In-place Repair Upgrade

(Keeping files and apps)

In-place repair upgrade using Windows ISO file is a good way to fix system errors. Here's how you can perform it.

Download the Windows ISO, preferably from MSDL (Select the version marked with a ❤️ icon). Make sure you choose the ISO that matches your system’s language and architecture.
- To check the installed Windows architecture, open PowerShell as admin and enter,
```
(Get-ItemProperty "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Environment").PROCESSOR_ARCHITECTURE
```
  AMD64/x64 means 64 Bit, x86 means 32 Bit
- To check the installed Windows Language, enter this command,
```
dism /english /online /get-intl | find /i "Default system UI language"
```
  Alternatively, you can use this command,
```
[Globalization.CultureInfo]::GetCultureInfo([Convert]::ToInt32((Get-ItemProperty "HKLM:\SYSTEM\CurrentControlSet\Control\Nls\Language").InstallLanguage, 16)).Name
```
- Note: If you are running the Enterprise LTSC edition, you will need to download that edition's ISO file. Don't download Evaluation version, that can't be activated.
Right-click on the downloaded ISO file, Open With > Windows Explorer
A new DVD drive will appear in Windows Explorer, which means the installation image has been mounted successfully.

Click here for info: Windows 11 on Unsupported Hardware

- If you're using Windows 11 or upgrading from Windows 10, you may encounter errors due to unsupported hardware. - To resolve this, you need to install IoT Enterprise edition which is [officially supported](https://learn.microsoft.com/en-us/windows/iot/iot-enterprise/Hardware/System_Requirements?tabs=Windows11LTSC#optional-minimum-requirements) on unsupported hardware. - To do that, open the command prompt as admin and, - Enter the below command if you are using normal Windows 11 24H2 (or newer) ISO `reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v EditionID /d IoTEnterprise /f` - Enter the below command if you are using Windows 11 LTSC 2024 ISO `reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v EditionID /d IoTEnterpriseS /f` - Now quickly run setup.exe as described below.

- Go into that DVD drive and run setup.exe, just continue until you reach the final confirmation screen. - Make sure it says "**Keep personal files and apps**" on the final screen. Then you can continue the process and wait until it is done.

:::info

If Windows 11 LTSC 2024 is already up to date, performing an in-place repair upgrade requires the latest monthly updated ISO.
Since Microsoft does not provide updated ISO files for LTSC, you will need to manually update the ISO file.
