You can run Win on Linux through VBox (there are others, but I haven’t used them before) without having to reboot. Win actually boots/runs FASTER on Linux in VBOX than if you actually rebooted (and ran) to Windows.
Yeah I’ve run Win in virtualbox but never did figure out how to get USB ports working which I’d need for my auto repair info and scantool along with special drivers for the scantool usb adapter so I said screw it. I can reboot in under a minute since Kubuntu shuts down in about 5 seconds. This Thinkpad W530 + Kubuntu with Plasma desktop is the fastest most stable system I’ve ever run.
BTW, KDE made a lightweight browser called Falkon. Pretty basic but pretty fast. Supposed to use less resources than firefox/chrome. Whatever extensions are available are built in and you just enable/disable them and one of them is Adblocker. I haven’t bothered importing bookmarks or anything. I use it mostly for streaming video. Does well with that.
