How to Fix Windows Activation Error 0x803F700

1. Check Network Connection

During operation, your computer communicates with the Microsoft activation server to transmit data and verify your Windows license. If you have issues with an unstable Internet connection, this communication process will not be able to occur, leading to similar situations as the current one.

If possible, you can try switching to a different Wi-Fi network and then perform the initial troubleshooting steps again. There are also other different ways to fix network issues that you can try to resolve the problem.

2. Disable Firewall and Security Software

If your network connection is stable and working fine, the next step you can try is to disable the firewall or third-party security software. These applications usually block the communication between your computer and the Microsoft activation server.

This often happens when the firewall or security program misinterprets information related to the activation process and sees it as suspicious or unauthorized activity.

3. Verify Date and Time

During the activation process, using timestamps as milestones to notify the server when events occur is common. If the time on your computer is not synchronized with the server’s time, the activation request may be denied.

Here’s how you can adjust the date and time on your computer:

Step 1: Press the Windows + I key combination to open the Settings panel → Click on Time & language.

Step 2: Click on the Date & time tab → Toggle the switch to the right to turn on the Set time automatically and Set time zone automatically features.
