how to stop MS edge from causing problems?

Solution 1:

The easiest way to prevent MS Edge from running is to install another browser, such as Mozilla Firefox, and then set the new browser as the default. Edge should no longer open when clicking on a link.

If Edge still loads on login, you might need to remove edge from Startup and set the Registry to prevent preloading:

• Press Win, type regedit, and press Enter.
• Accept UAC to start Regedit.
• In the Regedit location bar, type, or copy and paste, Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft.
• If the key MicrosoftEdge does not exist, right-click in the left pane on Microsoft, select New > Key` and create it.
• If the key Main does not exist, right-click in the left pane on MicrosoftEdge, select New > Key` and create it.
• If the value AllowPrelaunch does not exist, right-click in the right pane, select New > DWORD (32-bit) Value and create it.
• Double-click AllowPrelaunch and set it to 0 (zero).

This is far more effective than removing Edge, because after each Windows update, Edge would be reinstalled.

Hope this helps!
