A normal problem that we face is that we can't buy all the softwares that we would like to use as they cost too much. So,we use their trial versions that expire after a fixed period of time.But what do you do when they expire -format your system to use them again or buy it eventually??Well here is a solution to your problem that makes you use your trial versions indefinitely without formatting your system.Here is a list of some softwares that uninstall the expired softwares completely without leaving any trace so that you can install the trial version again for reuse.
Altiris Software Virtualization Solution
Altiris
Software Virtualization Solution (SVS) is a new way to use software. By placing applications and data into managed units called Virtual Software Packages (VSP's), SVS allows you to instantly activate, deactivate, or reset applications, to completely avoid conflicts between applications, and to remove them cleanly without altering the base Windows installation.
Once installed on a system, SVS runs continually. If you install a program under it, SVS grabs all changes to the Registry and file system (including added and deleted files) that the installer makes and puts them in what Altiris calls a layer. Thereafter, the virtualization software directs file and Registry calls to the layer or to the base system as appropriate. The SVS-installed app looks perfectly normal, but disappears without a trace when you deactivate the layer. You can turn the app on and off like a light switch.

Sandboxie
When you run a program on your computer, data flows from the hard disk to the program via read operations. The data is then processed and displayed, and finally flows back from the progam to the hard disk via write operations. Sandboxie changes the rules such that write operations do not make it back to your hard disk.
- Intercept changes to both your files and registry settings, making it virtually impossible for any software to reach outside the sandbox.
- Traps cached browser items into the sandbox as a by-product of normal operation, so when you throw away the sandbox, all the history records and other side-effects of your browsing disappear as well.

Total Uninstall
Total Uninstall helps monitor any changes made to your system during the installation of a new application.
It allows you to perform a complete uninstall
without having to rely on the supplied Add/Remove program which can leave files or changes behind.Total Uninstall creates a snapshot of your system prior to installing a new application. It then takes an additional snapshot after the installation has completed. It then compares the two snapshots and displays all changes in a graphical tree view, marking all registry values and/or files that have been added, changed or deleted. Total Uninstall saves these changes and if you decide to uninstall the application, it will reverse the changes to the previous state. Any other computer activity during this period that makes changes to the file system and/or registry will also be monitored.
