I am also Windows user. Let us work together to sort this out.

You can try the following steps below.

Run the Network Adapter troubleshooter
To run the Network Troubleshooter
• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 2
Try to reset the Network Adapter
You can also try to perform a Network Reset to resolve the problem. This will reset the entire network configuration including your IP address. To perform Network Reset, follow these steps:
• Tap the Win + I keys to open Settings.
• From there, go to the Network and Internet section.
• Next, scroll down and look for “Network Reset” under the status pane.
• After that, click on Network Reset and then on Reset now to start resetting the network configuration.

Option 3
• Tap the Win + X keys or right click on the Start button and select Command Prompt (Admin) or you could also search for “cmd” in the Cortana search box and right click on Command Prompt from the search results and select the “Run as administrator” option.
• If a User Account Control appears, click on Yes to proceed. After that, type each one of the commands listed below and don’t forget to hit Enter after you type each one of them.
o netsh winhttp reset proxy
o net stop wuauserv
o net start wuauserv
• Now restart your computer and check if the problem is fixed or not by installing or updating Microsoft Edge again.
