1. Potentially reduce per-desktop infrastructure resource requirements, optimize performance, and eliminate specific known issues related to using the target OS as a virtual desktop.
2. Hibernate, disk defragmentation, automatic updates, Windows error reporting, and Windows System Restore.
3. Disable native application update features, perform any required software activation or activation workarounds, and optimize application settings
4. Causes unneeded disk IO when writing Windows RAM contents to disk, and leads to slower login times when reading RAM contents back into memory when the user logs in again.
5. Linked clones are typically updated by updating the master image, then recomposing users to that new image. If you applied an update directly to a link clone, the space it requires would increase significantly since its configuration would no longer match the virtual desktop master image.

6. Defragmentation would increase space utilization since any moved blocks would be written to the link clone disks.
7. Since Windows does not have to create a new profile from scratch, user login times are typically reduced as fewer infrastructure resources are required to process the users' first logins.
