As with storage specifications, Windows 10 would also have to be able to run on your PC. This means that some basic system specifications must be met.
The specifications for running Windows 10 are relatively low: a 1 GHz or faster processor; 1 GB (32-bit) or 2 GB (64-bit) RAM; 16 GB of free storage space; a Microsoft DirectX 9 graphics device; and an Internet-enabled Microsoft account.
Go to the Control Panel to find out the specs of your PC and choose System and Security, then System.
However, bear in mind that these are the basic requirements, and to have a smooth and pleasant experience, you can shoot for higher specs.
