It must be her computer that is slow..or internet connection. I,ve had windows 10 since it was released and my web pages open super fast. .
Don't know...the computer is fairly new ( less than 4 yrs old ) , her internet is fibre to the house.
My old win 7 has a home page full of tiles...I pick a tile ( like my swag ) and after finishing with it, close it and then pick another tile.
On my other laptop with Win 10...I can get a screen with tiles on it, but not the home screen ? The screen with tiles on it are found by using the windows button, but if I close a website, it goes back to the home screen....so a crap idea for me ..
As for performing formats and cleaning the system, for the average joe blow, that stuff is not explained to them and certainly not shown to them .
