Ever wondered why Windows Server Update Services (WSUS) offers Flash updates for Windows Server? Adobe Flash Player is installed on Windows Server 2016 / 2019 if you have the Remote Desktop Session Host (RDSH) role installed. Yikes! I can imagine you want to delete Adobe Flash Player without deleting the RDSH role, and here is how.

You can easily uninstall and remove Adobe Flash Player from Windows Server using Deployment Image Servicing and Management (DISM):

DISM /Online /Remove-Package /PackagePath:"C:\Windows\servicing\Packages\Adobe-Flash-For-Windows-Package~31bf3856ad364e35~amd64~~10.0.14393.0.mum"

If you want to, or have to, install Adobe Flash Player on Windows Server 2016 again, use:

DISM /Online /Add-Package /PackagePath:"C:\Windows\servicing\Packages\Adobe-Flash-For-Windows-Package~31bf3856ad364e35~amd64~~10.0.14393.0.mum"

If you happen to still be on Windows Server 2012R2, you can use the following command to remove Flash Player:

DISM /Online /Remove-Package /PackagePath:"C:\Windows\servicing\Packages\Adobe-Flash-For-Windows-Package~31bf3856ad364e35~amd64~~6.3.9600.16384.mum"

And for Windows Server 2019:

DISM /Online /Remove-Package /PackagePath:"C:\Windows\servicing\Packages\Adobe-Flash-For-Windows-Package~31bf3856ad364e35~amd64~~10.0.17763.1.mum"

Basically the only difference is the build and version number.

If you then want to completely remove Internet Explorer (IE) from Windows Server, use the next command:

DISM /Online /Disable-Feature /FeatureName:Internet-Explorer-Optional-amd64
# use `DISM /Online /Get-Features` to list all enabled features

Or you can use Disable-WindowsOptionalFeature to uninstall Internet Explorer using PowerShell:

Disable-WindowsOptionalFeature -FeatureName Internet-Explorer-Optional-amd64 –Online
