# Maintaining App-V 5.1


After you have completed all the necessary planning, and then deployment of App-V 5.1, you can use the following information to maintain the App-V 5.1 infrastructure.

The App-V 5.1 server connects to the App-V 5.1 database. Therefore you can install the management component to any computer on the network and then connect it to the App-V 5.1 database.

## <a href="" id="determine-if-an-app-v-5-1-application-is-running-virtualized-"></a>Determine if an App-V 5.1 Application is Running Virtualized


Independent software vendors (ISV) who want to determine if an application is running virtualized with App-V 5.1 or above, should open a named object called **AppVVirtual-&lt;PID&gt;** in the default namespace. For example, Windows API **GetCurrentProcessId()** can be used to obtain the current process's ID, for example 4052, and then if a named Event object called **AppVVirtual-4052** can be successfully opened using **OpenEvent()** in the default namespace for read access, then the application is virtual. If the **OpenEvent()** call fails, the application is not virtual.

Additionally, ISV’s who want to explicitly virtualize or not virtualize calls on specific API’s with App-V 5.1 and above, can use the **VirtualizeCurrentThread()** and **CurrentThreadIsVirtualized()** functions implemented in the AppEntSubsystems32.dll module. These provide a way of hinting at a downstream component that the call should or should not be virtualized.
