Hello, I have a VM with a .vhd file however, when I connet to the VM (by RDP) and make some changes (create a directory and add a small file with notepad) the .VHD file stays unchanged. The 'Date modified' of the .VHD stays at the starttime of the VM. 1/How can we force an update of het VM while the VM is running? 2/Where aree the temporary changes kept? Hypervisor: Microsoft Hyper-V server 2008R2 (free download version) regards, Maxim
