To downgrade Windows 10 Pro to Home without losing data, you can follow these steps:
Prerequisites:
- A Windows 10 ISO file of the same or higher release from the Media Creation tool.
- Some command-line experience.
Step 1: Change the Registry values
- Right-click on the Start button and select “Windows PowerShell (Admin)”.
- Paste the following command and press Enter:
Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows NT\CurrentVersion" -Name EditionID -Type String -Value Core;Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows NT\CurrentVersion" -Name ProductName -Value "Windows 10 Home";Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows NT\CurrentVersion" -Name CompositionEditionID -Value "Core"
This command changes the registry values in the current version from “Pro” to “Home.”
Step 2: Download the Windows 10 ISO file
- Go to the Microsoft website: http://go.microsoft.com/fwlink/?LinkId=691209
- Choose “Create Installation Media for this PC.”
- Select the desired options for Windows 10 Home (standard ISO file) and language.
- Choose “ISO File” and save the ISO file.
Step 3: Perform an IN Place Upgrade
- Open the downloaded Windows 10 ISO file and run “Setup.exe.”
- Change the settings so that updates aren’t downloaded during the installation process. ( Not Update)
- When prompted, select “Keep personal files and apps.”
The upgrade process will start, and it may take up to 30 minutes on a standard PC to complete. After the installation is finished, you should have Windows 10 Home with your personal files, apps, and settings intact.
If you had an existing license for Windows 10 Home, it should be automatically activated as the downgrade retains your digital license. However, if you do not have a valid license for Windows 10 Home, you may need to purchase one from Microsoft to activate your operating system.
