Install RSAT on Windows 10 1809

Recently updated to Windows 10, version 1809, removed the Remote Server Administration Tools (RSAT) that were previously installed.  This is common with such updates, however, this time around I was unable to reinstall the tools.  After much digging, I discovered that this is because Microsoft has made the RSAT tools a part of the “Features on Demand” in Windows 10.

Features on Demand (FODs) are Windows feature packages that can be added at any time.–capabilities

More info on Windows Features on Demand:

To install RSAT on Windows 10 version 1809, open an elevated Command or PowerShell and run the following DISM command:

DISM.exe /Online /add-capability /CapabilityName:Rsat.ActiveDirectory.DS-LDS.Tools~~~~ /CapabilityName:Rsat.BitLocker.Recovery.Tools~~~~ /CapabilityName:Rsat.CertificateServices.Tools~~~~ /CapabilityName:Rsat.DHCP.Tools~~~~ /CapabilityName:Rsat.Dns.Tools~~~~ /CapabilityName:Rsat.FailoverCluster.Management.Tools~~~~ /CapabilityName:Rsat.FileServices.Tools~~~~ /CapabilityName:Rsat.GroupPolicy.Management.Tools~~~~ /CapabilityName:Rsat.IPAM.Client.Tools~~~~ /CapabilityName:Rsat.LLDP.Tools~~~~ /CapabilityName:Rsat.NetworkController.Tools~~~~ /CapabilityName:Rsat.NetworkLoadBalancing.Tools~~~~ /CapabilityName:Rsat.RemoteAccess.Management.Tools~~~~ /CapabilityName:Rsat.RemoteDesktop.Services.Tools~~~~ /CapabilityName:Rsat.ServerManager.Tools~~~~ /CapabilityName:Rsat.Shielded.VM.Tools~~~~ /CapabilityName:Rsat.StorageReplica.Tools~~~~ /CapabilityName:Rsat.VolumeActivation.Tools~~~~ /CapabilityName:Rsat.WSUS.Tools~~~~ /CapabilityName:Rsat.StorageMigrationService.Management.Tools~~~~ /CapabilityName:Rsat.SystemInsights.Management.Tools~~~~


Once the install has completed you will notice the tools installed again under ‘Windows Administrative Tools’.

Veeam, vSphere 6.5, Restore job failed Error: A specified parameter was not correct: spec.vmProfile

Just a tech short on how to get past the following error: Restore job failed Error: A specified parameter was not correct: spec.vmProfile. This was encountered when testing backups via the Veeam console

This error could also be seen in vCenter


After some digging around I was able to get a better understanding of why it was occurring. Each time this failure would occur I would see a message “Failed to set story profile VM Encryption Policy …

But I am not using encryption policies!

This is new in vSphere 6.5 and allows for the encryption of storage where the VM would reside.
To work around this I needed to browse my datastore tree for the intended datastore rather than searching by name; What I had been previously doing.

You may see this as ‘Default policy’ container.  Select the datastore and continue as normal and you should have a successful restore.

Best of luck to you.
