64 bits are basically compatible with 32-bit software.

32-bit windows cannot use 64-bit software, so if you want to switch to a 32-bit system, remember to download the corresponding 32-bit network card driver in advance, otherwise you can't download other drivers online when installing the machine, and you can only copy them from another computer, which is more troublesome.

To tell the truth, 64-bit is more practical than 32-bit, but it takes up a little more memory. If you feel stuck, you might as well add a memory stick.
