Invoke-Command removing temp files

For some reason c:\windows\temp seems to be filling up with Windows Updates on a lot of our servers. Here is a quick Invoke-Command solution.

Invoke-Command -ComputerName $computername -ScriptBlock {Remove-Item c:\windows\temp\* -Force -Recurse}
Invoke-Command -ComputerName $computername -ScriptBlock {Get-PSDrive c}

Putting it all together

We now know how to convert a SecureString to an encrypted standard string. We can take any method we like to get a SecureString, convert it to a standard string and then save it to a file. Here is an example of each:

Exporting SecureString from Plain text

"P@ssword1" | ConvertTo-SecureString -AsPlainText -Force | ConvertFrom-SecureString | Out-File "C:\Temp 2\Password.txt"

Exporting SecureString from Get-Credential

(Get-Credential).Password | ConvertFrom-SecureString | Out-File "C:\Temp 2\Password.txt"

Exporting SecureString from Read-Host

Read-Host "Enter Password" -AsSecureString | ConvertFrom-SecureString | Out-File "C:\Temp 2\Password.txt"

Any one of these examples should provide you with a Password.txt file that has an encrypted standard string the represents the password.

When you need to use this encrypted password, you simply reverse the process by importing the data from your file and use ConvertTo-SecureString. If all you need is a SecureString, you can stop there. You could even take it a step further and create a PSCredential object.
Creating SecureString object

$pass = Get-Content "C:\Temp 2\Password.txt" | ConvertTo-SecureString

Creating PSCredential object

$User = "MyUserName" $File = "C:\Temp 2\Password.txt" $MyCredential=New-Object -TypeName System.Management.Automation.PSCredential ` -ArgumentList $User, (Get-Content $File | ConvertTo-SecureString)
