Logging On Automatically

Some users don't like having to log on to Windows. When they restart the computer, they want it to boot all the way to the desktop without stopping at the Log On To Windows dialog box along the way. Before I tell you that this is possible (oops), let me add that you should never skip the logon process if your computer is connected to a business network. Obvious security concerns are present when you allow anyone with access to your computer to have full access to all of its contents and the network.

Preventing Messenger from Running (registry trick)

Believe it or not, some people don't like Windows Messenger, and they tire of the program's constant nagging to sign up for a Passport. Windows doesn't provide a user interface to remove Windows Messenger permanently. But you can prevent it from running. In Windows Messenger, click Tools, Options. On the Preferences tab of the Options dialog box, clear the Run This Program When Windows Starts check box. The problem with this setting is that the program still runs when other programs start. Clearing this check box removes the command that starts Windows Messenger from the key HKCU\Software\Microsoft\Windows\CurrentVersion\Run.

The most fail-proof solution is to set the policy that prevents Windows Messenger from ever running. You can set this policy using Group Policy editor to edit the local Group Policy Object.  You can also set the policy directly. To do that, create the REG_DWORD value PreventRun in HKLM\ SOFTWARE\Policies\Microsoft\Messenger\Client, and set it to 0x01. This setting affects all users who log on to the computer. When they try to run Windows Messenger, they don't see an error message: it just doesn't run.

Clearing History Lists using registry

So that you can quickly open documents and programs that you use frequently, Windows keeps history lists. These are MRU or “most recently used” lists. Table 4-7 shows you where in the registry the operating system stores these lists. Clear these lists by removing the keys associated with them. After removing the RecentDocs key, make sure to delete the contents of %UserProfile%\Recent, too.

The history list in Windows Search Assistant deserves a bit more attention. The key ACMru contains a variety of subkeys associated with the types of things for which you've searched. For example, if you search for files and folders, you'll see the subkey 5603, which contains a list of the different search strings. If you search the Internet using Search Assistant, you'll see the subkey 5001. You can remove each subkey individually to clear a specific type of query's history list, or you can remove the key ACMru to clear all of Search Assistant's history lists. Table 4-7 contains a list of the subkeys that 've found in ACMru.
