How to upgrade ReviOS to a newer version?

Information and Prerequisites¶

For newer versions of ReviOS, we provide 2 separate ISOs. One for installing a brand new ReviOS instance and one for upgrading a previous ReviOS version. This way, users can update their ReviOS instances without reinstalling and losing files.

Danger

This is an experimental approach. The upgrade has been tested multiple times, but we obviously cannot cover all edge cases, So please use with caution!

This method will only work if upgrading from a previous ReviOS installation on at least the 21H2 Windows version or stock Windows (but is preferable for a complete fresh install). From other Customizations Adjustments System upgrades neither work nor are supported. Cross-upgrading, say from ReviOS 10 to 11 or vice versa, should work, but has not been tested.

And the partition (often called) that you install ReviOS on requires at least 20-25 GB of free space. C:

Step 1: Download ISO¶

Download the latest Upgrade for ReviOS 10 or 11 from the Downloads page of our website Version.

Make sure to download the Upgrade option.

Confirm¶

In File Explorer, go to the location where you downloaded the ISO file and press Shift in an empty space of the window Right-clickOpen PowerShell window here and select. Enter the following command:

1个	Get-FileHash -Algorithm MD5 -Path

And replace the <file name></file> part with the name of the ReviOS installer file. You can autocomplete file names using the Tab button. For example: Get-FileHash -Algorithm MD5 -Path .\ReviOS-10-22.10-Upgrade.iso

When the command returns the hash value of the file, compare it with Revision Compare the corresponding MD5 hash values ​​on the verification page on the website. If they match, it means the ISO file is not corrupted and you can continue with the process.

Step 2: Preparation¶

First, you must extract the ISO file files on the partition where ReviOS is installed. By mounting the image and copying the files out, or using file archiving software such as 7-Zip.

This is important because the upgrade process will not work if it is just run from the mounted ISO.

Another situation where this might not work is if you extracted the ISO to a USB or network mounted drive.

So please make sure the file is on your PC . The easiest way to do this is to do this on the root of your Desktop or Windows partition, often called C:.

Step 3: Get Started¶

Now all you have to do is run the upgrade.bat file. If you don't have an upgrade.bat file, just run setup.exe. Likewise, if errors are returned with the bat file, such as missing telemetry parameters.

The following should open. If not, see possible issues

Here, just complete the default settings the installation provides you. (Next, Accept, Install)

on hardware without TPM and SecureBoot

setup.exe

When upgrading, your operating system will restart multiple times.

Possible Issues¶

If the error Unable to create required installation folder // Error code: 0x8030002F occurs and you have followed the tutorial, Restart usually solves the problem.

If restarting does not resolve the issue for you, you may be affected by a problem with Windows itself. You can try the following steps in order.

1. If you have previously copied files from a mounted ISO or using WinRAR, please try extracting using 7-Zip and then upgrade.batrun it again .
2. Run setup.exe directly instead of using upgrade.bat. And choose not to install updates, although this setting does not seem to affect the ReviOS upgrade.
3. Try Step 1 in this tutorial. This must be a last resort as it will provide access to the internal folders to everyone and everything. LocalAppData

If none of these steps resolve the issue, you must perform a clean installation. Upgrading does not work on your machine.

Step 4: Once you have completed the upgrade, the operating system will run through its preparations again, just like after a clean installation. By default, ReviOS does not delete the Windows.old folder as some users prefer older versions. To clean it, you can run Disk Cleanup as administrator and select
