     How to Fix Activation Error 0x8007007B on Windows 10 PC 

Hello Priya

You can refer to the following two cases:

1.If you' re having this problem on a personal device and not activate the device in company, I suggest that you could try to activate it by telephone. Follow these steps:

1. Press Windows logo key + R, type slui 4 in the Open box, and select OK.
2. Select your ___location (or the ___location nearest to you) from the drop-down list, and then select Next.
3. Call one of the available phone numbers listed. An automated system will guide you through the activation process.
4. If you're not able to complete activation successfully, you will be connected to Microsoft support for your region and country.

2.If you' re having this problem on company, the error 0x8007007B usually occurs if you’re not connected to your organization’s network or if you’re having a problem with your Key Management Service (KMS). Here are some steps to try and resolve this:

Check your internet connection: Make sure you’re connected to your organization’s network. If you’re using a VPN, ensure it’s working properly.

Use the command prompt: Open the command prompt as an administrator and type slmgr.vbs /ipk <KMS key>. Replace <KMS key> with the key provided by your organization. After that, type slmgr.vbs /ato to activate Windows.

Use a generic key to activate: If your organization uses volume licensing, you can try to use a generic volume license key to activate Windows. Open the command prompt as an administrator and type slmgr.vbs /ipk <generic key>. Replace <generic key> with the appropriate generic volume license key for your version of Windows. Then, type slmgr.vbs /ato to activate.

You could try to use command below to assign a KMS host to this machine.

slmgr.vbs -skms <kms host ip address> port number

It means that it can't connect to the activation server to get a product key. You can use the following command to generate one.

Run this from admin cmd. And once you get a key enter that in "change product key".
