How to Check if Windows 11 is 32-bit or 64-bit
🔔 Good to know: Windows 11 only comes in 64-bit. There is no 32-bit version. When you check, your system type will always show 64-bit operating system — or ARM-based processor if you're on a device like the Surface Pro X or a Copilot+ PC.
To confirm:
- Click Start > Settings > System > About.
- Under Device specifications, look at the System type field.
How to Check if Windows 10 is 32-bit or 64-bit
🔔 Important Note: Microsoft ended support for Windows 10 on October 14, 2025. Your PC will still work, but it no longer receives security updates. For the best protection, consider upgrading to Windows 11 if your device supports it.
To check your system type:
- Click Start, then select Settings.
- Click System.
- Go to About and look for the System type field.
How to Check if Windows 8 is 32-bit or 64-bit
🔔 Important Note: Microsoft ended support for Windows 8 and 8.1 on January 10, 2023. We strongly recommend upgrading to a supported version of Windows to keep your PC secure.
On Windows 8:
- On the Start Screen, type computer — the search will open automatically.
- Click Computer, then select Properties. Your bit version is shown under System.
On Windows 8.1:
- Right-click This PC, then select Properties.
- Your bit version is shown under System, next to System type.
How to Check if Windows 7 is 32-bit or 64-bit
🔔 Important Note: Microsoft ended support for Windows 7 on January 14, 2020. Running an unsupported OS puts your PC at risk — please upgrade to a supported version of Windows.
To check your system type:
- Click the Start menu.
- Type system into the search box and select System from the Programs list (don't press ENTER right away).
- The System type field will tell you your operating system's bit version.
The Difference Between 32-bit and 64-bit
A 32-bit PC processes data in smaller pieces, which can limit performance and software compatibility. A 64-bit PC processes larger chunks of data, often leading to better performance and the ability to use more memory (RAM). Like having the right-sized shoes, the correct bit version ensures your software runs smoothly on your PC.
You may also see ARM-based processor on newer Windows devices (like Copilot+ PCs and Surface Pro X). ARM is a different processor architecture — not a "bit" version — but Windows still runs many 64-bit apps on it through built-in emulation.
Can You Switch Between 32-bit and 64-bit Windows?
Switching from one bit version to another is a substantial change, a bit like moving to a new house. It requires reinstalling your operating system, which means backing up your data and possibly getting technical help. If in doubt, it's usually best to stick with the version your PC came with — or, if you're upgrading hardware, let Windows install fresh on the new device.
Quick Tips Before You Install Software
- Check software requirements — before installing anything (including Trend Micro Security), confirm it's compatible with your system's bit version.
- Use official sources — download installers from official or reputable sources to minimize the risk of malware.
- Back up first — always back up your important files before making system changes.
