Install-MSUpdates - .Cab file support suggestion

Topics: Archive - General
Dec 22, 2014 at 9:31 AM
Here is a modified 3.5.0 Install-MSUpdates function with .cab file support - I'm sharing as this might be useful addition for future toolkit version?

Occasionally MS updates are found in .cab format (WSUS etc) - I recently needed to implement this for an IE 11 distribution..

I also found it necessary to also add -WorkingDirectory "." to the execute-process commands in the function to get updates to work for me in 3.5.0

Thanks for the toolkit - keep up the good work!
