How Do I Search The Registry For A Value In PowerShell

One of the easiest ways to find registry keys and values is using the Get-ChildItem cmdlet. This uses PowerShell to get a registry value and more by enumerating items in PowerShell drives. In this case, that PowerShell drive is the HKLM drive found by running Get-PSDrive.
As an alternative, you can also specify the registry item path to get the same output only slightly faster by using .NET. The below command is using the .NET Registry Class in PowerShell to get a registry value:
This where construction isn't bad for searching both property names and values (and the key name is a value). (Watch out for Netbeans. It creates an invalid registry dword key that causes an exception in get-itemproperty.)
I am trying to grab the "UninstallString" for a Registry key, however the Uninstall string contains a long path to the cached uninstaller. Basically what I want to do is search the registry for a keyword, then grab the value data and set it as a variable to call later.
Part of the problem is this program creates another registry key under that Uninstall Path, that also contains the name of the program I am trying to search "$NuanceAudio", that alternate key has an uninstall string, but it doesn't actually work. It's the Key that contains the QuietUninstallString that actually uninstalls the program correctly.
Because registry keys are items on PowerShell drives, working with them is very similar to workingwith files and folders. One critical difference is that every item on a registry-based PowerShelldrive is a container, just like a folder on a file system drive. However, registry entries and theirassociated values are properties of the items, not distinct items.
What I am trying to accomplish it to search through each key of the registry, and also each value for each key. If the key or the value contain anything relating to cisco anyconnect then I want to delete the value, and also delete the key.
PowerShell allows you to access the registry of a remote computer. You can connect to a remote computer either using WinRM (Invoke-Command or Enter-PSSession). To get the value of a registry parameter from a remote computer:
Following on from the last section, the command in that section returned all values in the specified registry path. However, you can also use PowerShell to read registry value but return a specific value.
Finally, for this sub-section, you can use PowerShell to read registry value and save the value in a variable. For example, we can save the registry data in the last command in a variable called $RegData.
Then, to display the type of registry value (in this instance, REG_BINARY), call the GetValueKind Method in the original command saved in the $key variable. Then, use CaptionFont (saved in the $name) as the value in the Method.
The IF statement compares the current value in the registry key with 1. Then, if it is not equal to 1, it uses the Set-ItemProperty command to update the value to what you specify in the Value parameter.
If you want to see the value of a specific registry key value, use Get-ItemPropertyValue, specifying both the registry key (as a default argument, or with the -Path parameter), as well as the registry value name with the -Name parameter (again in this example I use the relative location . and the fully-qualified location to show how both can be used):
Unfortunately, not all drive providers support the same parameters. While searching for a file on the file system with Get-ChildItem is pretty straightforward (Get-ChildItem -Path C:\ -Name mimikatz.exe -Recurse will find all files with the name mimikatz.exe, for example), this won't work with registry keys:
If you want to find a registry value by name, we can use a similar Get-ChildItem command, filtering by the Property property instead of Name. For example, to search for a registry value name called LastLogonTime-Machine, use the following command:
