Leveraging System Context in Windows
Context Switches.; 2 minutes to read; In this article. The scheduler maintains a queue of executable threads for each priority level. These are known as ready threads. When a processor becomes available, the system performs a context switch. The steps in a context switch are: Save the context of the thread that just finished executing. We don't have any change log information yet for version 6.2.0.3 of X-Proxy. Sometimes publishers take a little while to make this information available, so please check back in a few days to see if it has been updated.

The method to switch between open apps in Task View replaced 'Windows Flip 3D' from Windows 7, and 'Switcher' in Windows 8. 1 Do step 2, step 3, or step 4 below for how you would like to open Task View.
I’d like to take things away from App-V for this blog if possible. Give the site a little more variety. I have been working with App-v mainly, however, I have also obviously been involved with MSI packaging and OS migration. With Windows 7, some features have been deprecated and as an IT professional, learning the little nuances in the new platform is part of the challenge and fun!
One of the first walls I ran into, with Windows 7, was met when I was working on a project that required me to perform my test install in system context. The reason why I wanted to do this was to mimic the install in the context it would be deployed in. Previously, when testing on XP, I would have used the ‘At interactive’ method to do this, but this is no more. A colleague of mine actually told me about this nice little tool for launching the command window in System context on Win7. I shall dispense this advice now(Crappy Sunscreen song reference, sorry)
How To Test an application install in the system context mode to mimic Deployment tools
You can open up an entry point in System context by following the below four steps.
Step 1: Run Command Window as Administrator
Step 2: Use psexec.exe
You will need to use the SysInternals Tool ‘psexec.exe’. These tools are a free set of troubleshooting and development tools that can be found on the Microsoft Technet site at the following location: – https://technet.microsoft.com/en-us/sysinternals/default.aspx The Sysinternals tools get updated so you should ensure you have the latest set.
Run the command as seen below (NOTE: Location of your psexec.exe may differ in this case I have copied the psexec.exe to the desktop as illustrated below):
A new CMD window should appear:
Step 3: Verify Context
Close the original cmd window as seen in Figure 2 and check Task Manager (Task Manager can be launched by right-clicking the taskbar and choosing Task Manager)(Explain how you launch task manager) to ensure your command window is now running in System context:
Step 4: Perform Actions
Run your install or do whatever it is that you aim to do in the System Context. This should help you to mimic the customer’s deployment method by installing in the correct context.

AppContext
Remarks
The AppContext class enables library writers to provide a uniform opt-out mechanism for new functionality for their users. It establishes a loosely-coupled contract between components in order to communicate an opt-out request. This capability is typically important when a change is made to existing functionality. Conversely, there is already an implicit opt-in for new functionality.
AppContext for library developers
Libraries use the AppContext class to define and expose compatibility switches, while library users can set those switches to affect the library behavior. By default, libraries provide the new functionality, and they only alter it (that is, they provide the previous functionality) if the switch is set. This allows libraries to provide new behavior for an existing API while continuing to support callers who depend on the previous behavior.
Define the switch name
The most common way to allow consumers of your library to opt out of a change of behavior is to define a named switch. Its
value
element is a name/value pair that consists of the name of a switch and its Boolean value. By default, the switch is always implicitly false
, which provides the new behavior (and makes the new behavior opt-in by default). Setting the switch to true
enables it, which provides the legacy behavior. Explicitly setting the switch to false
also provides the new behavior.It's beneficial to use a consistent format for switch names, since they are a formal contract exposed by a library. The following are two obvious formats.
- Switch.namespace.switchname
- Switch.library.switchname
Once you define and document the switch, callers can use it by using the registry, by adding an <AppContextSwitchOverrides> element to their application configuration file, or by calling the AppContext.SetSwitch(String, Boolean) method programmatically. See the AppContext for library consumers section for more information about how callers use and set the value of AppContext configuration switches.
When the common language runtime runs an application, it automatically reads the registry's compatibility settings and loads the application configuration file in order to populate the application's AppContext instance. Because the AppContext instance is populated either programmatically by the caller or by the runtime, you do not have to take any action, such as calling the SetSwitch method, to configure the AppContext instance.
Check the setting
You can then check if a consumer has declared the value of the switch and act appropriately by calling the AppContext.TryGetSwitch method. The method returns
true
if the switchName
argument is found, and when the method returns, its isEnabled
argument indicates the value of the switch. Otherwise, the method returns false
.An example
The following example illustrates the use of the AppContext class to allow the customer to choose the original behavior of a library method. The following is version 1.0 of a library named
StringLibrary
. It defines a SubstringStartsAt
method that performs an ordinal comparison to determine the starting index of a substring within a larger string.The following example then uses the library to find the starting index of the substring 'archæ' in 'The archaeologist'. Because the method performs an ordinal comparison, the substring cannot be found.
Version 2 of the library, however, changes the
SubstringStartsAt
method to use culture-sensitive comparison.When the app is recompiled to run against the new version of the library, it now reports that the substring 'archæ' is found at index 4 in 'The archaeologist'.
This change can be prevented from breaking the applications that depend on the original behavior by defining an <AppContextSwitchOverrides> switch. In this case, the switch is named
StringLibrary.DoNotUseCultureSensitiveComparison
. Its default value, false
, indicates that the library should perform its version 2.0 culture-sensitive comparison. true
indicates that the library should perform its version 1.0 ordinal comparison. A slight modification of the previous code allows the library consumer to set the switch to determine the kind of comparison the method performs.If application can then use the following configuration file to restore the version 1.0 behavior.
When the application is run with the configuration file present, it produces the following output:
AppContext for library consumers
If you are the consumer of a library, the AppContext class allows you to take advantage of a library or library method's opt-out mechanism for new functionality. Individual methods of the class library that you are calling define particular switches that enable or disable a new behavior. The value of the switch is a Boolean. If it is
false
, which is typically the default value, the new behavior is enabled; if it is true
, the new behavior is disabled, and the member behaves as it did previously.You can set the value of a switch in one of four ways:
- By calling the AppContext.SetSwitch(String, Boolean) method in your code. The
switchName
argument defines the switch name, and theisEnabled
property defines the value of the switch. Because AppContext is a static class, it is available on a per-application domain basis.Calling the AppContext.SetSwitch(String, Boolean) has application scope; that is, it affects only the application. - By adding an
<AppContextSwitchOverrides>
element to the <runtime> section of your app.config file. Vmware fusion 8 5 3 4696910 download free. The switch has a single attribute,value
, whose value is a string that represents a key/value pair containing both the switch name and its value.To define multiple switches, separate each switch's key/value pair in the <AppContextSwitchOverrides> element'svalue
attribute with a semicolon. In that case, the<AppContextSwitchOverrides>
element has the following format:Using the<AppContextSwitchOverrides>
element to define a configuration setting has application scope; that is, it affects only the application.NoteFor information on the switches defined by the .NET Framework, see the <AppContextSwitchOverrides> element. - By adding an entry to the registry. Add a new string value to the HKLMSOFTWAREMicrosoft.NETFrameworkAppContext subkey. Set the name of the entry to the name of the switch. Set its value to one of the following options:
True
,true
,False
, orfalse
. If the runtime encounters any other value, it ignores the switch.On a 64-bit operating system, you must also add the same entry to the HKLMSOFTWAREWow6432NodeMicrosoft.NETFrameworkAppContext subkey.Using the registry to define an AppContext switch has machine scope; that is, it affects every application running on the machine. - For ASP.NET applications, you add an <Add> element to the <appSettings> section of the web.config file. For example:
If you set the same switch in more than one way, the order of precedence for determining which setting overrides the others is:

- The programmatic setting.
- The setting in the app config file or the web.config file.
- The registry setting.
The following is a simple application that passes a file URI to the Path.GetDirectoryName method. When run under the .NET Framework 4.6, it throws an ArgumentException because
file://
is no longer a valid part of a file path.Contexts 3 6 2 – Fast Window Switcher Installers
To restore the method's previous behavior and prevent the exception, you can add the
Switch.System.IO.UseLegacyPathHandling
