@Nitin011 You can resize the OS disk on the Cloud PC. Provided you have the necessary license available within our admin portal. Note you cannot downsize the OS disk post increasing the size. As far as partition is concern there is no official way to create partitions but you can leverage the known partition tools etc. You will not get any support from Microsoft on that. If you feel it will be a feature required by many submit a feature request here - https://feedbackportal.microsoft.com/feedback/forum/6ab53114-95ab-ec11-9840-000d3a1c7d74
