No Windows Steady State In Win7 ... but Guest Works

Paul Thurrott's SuperSite for Windows: Windows 7 Feature Focus: Guest Mode
Configuring Guest Mode

From a user experience perspective, Guest Mode is almost completely hidden in Windows 7. You can't access it from Start Menu Search (Go ahead, try. I dare you!), nor can you search for it from within Control Panel. It's like it's not there at all.

But it is. To find Guest Mode, open Control Panel, User Accounts and Family Safety, and then User Accounts. (Shortcut: Open the Start Menu and click your logon picture in the top right.) Then, click on Manage another account. From the list shown there, select the account for which you'd like to add Guest Mode. Or, if you don't have an account for this purpose, create one first.

Comments: If you have a motel lobby (library, mean kids, etc.) and used Steady State on XP then you will have to set up a Guest Account in lieu of Steady State in Windows 7, because Microsoft ain't given you no stinkin' Steady State for Win7. Mr. Thurrott explains how to do it.
