This question is related to a similar one on here.
I have just upgraded a Windows 8.1 tablet to Windows 10 and then connected it to my Windows Home Server 2011 and installed the Connector. I ran a manual backup and it failed with VSS errors on the client.
The linked question was cleared by install hotfix 2781272 which is supposed to correct a problem whereby the connector cannot backup a UEFI formatted disk. I tried to install the hotfix but got an error saying "The update is not suitable for your computer".
