Hi. My name is***** you for your question and the opportunity to assist.
Do you have the same slowness using the Edge
You can go here: www.mozilla.org
and download Firefox to see if there's a performance difference.
This site is optimized for Firefox. Try it and see if it makes a difference.
Do this on your PC.
Right-click the Start button and select Command Prompt (Admin)
At the blinking prompt in the black Window type the following commands, pressing Enter after each:
netsh winsock resetnetsh int ipv4 resetnetsh int ipv6 resetipconfig /releaseipconfig /flushdnsnetsh int ip reset netshlog.txt
Restart the machine when finished. What this does is resets the networking protocols in Windows.
