    I recently purchased and installed some software after trying out the 30 day trial software. The thing is, i tried it a couple of months ago and when i was done I completely reinstalled it and I have cleaned and defragged the registry since then, but when I downloaded it again and reinstalled it it immediately told me the trial limit had expired and to put in my activation code, which I did.

    I was thinking about it and was wondering how the software companies do that, do they use some sort of rootkit or brand your computer in some way? if I try out alot of different trial software can it start to impact performance?:wtf:

    There are either still keys in the registry, and this is the most likely. Or some file remains.

    No. just probably a random generated registry key.

    Thus unknown to the user unless they can backup the registry, install it, un-install it, then compare registry dumps.

    so what would be the best way to remove it? a regcleaner didn't seem to work.

    search the registry for the company name and delete those keys if you feel like that is safe.



    I have done it but woudn't reccomend it.

    Regmon, or FileMon from System Internals can help here, by showing you WHERE on disk &/or the registry the installation is writing data to (files on disk, or registry hives (also files too)).

    The COMBINED utility of theirs, new one (consolidates the functions of RegMon & FileMon into 1 package basically), ProcMon will do also... probably the best choice.

    Get these tools here (Microsoft site now):

    http://www.microsoft.com/technet/sysinternals/default.mspx

    :)

    * Should help you 'circumvent' this, via spying on the apps @ INSTALLATION, & WHILE RUNNING THEM AS WELL (especially @ startup is where you want to pay attention to them), as these tools basically, DO, tracing file operations of this application's read/write I-O!

    APK

    P.S.=> If the key for the reinstallation NOT being fooled by the entries the program makes @ install & tracing it as you first will/should do here?

    Then, You may have to run the app for a bit, & see where it's READING from @ startup mostly & pursue those file/registry entries this app's using to count times used/how long used, etc. et al... that's most likely the KEY here... apk
