Press and hold the Windows key and the Pause key, or open the System icon in the Control Panel.Below is a picture and an example of this window.ĭetermine if Windows XP is 32-bit or 64-bit The System window, next to System type, lists 32-bit Operating System for a 32-bit version of Windows and 64-bit Operating System if you're running the 64-bit version.Instead, the Pause key is a secondary function of a function key, and you need to press the Fn key and that function key. The actual limit is often less than around 3.5 GB since part of the register is used to store other temporary values besides memory addresses.Some laptops don't have a Pause key. One bit in the register can reference an individual byte in memory, so a 32-bit system can address a maximum of 4 GB (4,294,967,296 bytes) of RAM. The CPU register stores memory addresses, which is how the processor accesses data from RAM. Most computers made in the 1990s and early 2000s were 32-bit machines.
