- Could you take a screenshot of the following pages in task manager: Processes (Sort Memory by the highest amount first (Arrow need to be pointing down) by pressing on the box named "memory") and Performance.
- Basic system requirements for windows 10 mentions 2 GB ram for 64bit, Windows 10 system requirements (microsoft.com) Today i would suggest a minimum of 8GB at minimum use and 16 GB would be a sweet spot, i'm using 16 GB.
I have tried running Windows 10 32Bit on a computer with 2 GB of ram, the requirements for 32 bit is 1 GB. First of all, not a great experience, slow and could not run stable.
But try sharing the information above, it may be that something is really using a lot of ram.
