I have a batch file that i have added to the right click context menu of my recycle bin. it calls several programs on my computer. whenever i run it in vista the user account control pops up for every seperate program my batch file runs. I can prevent this by running the program as administrator. the context menu uses a command line to call the batch file. I've tried using the runas command but then i have to enter the username and/or password for the admin account. i want to be able to use this on someone elses computer. so i want to be able to run it as administrator without needing to know the user name or password essentially i need a command line command that will run a batch file as administrator (or with admin rites) without the need to know user name or password
