Microsoft gives you the 32-bit version of Windows 10 if you upgrade from the 32-bit version of Windows 7 or 8.1. But you can switch to the 64-bit version. Why upgrade windows 10 32 bit to 64 bit? 

The reason is that the 32-bit version is limited to 4GB of RAM, which is a small amount. Especially when these days PCs usually have 8GB or more. If you upgrade your computer to 64 bit, you'll be able to run more applications simultaneously. Other applications like Google Chrome will be able to handle more open tabs, and you will be able to run more memory-intensive applications, such as AutoCAD, Photoshop, and video editing programs, etc.

However, during the period of changing to 64 bit, most people complain that their files got lost. Follow the three steps below to change Windows from 32 bit to 64 bit without losing data!

1. Make Sure 64-Bit is Compatible with Your Processor

You can only install the Windows 64-bit on compatible hardware, that is to say, you have to make sure if your computer has a 64-bit processor. Here we only provide the easiest way for you to check your system type:

  • Open the "Start menu".
  • Search for "System Information".
  • Press "Enter".
  • Look for "System Type".

Then, you will see one of the following system types:

  1. 1. 64-bit operating system, x64-based processor: Your CPU supports 64-bit and you have already installed the 64-bit version of Windows 10. So you don't need to upgrade.
  2. 2. 32-bit operating system, x64-based processor: Your CPU supports 64-bit, but you have installed the 32-bit version of Windows.
  3. 3. 32-bit operating system, x86-based processor: Your CPU supports 32-bit and you have installed the 32-bit version of Windows.

If you see the second type, then your computer can run a 64-bit version of Windows. If you see the third one, it means you can't install another architecture of the operating system because your CPU doesn't support it.

2. Back Up Important Files Before Windows 10 64-Bit Upgrade

To avoid data loss, you'd better make a full backup of your PC.
