Hi,
Firstly, you need to determine that your device features a 64-bit processor, at least 2GB of RAM, and whether the rest of the components have support for 64-bit drivers.
Open Settings-system-about, under the "Device specifications" section, check the System type details.
Once you complete the steps, if "System type" reads 32-bit operating system, x64-based processor, then your computer is running the Windows 10 32-bit version on a 64-bit processor. However,
if it reads 32-bit operating system, x86-based processor, then your device doesn't support the 64-bit version of Windows 10.
Then you could refer to the following link to change versions:
