32 or 64 bit

My suggestions rely upon what you have installed. If you currently have 32 bit Windows installed, use 32 bit Windows 10. If you have 64 bit Windows, use 64 bit Windows 10.

This is to ensure a smooth migration, especially where driver compatibility is concerned. Another factor is RAM. If you have max 3 GBs of RAM, then 32 bit should be sufficient for your needs. If you happen to have 4 to 8 GBs or more RAM, then 64 bit would be suitable.
