But the 32-bit version is limited to 4GB of RAM, which will affect the computer's responsiveness. For example, if you run virtual machines, video editing, PS, etc at the same time, your computer may stop working. So, many users may want to convert Windows 11/0 32 bit to 64 bit without losing data and reinstalling programs. Is it possible?

Of course, you can change your Windows 11/10 to 64 bit, but there are something you need to do at first.

How to restore files from backup image after upgrading

After upgrading Windows 11/10 32 bit to 64 bit, there is still one thing you need to do, that is, restoring from backup. here are two situations when recovering files:

1. You only create a system image backup. In this situation, you need a professional software, which support restoring files from system image backup. And it’s not recommended to restore the system image backup, because this operation will restore your computer to previous Windows.

2.  You create a file backup separately. You can directly restore files from backup in Windows 7/8/10/11 using file restore feature.

No matter what situation you are in, you can use free AOMEI Backupper, which offers you 2 ways to restore files, including using Explore Image and file restore feature. Here, I’ll take Explore Image as an example to show you the detailed steps.

Step 1. Launch AOMEI Backupper. Then, click Tools and Explore Image one by one.

Step 5. Go to This PC and the newly added virtual partition, then copy the files you want to restore and paste it into a safe place.

Notes: Please remember to detach the mounted partition(s) you add to your computer. You can open Explore Image and then select the partition you want to unmount, click "Detach".

Wrapping things up

Upgrading Windows 11/10 32 bit to 64 bit, you can only clean install Windows with installation media for Windows 11/10. However, your computer may lose data during the process, so you need to create system backup or file backup at the beginning.

After upgrading to Windows 11/10 64 bit, you could choose to only backup changed files per day automatically, weekly, monthly, or use incremental backup, differential backup. Because continuous backup can protect your system and keep the data up-to-date.
