On my Windows 11 work PC, I used to have to close them all to free up enough RAM to properly run my CAD. Now that I have 64GB I don't have to do that so much anymore, but still... Before the upgrade, between Windows caching every system file in-RAM and chrome being the terrible RAM hog we all know it to be, that otherwise top-of-the-line laptop performed as poorly as my 2017 personal laptop.
