive guide, we’ll explore how to activate any edition of Windows 11 for free using a KMS client key and a batch script — all without needing any third-party software or cracks. This method is 100% script-based and transparent, giving you peace of mind.
Disclaimer: This guide is intended for educational purposes only. KMS activation is intended for volume license users. Personal or unauthorized use of KMS servers may violate Microsoft’s EULA. Use this method responsibly and only if you’re allowed to under your licensing agreement.
What is KMS Activation?
KMS (Key Management Service) is a legitimate technology by Microsoft that allows organizations to activate systems within their own network. Instead of requiring each machine to connect to Microsoft’s activation servers, KMS allows a central server to handle activation for all machines connected to it.
Windows editions that support KMS activation include:
- Windows 11 Home
- Windows 11 Home Single Language
- Windows 11 Pro
- Windows 11 Pro Education
- Windows 11 Pro for Workstations
- Windows 11 Education
- Windows 11 Enterprise
Each of these editions has its own KMS Client Setup Key, publicly available on Microsoft’s official documentation.

Let the script run. You’ll see activation progress and the final status (The machine is permanently activated or activated until xx date).
Troubleshooting Common Issues
Error: “0xC004F074 – The software licensing service reported that the computer could not be activated…”
Solution: This usually means the KMS server is unreachable. Try changing the server to one of the below:
cmdCopyEditslmgr /skms kms.digiboy.ir
slmgr /skms kms.msguides.com
slmgr /skms zh.us.to
slmgr /skms kms8.msguides.com
Error: “Access Denied”
Solution: You must run the script as an administrator.
Activation doesn’t persist after restart
Solution: KMS client keys offer 180-day activation. The system tries to auto-renew every 7 days. If activation is lost, just re-run the script.
How to Change Your Windows Edition
If you’re on Windows 11 Home and want to upgrade to Pro before activation, use this command:
cmdCopyEditchangepk.exe /ProductKey W269N-WFGWX-YVC9B-4J6C9-T83GX
Then reboot and run the batch script again.
How to Remove KMS Key or Reset Activation
To uninstall the KMS key:
cmdCopyEditslmgr /upk
To remove the KMS server address:
cmdCopyEditslmgr /ckms
To clear all activation information:
cmdCopyEditslmgr /rearm
Then restart the system.
Confirming Activation Status
To check if your activation was successful:
- Open Command Prompt as Admin.
- Type: cmdCopyEdit
slmgr /xpr
You’ll see a message like:
“This machine is permanently activated”
or
“Windows will expire after xx days”
Pros and Cons of Using KMS Activation

Is This Method Legal?
Using KMS activation with Microsoft-provided KMS client keys is legal only in enterprise environments or for educational/testing purposes. Activating Windows this way for personal long-term use may violate Microsoft’s End User License Agreement.
If you’re using Windows regularly for personal or business use, consider purchasing a retail key or a legitimate OEM license.
Re-activation Strategy
Since KMS activations are valid for 180 days, you can:
- Re-run the batch file every 6 months.
- Schedule it using Windows Task Scheduler for automation.
- Set a reminder to check activation using
slmgr /xpr.

Q2: Will Windows updates work?
Yes, this method doesn’t block updates or access to Microsoft services.
Q3: Can I activate Microsoft Office using KMS too?
Yes, Microsoft Office (Volume Editions like Pro Plus) can also be activated using KMS. A similar batch script is used with Office KMS client keys.
Q4: Is it safe for long-term use?
