How to Update Your Windows 10 64 Bit Operating System​

If you want to know how to update your windows 10 64 bit operating system, the answer depends on what you mean by “update.” If you only want the latest Windows 10 patches, use Windows Update. If you mean switching from 32-bit to 64-bit Windows 10, that is not an in-place update, it requires a backup and a clean reinstall of 64-bit Windows 10.

This guide explains both paths clearly so you can choose the right one, avoid data loss, and confirm that your PC is actually running the version you want.

What this guide covers

People often search for how to update windows 10 64 bit when they really want one of two things:

• Install the latest Windows 10 security and feature updates on an existing 64-bit system.
• Upgrade to 64 bit Windows 10 from a 32-bit installation.

Those are not the same process. A normal update keeps your current Windows installation. A 32-bit to 64-bit change requires reinstalling Windows because the architecture cannot be converted in place.

Can you update Windows 10 32-bit to 64-bit?

Not directly. You cannot simply click an update button and convert a 32-bit version of Windows 10 into 64-bit Windows 10. If you want how to upgrade to 64 bit windows 10, you need to back up your files, create installation media, and perform a clean installation of the 64-bit version.

You can, however, update an existing 64-bit Windows 10 installation through Windows Update just like any other supported Windows 10 PC.

Check whether your PC supports 64-bit Windows 10

Before you try to upgrade 64 bit windows 10, make sure the hardware supports it. Most modern PCs do, but older systems may not.

How to check your current Windows type

1. Right-click Start and choose System.
2. Look for System type.
3. You will see one of these labels:
   • 64-bit operating system, x64-based processor
   • 32-bit operating system, x64-based processor
   • 32-bit operating system, x86-based processor

If it says x64-based processor, your CPU can run 64-bit Windows. If it says x86-based processor, it cannot.

What else you should check

• Memory: 64-bit Windows is more useful on systems with 4 GB of RAM or more.
• Disk space: You need enough free space for Windows installation files and your backup.
• Drivers: Check whether the device manufacturer provides 64-bit drivers for your hardware.
• Activation: Confirm your current Windows 10 installation is activated before reinstalling.

Back up your files before you start

If you are changing from 32-bit to 64-bit Windows 10, a backup is essential. A clean install usually removes apps and may erase data on the system drive, depending on how you set it up.

Back up the following:

• Documents, photos, videos, and downloads
• Browser bookmarks and saved passwords, if needed
• Desktop files
• App data you cannot replace easily
• Product keys for paid software, if you need them later

A second copy on an external drive or cloud storage is the safest approach.

Create Windows 10 installation media

To how to upgrade windows 10 64 bit properly, use Microsoft’s installation media rather than downloading random files from third-party websites.

What you need

• A USB flash drive with at least 8 GB of space
• A working internet connection
• Administrative access on your PC

Steps to create a bootable USB

1. Go to Microsoft’s Windows 10 download page.
2. Download the Media Creation Tool.
3. Run the tool and accept the license terms.
4. Select Create installation media.
5. Choose the correct language, edition, and 64-bit architecture.
6. Select USB flash drive as the destination.
7. Let the tool download Windows 10 and prepare the drive.

When finished, you will have installation media you can boot from to install 64-bit Windows 10.

Install Windows 10 64-bit

If your goal is how to update to 64 bit windows 10, this is the step that matters most. The process below performs a clean installation.

Clean install steps

1. Insert the USB installation drive into the PC.
2. Restart the computer and open the boot menu or firmware settings if needed.
3. Boot from the USB drive.
4. When Windows Setup appears, choose your language and keyboard preferences.
5. Select Install now.
6. If prompted for a product key, enter it, or choose I don’t have a product key if your PC is already digitally licensed.
7. Select the correct Windows 10 edition that matches your license.
8. Choose Custom: Install Windows only.
9. Select the system drive or partition where Windows will be installed.
10. Proceed with the install and wait for setup to finish.

After the installation completes, Windows will restart several times. Follow the on-screen setup steps to choose your region, account, privacy settings, and network options.

Important warning about files and apps

A clean install is the standard method for moving from 32-bit to 64-bit Windows 10. It is not the same as a repair update. If you need to keep files, restore them from your backup after setup. Apps usually need to be reinstalled.

How to update an existing 64-bit Windows 10 system

If your PC already runs 64-bit Windows 10 and you only want the latest improvements, use Windows Update instead of reinstalling.

Steps for normal Windows updates

1. Open Settings.
2. Choose Update & Security.
3. Select Windows Update.
4. Click Check for updates.
5. Install any available updates.
6. Restart your PC if Windows asks you to.

This is the correct path if you are looking for how to update windows 10 64 bit operating system without changing the architecture.

Confirm that Windows 10 is now 64-bit

After installation or updating, check that everything is correct.

Verification checklist

• Open Settings and check System type again.
• Make sure it says 64-bit operating system.
• Open Settings > Update & Security > Activation and confirm Windows is activated.
• Check Device Manager for missing drivers or warning icons.
• Open key apps to confirm they launch correctly.

If the system type still shows 32-bit, the installation may have been done with the wrong media or to the wrong partition.

Fix drivers, activation, and app issues

After you upgrade to a 64 bit windows 10 setup, a few common problems can appear. Most are easy to fix.

Driver problems

Some older devices need updated 64-bit drivers. Visit the hardware maker’s support page for chipset, graphics, audio, Wi-Fi, printer, and touchpad drivers.

Activation problems

Windows 10 activation is usually tied to the device, not to whether it is 32-bit or 64-bit. If Windows was already activated on that PC, it often activates again automatically after reinstalling once you connect to the internet.

App compatibility problems

Most 32-bit apps run on 64-bit Windows 10, but very old software or hardware utilities may not. If an app fails, reinstall the latest version from the software maker. For older programs, compatibility mode may help, but it is not guaranteed.

Common problems and solutions

Your PC cannot boot from the USB drive

Check the boot order in BIOS or UEFI, confirm the USB drive was created correctly, and try a different port if needed. Some systems boot more reliably from a rear USB port.

The installer says your CPU is not supported

That usually means the processor is 32-bit only, or the hardware is too old for the 64-bit edition you are trying to install. In that case, you cannot install 64-bit Windows 10 on that PC.

You do not see your files after installation

If you performed a clean install, the files from the old system are not part of the new setup unless you backed them up and restored them manually. Check your backup location before assuming the files are gone.

Windows says it is not activated

Sign in with the Microsoft account previously used on that device, connect to the internet, and wait a little while. If needed, open the activation troubleshooter in Settings.

Some hardware no longer works

Install the correct 64-bit driver from the manufacturer. If no 64-bit driver exists, the device may not be compatible with your new setup.
