You can only upgrade your 32 bit version of Windows 7/8/8.1 to 32 bit Windows 10, because Microsoft only allows you to upgrade from a qualifying version to its equivalent edition on the same architecture.

But the 32-bit version is limited to 4GB of RAM, which will affect the computer's responsiveness. For example, if you run virtual machines, video editing, PS, etc at the same time, your computer may stop working. So, many users may want to convert Windows 10 32 bit to 64 bit without losing data and reinstalling programs. Is it possible?

Of course, you can change your Windows 10 to 64 bit, but there are something you need to do at first.

2. Backup system including personal files and folders. To upgrade Winows 10 home or Professional 32 bit to 64 bit, the only way is to clean install the operating system and reconfigure all your settings. However, this operation will remove all the data and programs on the system disk. So, it’s necessary to create a system image for your computer.
