In this question I saw that you can use command key to store credentials and then just run a command like mstsc /v:servername to connect to it without typing anything.
Additionally, you can delete it using the /delete switch of cmdkey...would I be able to make sure when I log out for the day the credentials are gone?
Is this at all safe?  Or is it more like ssh-agent where the key is held in memory for a specified period of time?  Or is this stored on disk and I should use something like cipher to encrypt the folder before use?
