Can you upgrade Windows 7 32 bit to 64 bit?
It's no surprise that many users want to upgrade Windows 7 32 bit to 64 bit. The benefits of using a 64-bit operating system are most apparent in performance when you have a large amount of random access memory (RAM) installed on your computer, typically 4 GB of RAM, up to 16 TB. However, the maximum RAM limit for Windows 7 32-bit is 4GB. Here is an example from Microsoft.
“I'm running windows 7 32 bit but I want to upgrade to 64 bit. And I want to keep all my data and software safe. Can I upgrade Windows 7 32 bit to 64 bit without losing data? Will this cost me anything or is my product key still valid for windows 7 64 bit?”
However, in all version or edition of Windows (XP/Vista/7/8/10, Home/Pro/Ultimate/Enterprise), there is no “Upgrade” option that can directly upgrade to 64 bit. Therefore, you could consider using clean install to install 64 bit operating system and then restore files you will use in the near future, so that you can upgrade Windows 7 32 bit to 64 bit without losing data. The premise is that the current computer is compatible with 64-bit operating system. The entire process is below.
Step 1: Check the current hardware’s compatibility
Check system type of your computer
To make sure you can successfully clean install Windows 7 64 bit, the first thing is to check the system type of your computer. If the system type is x64-based PC, you can upgrade Windows 7 32 bit to Windows 7 64 bit. If the system is x84-based PC, you cannot upgrade your Windows.
To check system type:
1. Open the Start menu.
2. Search for System Information and press Enter.
3. Look for System Type. If the system type is x64-based PC, you can upgrade Windows 7 32 bit to Windows 7 64 bit. If the system is x84-based PC, you cannot upgrade your Windows.
Note: The system stype can also be displayed as follow. You just need to check if your computer supports 64 bit processor. If it is, you can perform Windows 7 32 bit upgrade to 64 bit.
• 64-bit operating system, x64-based processor
• 32-bit operating system, x64-based processor
• 32-bit operating system, x86-based processor
Verify CPU and driver compatibility
To further determine that you can upgrade Windows 7 32 bit to 64 bit without format, you need to verify CPU compatibility and driver compatibility.
To check CPU compatibility, you can download Coreinfo from Microsoft, then see if the processor include Physical Address Extension (PAE), No-eXecute (NX), Streaming SIMD Extensions 2 (SSE2), CMPXCHG16b (CX16). To make it, type coreinfo in the command line window and press Enter, then hit Ctrl + F and type PAE, NX, SSE2, CX16 one by one.
To check driver (eg: graphics and sound cards) compatibility, you can go to device manufacturer support website and see if you can find 64-bit versions of the drivers.
After checking these compatibility, you may already know if your computer is compatible with Windows 7 64-bit system. If it is, please continue to see below and learn how to upgrade Windows 7 32 bit to 64 bit without losing data.
Step 2: Backup your computer to protect data and system
Before upgrading Windows 7 32-bit, you still need to make a system image backup for your computer.

The way forward
Clean Install is the best way to upgrade Windows 7 32 bit to 64 bit.
