We then check to see if the registry key exists. If it does, we create a variable named $swv and set it equal to $null. We then print out another debug message: Copy "Stop" { Write-Debug "Stopping Timer" If(Test-Path -path $path) { $swv = $null Write-Debug "$path was ...
A better approach is to test the registry key path first, creating it if needed, then setting the value entry, like this: Copy # Set variables to indicate value and key to set$RegistryPath='HKCU:\Software\CommunityBlog\Scripts'$Name='Version'$Value='42'# Create the key if it d...
When usingNew-Itemwith the-Forceswitch to create registry keys, the command will behave the same as when overwriting a file. If the registry key already exists, the key and all properties and values will be overwritten with an empty registry key. ...

Adding the key and value This script shows how you can use the resource with thedsc resourcecommands to ensure theMyKeyregistry key exists with theMyValuevalue set to binary data0x00. With_ensureset toPresent, the resource adds the registry key and value if they don't exist. ...
This behavior can work as long as thehomerunspace still exists. However, you may not get the desired result if the script is dependent on external variables that are only present in the caller's runspace and not thehomerunspace. Non-terminating errors are written to the cmdlet error stream ...
If the resource doesn’t exists and the ensure property is set to Absent, then it should do nothing. Now it’s time to implement these three functions related to the TrustedHosts custom resource. Open Windows PowerShell ISE, implement these three functions and save it...
Basically, data is only available to the current user or the assembly in which the code exists (it can also be isolated by domain).When using IsolatedStorage in these examples, I will be saving a key/value pair as strings. IsolatedStorage can store any type of data you need, but I'm ...
