Hi
Well every one is going to have to update to Windows 10 one way or another, if not now then when they get a new computer.
I just figure that I might as well get into it from the start.
They are updating it a lot because it still has things that need to be fixed unfortunately, I suppose that eventually they will slow down.
Are you sure that your computer supports 64 bit, if it does it should have had a 64 bit on it to start with.
I haven't seen any manufacturers shipping 64 bit computers with 32 bit operating systems.
What version of Windows 10 are you running Home, Pro, you have to match what you have.
Set Windows to notify you of updates, but not to install them until you want it to.
Then you won't be interrupted by forced...
