[PowerShell每日技巧]使用不同的用户打开PowerShell(20131118)

DAIC

Once you pin PowerShell to your taskbar, you can always right-click the pinned PowerShell icon to open a jump list and launch PowerShell or the ISE editor with full Administrator privileges.

You can, however, also hold SHIFT and right-click the PowerShell icon inside the jump list. This will open another context menu, and here you can choose to run PowerShell with completely alternate credentials.

There is no such option for the ISE editor, but once you launched PowerShell with alternate credentials, you can simply enter the command "ise" to run the ISE editor under the same account.
