Software Trial Period Principles and Test Methods 10

Hello! Trial period software is officially released software! You can't see the internal process!

So you can only be superficial functional testing! The principle of calculation can only be asked by the person who developed this software! If you can just reset the time and use it again, that's a bug for the software!

The software says it's only 10 days long! That is to say: for example:

I'm January 11, 2011 at 9:17:01! Then on January 21, 2011 at 9:17:02, you will be asked to pay the fee. . . The specific accuracy is seconds, minutes or hours, and you will know by testing it yourself.

Maybe the software has a built-in timekeeping tool.

The timer starts when you start.

It was the day when his timer was up.

expired will be displayed.

This software has written time into the registry or somewhere you don't know it. From the moment you install it, it has nothing to do with system time.

In fact, there are many store cash register software on the market, such as: Yishi cash register software, which is a free cash register software. Why bother to toss a software that requires a fee, even if it is cracked, there is still no good service.

In fact, for a single store, these free cash register software are enough for you to use, you might as well try it, after all, you will know the good or bad only when you use it.

There should be an authorization timing file, add 1 day before a day has passed, and how many days have passed for each start test.

This way you simply change the system time is invalid!

You try to change the time of the bios. The software may be reading the BIOS at the time.

Nowadays, many software have their own timing systems, and the era of computers alone is gradually becoming obsolete!

The trial period of the software balance slag test is not very sad.

Because you have entered the probation period, it means that you have passed the interview of the company, this time there is only one process left this year, the company will think that you are suitable for this position, so it is generally easy to pass, and it takes a lot of time and energy for the company to recruit a person, and it will generally not card you, unless you really can't adapt to the job.

The reason why the software with a trial period cannot be used after the trial period is because the software modifies the registry during installation, and the number and time of use when you use it are recorded in the registry, and it cannot be used after the specified number is exceeded. When you uninstall and reinstall, the original registry is still there, so it still doesn't work.

There are two ways to solve this:

Method 1: Find a cracked version or use a keygen or crack patch as much as possible;

Method 2: Use the perfect uninstall software to help you monitor the registry before installing the software before installing the software. After the trial period, I still use Perfect to uninstall the software. Doing so will remove the entries from the registry.

Then you can enable Perfect Uninstall the software, install the software, and you can use it again.
