Is Windows 10 Creator's Update supported?

Procedure to upgrade Windows 10 to Windows 10 1909 or 21H1 or newer build numbers.

As the Windows 10 versions are important upgrades, Microsoft doesn't provide direct links to download the upgrade files for 1909, 21H2,et.. they instead provide an ISO file to download. As a result Shavlik cannot supply the URL to download the ISOs automatically, so the user must do this step manually and supply the ISO to the Patch Manager.
The following focuses on 1607 but it also applies to 1703 and probably following.

1. Create the Windows 10 update ISO file :

Note: In case of upgrading Windows 10 Enterprise, ISO needs to be downloaded specifically from MSDN or Volume Licensing downloads. (This has been confirmed by Ivanti).

There are two ways to proceed, method 1 being the easiest:

1. Download the ISO file directly from the MSDN website if the MSDN account is present. The Multiple Edition ISO files work too.
2. If MSDN account is not present then open a session on a Windows 10 device, download the ISO by using the Microsoft tool MediaCreationTool.exe available from this URL

If the second method is used (the MediaCreationTool.exe method), then follow these steps to download the ISO file:

- Launch the tool then select "Create installation media for another PC":

- Select the Language, the Edition and the Architecture:

- Choose "ISO File":

- Save the Windows.iso file

2. The version number of the Windows.iso that got downloaded could  be found by following below steps :

• Mount the iso

• It loads as a drive

• Check the Product version of the Setup.exe  eg if the Product version :10.0.17763.1 the the iso that got downloaded is Windows 10 Version 1809

3. Rename the ISO file:

The iso file needs to be renamed as per Shavlik's recommendation. To do so, follow below screenshot:


Go to Patch Manager>Service Packs by Product>Right click on the SP and select ‘Display ISO file names'.

4. Copy the ISO file to the Patch Repository :

The patch repository is used to store patches that must be moved to another disk or that were downloaded by other ways.
- Check if a patch repository has already been configured on the Patch Manager:

 If no patch repository has been set yet, set one. The patch module will always look in this folder prior to downloading any patch. If the patch it's looking for is there it'll use it as if it had been download by itself.
- Copy/move the ISO files to this folder

5. Create a Patch Group :

- Create a new Patch Group
- Select "Service Pack Only" then select the Windows 10 version 21H1 Service Pack:

 
 - Add the affected devices corresponding to the Windows 10 to upgrade:

 
 - Select the languages, the ISO file(s) added in the repository must correspond to the selected language(s):

- It is important to uncheck the option "Only Reboot if Requested by Patch", because the device must reboot after the first installation step of the upgrade in order to continue the other steps of the installation after the first reboot.
