Consider that installation again, is it worth to do that change at all — if your computer has 4 GB (or less) your existing 32-bit system will be less resource hungry, since its „words” are 4-byte long, not 8-byte.
I've got as my other computer Orange Pi 800 — and I'm considering exactly the opposite: replacement of its 64-bit „factory installed” OS with 32-bit variant (for the reason above).
