I thought my laptop was slow when i and Firefox (it is also slow on Chrome) but i started to use microsoft edge. web pages load faster. youtube and fals based video websites work faster and my laptop is no longer sluggish
Sorry to break it to you but Microsoft Edge is shit. You may want to remove some startup services or just clear your history and cache.
Use a privacy respecting and oriented browser like brave, its a fork of chromium without all the other junk has it's own ad blocker part of it and install the addon ublock origin.
Thanks me later!
Actually the latest version of Microsoft Edge works much better than Google Chrome on a Windows Laptop or computer. I tried streaming some sports games using Chrome and there always seemed to be a pause and go, pause and go.... that was annoying. With Microsoft Edge it was perfect, just like your 4K TV.
