The Windows XP professional operating system comes in two different formats, these are; Windows XP 32 bit and Windows XP 64 bit. When you are using a 32 bit operating system, it means that your computer has smaller 32 bit size. This will give rise to more bottlenecks which can eventually slow down your system as a process needs to wait for the other process to finish, before beginning. Alternatively, you are restricted to a maximum of 4 GBs of RAM on a 32 bit operating system, and when it comes to 64 bit OS, there is no such limit.
If you are currently using the 32-bit version of the Windows XP operating system, you may upgrade it to the 64 bit version if your computer has a 64 bit processor. In this process, you will need to install the 64 bit operating system over your currently installed 32 bit operating system. So ensure that you back up your data that you don’t want to lose, or else there is a chance that it may get erased during the installation.
Microsoft help instructions to upgrade Windows XP 32 bit to Windows XP 64 bit
