Is it possible to change a 32 bit system to a 64 bit one? (Cm)
You can install a 64-bit system. Just give it to you? With 4 gigabytes of RAM, the new system will not give you a performance boost. It may even slow down the system. If you want a 64-bit system, add some RAM first. By the way, it will be very useful to you for games.
Based on the screenshots of your system, you can install a 64 bit system by reinstalling Windows
