Yes, it's possible that the issue could be related to regional settings or restrictions. Sometimes, the availability of certain features like phone activation may vary based on the region or country you are in.
Using a VPN (Virtual Private Network) to change your IP address and connect to a server in a different region may help resolve the issue. By connecting to a server in a region where phone activation is supported, you may be able to access the correct dialog box for phone activation.
Here's how you can use a VPN to change your region:
1. Install a VPN client: Choose and install a reputable VPN client that suits your needs. There are many options available, both free and paid. Make sure to choose one that supports the region you want to connect to for phone activation.
2. Connect to a server in the desired region: Open the VPN client and select a server in the region where phone activation is supported (e.g., United States, United Kingdom, etc.). Follow the instructions provided by your VPN client to connect to the server.
3. Open the "Activate Windows" dialog box using "SLUI 4": Once connected to the VPN, open the Run dialog box by pressing the Windows key + R, then type "SLUI 4" (without quotes) and press Enter. This should launch the "Activate Windows" dialog box specific to the region you connected to, allowing you to activate Windows via phone support.
Please note that using a VPN and changing your region to activate Windows may not always be allowed or supported by Microsoft. It's advisable to use a VPN service that complies with the terms of service and doesn't violate any licensing agreements.
If using a VPN does not resolve the issue, I recommend contacting Microsoft support directly for further assistance. They will be able to provide you with the most accurate information and guidance based on your specific situation.
I hope this helps, and best of luck with your Windows activation!
