Creating a Custom OS Template (Windows)
An admin in your organisation can craft a custom OS template for spinning up remote desktops. It's also a great way to activate your own license on the operating system.
These steps are crucial for building a successful image. Proceed with caution.
Important:
About Disk Partition
1. Your template should have only one disk partition, or two: an EFI/Boot partition and a combined system and data partition.
2. LVM partitions aren't supported—avoid using them.
3. An incorrect partition layout will cause the auto-resize and machine naming features to malfunction.

8. Enable Shared-drive
â Shared-drive lets you share files across cloud desktops during a training course, or between your local PC and the cloud desktop. It relies on WebDAV technology. Before you can use it, you’ll need to map the network drive. Check the screenshot below for guidance.
