Getting information about the winRE.wim recovery image is not working for us

[hotzenwalder]

We manually executed the script on a Windows 10 system with build 19045.5608. Windows is using the language nl-NL and is licensed with a Enterprise license or a Business Premium license.

When the part is ran to discover more information about the recovery image in C:\Windows\System32\Recovery\WinRE.wim, we get the errors as seen below.

There is no WinRE.wim file located in C:\Windows\System32\Recovery. Should there be a file?
The complete logfiles are here. They might help in troubleshooting.

We made a slight modification to the script on line 978

We changed
if ($folder.Name -match '^[a-z]{2}-[A-Z]{2}$' -and $folder.Name -ne 'en-US') {

to

if ($folder.Name -match '^[a-z]{2}-[A-Z]{2}$' -and $folder.Name -ne 'en-US' -and $folder.Name -ne 'nl-NL') {

Interesting, I had not accounted for making it easy to expend beyond US English. I will likely add a variable for this. Can you please check C:\winre_backup to see if there is a .wim in there? I've had some issues with this particular bit of code since I replaced the function that was simply a Microsoft provided script with my own code in version 17.0. Let me dig through your logs a bit and I will get back with you.

Can you please check the version of the script that these logs came from and tell me if the variable for the script version is $version or is it $ScriptVersion? This is around line 170. I accidently used $Version for two different things and that broke things. This was corrected last night.

Version 22 adds a $PreserveLanguages variable (comma separated list), fixed the issue with $output, improved logic for all WinRE operations, including better backup and restore and skipping all WinRE operations when deemed unsafe to perform them. Let me know if this solves your issues.

@PowerStacks-BI thank you for fixing the issue. Could you make $PreserveLanguages a Parameter? This would make setting the variable way easier.

The script that generated the errors had this on line 170

[int]$ScriptVersion = 21.2

The only error left when we are running this manually is

I believe that this issue has been resolved. I accidentally used $Version for two totally different things. Try version 25 please.
