Do not use temporary folders per session

This policy setting allows you to prevent Remote Desktop Services from creating session-specific temporary folders. You can use this policy setting to disable the creation of separate temporary folders on a remote computer for each session. By default, Remote Desktop Services creates a separate temporary folder for each active session that a user maintains on a remote computer. These temporary folders are created on the remote computer in a Temp folder under the user's profile folder and are named with the sessionid. If you enable this policy setting, per-session temporary folders are not created. Instead, a user's temporary files for all sessions on the remote computer are stored in a common Temp folder under the user's profile folder on the remote computer. If you disable this policy setting, per-session temporary folders are always created, even if the server administrator specifies otherwise. If you do not configure this policy setting, per-session temporary folders are created unless the server administrator specifies otherwise.
