If we want to install a specific update, we can use the updateID property from the Update Identity object. The results are seen here:. We then use this variable when we call the Search method from the Searcher object. After the update has been found, it is added to the UpdateCollection by using the Add method. The return code from adding the update to the collection is discarded by piping it to the Out-Null cmdlet.
The updateID f1b1abbb1c-9fbdeedb00cc9d is the Windows Search 4. This section of the code is seen here:. We now need to download the updates. To do this, we use the CreateUpdateDownloader method from the Session object. The updates from the UpdateCollection are assigned to the Updates property of the Downloader , and the Download method is called.
This section of the script is seen here:. Now it is time to install the update. To do this, we need to first create an instance of the Installer object. We then call the Install method as seen here:. A ResultCode of 2 means the operation succeeded. The first set of results is returned by the Download operation, and the second set of results is returned by the Install operation.
Table 1 documents the result codes. If a problem occurs during the installation or download, the Installation Results object IInstallationResult interface can at times provide information that is useful in troubleshooting the script.
An example of such an error can be seen here:. To interpret the results, we need to first convert the value to hexadecimal. To do this, we can use the Calculator Calc. Well, GB, I hope this will help you get back into the habit of checking your event logs.

You are inside a Windows PowerShell console and want to start the script in a new Windows PowerShell console, change the console title to be the name of your computer, and pass an argument to the newly started script. The command seen here is one logical command, meaning it can be cut and pasted directly into the Windows PowerShell console as is, or you could type it as one long command and let it wrap. The semicolon is the new command character, and it is used to introduce a new logical command line.
You would use it when typing in the Windows PowerShell console. The Windows PowerShell command is seen here:. The above command starts a new instance of PowerShell. WindowTitle exposes the title property of the Windows PowerShell console. When you cut and paste the command above, you see double arrows at the beginning of each line.
