Normally applications should register themselves for all protocols they understand. This works great for http:, https: (webbrowsers) and mailto: (MUAs). You can even configure which program should "own" a protocol if you have more than one. Some programs don't bother registering for whatever reason. E.g., the makers of PuTTY refuse to register PuTTY as ssh: handler because there is no proper standard for ssh: URLs, yet. If you're like me and can't wait for that standard to be set in stone, then you could simply assume ssh: links will look a lot like telnet: links and use UrlConf to register PuTTY as ssh: protocol handler. UrlConf is a program to configure URL protocol handlers.

The User Profile Hive Cleanup service helps to ensure user sessions are completely terminated when a user logs off. System processes and applications occasionally maintain connections to registry keys in the user profile after a user logs off. In those cases the user session is prevented from completely ending. This can result in problems when using Roaming User Profiles in a server environment or when using locked profiles as implemented through the Shared Computer Toolkit for Windows XP. On Windows 2000 you can benefit from this service if the application event log shows event id 1000 where the message text indicates that the profile is not unloading and that the error is "Access is denied". On Windows XP and Windows Server 2003 either event ids 1517 and 1524 indicate the same profile unload problem. To accomplish this the service monitors for logged off users that still have registry hives loaded. When that happens the service determines which application have handles opened to the hives and releases them. It logs the application name and what registry keys were left open. After this the system finishes unloading the profile .....(free).....

MJ Registry Watcher is a simple registry, file and directory hooker/poller, that safeguards the most important startup files, registry keys and values, and other more exotic registry locations commonly attacked by trojans. It has very low resource usage, and is set to poll every 30 seconds by default, although you can adjust this to anywhere between 0 and 9999. A configuration file stores all your settings for future use. MJRW not only polls the system, but it also hooks it, so that most changes to keys, files and directories are reported instantaneously. Key deletions are still caught by the polling loop though, since they cannot be hooked. Exactly which keys and files are protected can be completely configured by the user, although the sets I supply with MJRW will cover most standard PCs
