Everytime you install a software loads of dll and other files get installed into your windows directory and leaves lot of junk after uninstallation. We need a solution that will keep our windows installation clean after several installation and uninstallation. Altiris Software Virtualization Solution (SVS) does precisely that.
With Altiris SVS, you can install any program to a transparent layer that snags all attempts that the program makes to write to your system, instead saving them inside of the layer. That means no extra .dll's and no permanent registry changes - SVS takes care of all of that. A big relief from malfunctioning windows due to buggy software and you can even use your favourite trial software for eternity....

Another software that might interest you is Sandboxie. This s/w allows you to run programs inside a "sandbox" thereby protecting your windows and registry from any changes. However this is not permanent and once you exit from Sandboxie, the running program and all the changes will be gone. But helpful if you want to surf the web and remain free from spywares.
