Windows 10: Why isn't windows letting me use all my ram?

So I recived a computer as a present prom my grandma this Christmas. I've been playing a game on roblox named Grand Piece Online. This game is very deatailed and requires a lot more ram than your average roblox game. When im in the game in only running 30-45 frames, and my stats on the game say that my memory maxes out at 1300mb of memory. This is incorrect given that my system after running the game still has 2gb if ram left. How do i maximize/ use my computer to the fullest because i really do need to squeeze out some better frames and better graphics with what I have. I know this is a windo

Printer isn´t working after latest update.

After the latest update from Windows, my Canon Pixma ip6600 printer isnt working. In Device Manager it shows up as working properly but when I go to print it isn´t listed as an option in any programs. Troubleshoot suggests it´s a USB 2 printer on a USB
3 port and that that´s the problem but that cant be since it worked fine before the update. I´ve tried to uninstall and plug it back in but that doesn´t work either.

 

Cortana isn´t working

When I hit enter, it did something, but there´s still no Cortana, even after restart. So I tried it again, but now it says that it failed, because it´s already installed and it´s working in PC. So it should work, but Cortana still isn´t here.

 

Printer isn´t working after latest update.

Managed to solve it... here´s how I did it just in case anyone else has the same problem...

->Settings

->Printers & scanners

->Add a printer or scanner

->The printer that I want isn´t listed

->Add a local printer or network printer with manual settings

->Use an existing port: USB001 (Virtual printer port for USB)

->Choose printer

->Use the driver that is currently installed

->Type printer name

And done... =P
