We usually download trial versions of softwares and games.But we really get annoyed when these trial versions expire after a fixed period of time.we always wished to use them as full versions.Now I have got a solution to this problem that makes us use trial versions indefinitely forever.
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.
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.
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.
RunAsDate intercepts the kernel API calls that returns the current date and time (GetSystemTime, GetLocalTime, GetSystemTimeAsFileTime), and replaces the current date/time with the date/time that you specify. It works with Windows 2000, XP, 2003, Vista and 7. It works with 32 bit and 64 bit versions.
