If you’re still using a 32-bit version of Windows 7, 8, or even older versions of Windows, the chances are that you will be running out of memory faster than you would like. Thankfully, there is a solution; upgrading your machine to 64-bit.

A 64-bit operating system is an advanced version of an operating system that can access more than 4GB of RAM on a computer. It is important that you check whether your OS is 32-bit or 64-bit before you proceed to perform any upgrades.

Why should I upgrade from 32-bit to 64-bit?

There are good reasons to upgrade from 32-bit to 64-bit Windows. For example;

  • More memory – A 64-bit operating system is capable of addressing much more memory than a 32-bit system, thus allowing you to work with large files without having to worry about running out of memory. 
  • Faster processing – With the 32-bit version, you are limited to 4GB of RAM, but with the 64-bit version, you can use up to 16 exabytes of RAM. This means that your computer will be able to run programs faster and more efficiently.
  • Greater stability – Upgrading from 32-bit to 64-bit actually makes your system more stable because it uses less memory than before. 
  • Improved compatibility – Most modern hardware is designed for 64-bit platforms, so upgrading from 32-bit to 64-bit will allow your system to take full advantage of the newer technology available today.
  • More security – Because a 64-bit operating system can use more than 4GB of RAM, it is less vulnerable to attacks from malware that exploits memory holes or other vulnerabilities.
  • Better performance – You’ll see an overall improvement in how quickly your computer responds to your input because programs will run faster and use less CPU capacity while they’re running.

Can I upgrade from 32-bit to 64-bit?

To upgrade from 32-bit to 64-bit, you need to make sure that your system meets the minimum requirements for the 64-bit version of Windows. Among other questions you should ask yourself include:

  • Do I have more than 4GB of RAM and do I use more than 4GB of RAM?
  • I’m I using high-resolution monitors or virtual machines?
  • Do I use applications that make use of multiple cores?

To check for compatibility, follow the steps below:

  1. Click on the Start menu and search for System Information.
  2. Locate System Type and if it reads x64-based PC, you can upgrade to 64-bit.

You also need to ensure that your CPU and drivers are compatible with the 64-bit. For drivers, check your manufacturer’s website and look for the 64-bit driver versions.

To check CPU compatibility:

  1. Hit the Start icon, type cmd, and select Run as administrator.
  2. Type in set pro and click Enter.
  3. You should now be able to tell whether your processor is compatible.

Can I install 64-bit Windows on 32-bit?

Yes, you can install 64-bit Windows on a 32-bit system but you shouldn’t. While it’s possible to install a 64-bit version of Windows on a 32-bit machine, it’s not recommended because of compatibility issues with some software and hardware.

This isn’t a supported configuration and may cause problems down the line. 64-bit software can’t run in 32-bit mode, so if you try to run 64-bit apps on your computer, they’ll crash.

There are also some important limitations to keep in mind:

  • You can’t run 32-bit applications on the 64-bit version of Windows. It’s easy to differentiate a 32-bit app from a 64 bit.
  • Some drivers will only work with the 32-bit version of Windows.
  • The 64-bit version of Windows may not support all hardware components of your computer’s hardware configuration such as video cards or network adapters.

And that’s how to easily upgrade from a 32-bit version to a 64-bit in Windows 7. We also have a trick up our sleeves on how you can continue using Windows 7 forever if you are not a fan of the latest iterations from Microsoft.

If you’re still on the fence, we have a comprehensive comparison of Windows 11 vs Windows 7 to help you make an informed decision.
