asked on

uninstalling any software leaves roots in the registry...

Hello Experts,
I have noticed that any software when uninstalled leaces traces of its existence behind in the register as keys and values....

Why are not all of these erased with the uninstall process ?
Is it posible that they use these roots to know if the software was previously installed and many other things?

How can I get rid of those without going one by one?

And finally I found some legacy keys that simpy cannot be erased...
Please you support explaining these...
Best regards,

Use Revo Uninstaller to uninstall (use advanced scan option).

my job has to do with security among other functions.. is it posible that one of these left behing keys and data may be used to call a program on the internet or install an unauthorized program?

can any software developer store in the registry some info like credit card data or other sensitive data that can be used after uninstalling their software... I am thinking they can also leave another module silently maybe when installing and stays after uninstalling..

>>  Reputable software vendors do NOT do what you suggest  <<   i have not yet found any program, that removes all traces after an uninstall - but that's my opinion.
i also use Revo; and after the unstall was done, you can remove keys with Regseeker:   http://www.hoverdesk.net/freeware.htm
rguillermo--I also use Revouninstaller.

However, even assuming there is some malicious bits to a software program, remember that you are no worse off after having uninstalled the program compared to the situation before uninstallation.
and even after revo - there are often traces left
i always wonder why they don't make a better install/uninstall system
I've requested that this question be deleted for the following reason:

Not enough information to confirm an answer.
You cannot remove all traces of software and that was stated accurately:

And the post by nobus  http://#a39728621

These are both good answers to the question.
