should I install Windows 10 64-bit? [duplicate]
my laptop has Intel core duo 2 and 3/4 gigabyte ram and came with windows 7 32bit I checked like guides I found said and seams my laptop is compatible with windows 64bit but I think the manufacturer made the decision of installing windows 32bit for a reason
Note that to switch up to 64bit you will need to wipe & clean install. You can only upgrade directly if you stay with the 32-bit Win10.
With only 4GB RAM your experience will probably be better if you stick to a 32-bit OS.
