On your C:/ partition exists a folder from which the system initiate programs automatically at start up. This folder is named Startup, obviously, isn’t? What you have to do is to put in that folder the shortcuts from the programs you want to start when windows boot.

The way to find out Startup folder on my computer is:

C:\Documents and Settings\John Smith\Start Menu\Programs\Startup\

It should be something similar on your computer. Open Windows explorer or Total commander (I use it for a while) and follow the steps.
Once you found it, create the shortcuts for the programs you want to run when you open the computer. To create a shortcut, right click into that Startup window / New / shortcut and locate the .exe file you want to create the shortcut. Add as many shortcuts you want.
To remove a program from running at the computer startup follow the same path and delete the shortcuts you don’t want or press Windows button + R, write msconfig, go to startup tab and deselect the programs you don’t want to run when computer starts.

Warning: in Startup folder is a file: desktop.ini
Be sure you do not delete that one! Even it’s there just to customize this folder, in my opinion is better if you let it there.

Running a trial version of a software without expiring can be possible using a small piece of program named RunAsdate which 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. This program is working only in 32bit environment. The best part: it’s FREE!

Let’s get started. Give it a search in your search engine for: RunAsdate, download it and run it.

Open the application you want to hack, chose a date and time you want the application to run all the time you open it and create a shortcut desktop which you will use it to open that program from now.
