The exceptions to this are services that need to interact with the console user, so these load into Winsta0 instead. All pages mapped to a specific user use the same memory pages, but each user has their own session space mapped in virtual memory.
Session space is divided into four different areas:. As mentioned above, a desktop is an object under which a logical display surface loads. This contains windows, menus and hooks. Session 0 is the base session where services run and is typically also the console session. In Windows Vista this has been changed to exclusively run services, and the console session is typically Session 1. The diagrams below show the relationships between sessions, windows stations, desktops and services in Windows Vista as compared to earlier operating systems this is from our earlier post on Session 0 Application Compatibility Issues.
So now let's dig a little deeper using an example. In the diagram below, we are looking at Session 0 with a user logged in named Bob. As you can see, Winsta0 contains both processes from the user console session as well as any service that is marked as Interactive.
In this case, that includes Winlogon. In this case I have shown Services. As you can see by the connecting bars, it is possible for processes from different virtual sessions to load into a single windows station. The SQL process loads under its own windows station and credentials, so it is not included in either of the other windows stations.
A single desktop object will have a single desktop heap set aside for it. This heap stores various user interface objects, such as the windows, menus and hooks. When an application needs to draw a user interface object, it calls User As I am sure you can guess, each of these interface elements requires resources out of desktop heap. If the desktop heap becomes depleted, you will get symptoms such as a corrupt display or other anomalies. Also, if the Session View Space becomes depleted, it will not be able to create more desktop heaps.
Either of these of course is very bad. The information in this document was created from the devices in a specific lab environment.

I do not need any comment about whether SFC helps solve a problem or not. In reply to jsobry's post on February 26, Try this for Windows 7: 1.
Left click the Start button at the lower left hand side of the screen. Type "cmd" without the quotes in the Search Programs and Files box 3. The pop-up window should show cmd under Programs.
