KB5034230: Compatibility update for installing and recovering Windows Server 2016: January 9, 2024

WinREAgent logs events related to the Windows Recovery Environment (WinRE), primarily recording details about the creation, modification, and usage of the recovery image. In this case, we are looking for Event ID: 4501 Servicing succeeded events. If you are unsuccessful in locating WinREAgent servicing events because of space limitations that might occur in your environment, we suggest you use the DISM command. 

1. Open the Windows Search bar. To do this, right-click Start and then click Search.

2. In the Search bar, type Event Viewer and then click Event Viewer.

3. Expand Windows Logs and then click System.

4. In the right-side navigation pane, under Actions, click Find.

5. In the Find what: box, type WinREAgent and then click Find Next.

6. Click Cancel to close the Find dialog box. The WinREAgent servicing event should be shown in the bottom middle pane and you should see a message similar to the followng on the General tab:

   Servicing succeeded. The Windows Recovery Environment version is now: 10.0.22621.4742

   The WinRE version in this example is 10.0.22621.4742.

4. At the command prompt, use the DISM command to retrieve the Windows Recovery Environment (WinRE) information. For this example, enter the following command and then press Enter:

   Dism /Get-ImageInfo /ImageFile:\\?\GLOBALROOT\device\harddisk0\partition5\Recovery\WindowsRE\winre.wim /index:1
