WSE RemoteApp allows you to hide certain items (such as all of the local server drives [C:, D:, etc.], all of the Network drives, etc.) from the navigation pane of This PC / File Explorer (or Computer / Explorer) in your user’s RemoteApp sessions as follows:

1. Open the server Dashboard application and go to the “WSE RemoteApp” page.
2. Click on the “Server Access Settings” task.
3. Under the “Access Restrictions” section, check the checkboxes for the server items that you want to hide/block user access to.
4. Click on the “Save” button to save your changes.

Note that your users “may” need to actually sign out (or log off) of their current RemoteApp session (and not just disconnect it) in order for the changes to take place. Also, please make note of the informational tips that appear whenever you hover your mouse over the little thought bubble icons seeing as enabling some of the settings may affect compatibility with some services, applications, etc.

That “should” cover most of the common items. However, if you need to hide other select items (such as individual CD drives, Network drives, etc.), then you’ll most likely need to do some research on the Internet to see if it can be done (using Local Group Policy or Registry settings, etc.). I try to cover the more common ones, but it’s just not possible for me to do them all (especially those that vary from server to server).
