BleepingComputer.com: A good registry cleaner?

I want to remove all registry keys of a program. Is there a good one? Actually I installed a trial version which I had to remove before its trial expired but now when I reinstalled it I get same message that" Trial expired"(actually its windows blinds). Eventhough I installed it today still it shows trial expired. Can anyone help me? Actually my main problem is this only that the trial version shows expiration before actual time.

Just my opinion, but if it were possible simply to uninstall and reinstall trials, no one would ever bother to buy programs.

I doubt if you could find all the keys in the registry by normal means, as some will be buried in an unrecognisable form.

The programs which purport to be able to find all the keys are more along the lines of hacking tools
and may contain malware/spyware etc. which could cause you problems.

Registry Cleaners will not help you either and they are NOT recommended in these forums.

You could try uninstalling with one of these.

REGSEEKER should clean up any UN-NEEDED keys (If you got rid of a program and are trying to clean the reg)

http://www.hoverdesk.net/freeware.htm I love this program! (1st time i ran it it removed over 850 keys!)

ALL THE GREEN ENTRIES IT FINDS ARE OK TO TELL IT TO DELETE (After the scan)

All RED entries may be needed (Regseeker cant determine it which is why they are RED (Use caution deleting those))

Well...IMO, if you must play in the registry, do it manually, using regedit...backup the registry before doing anything...then begin a search, using appropriate keywords (software name, developer, etc.) and you should get all entries.

Anything less than that is a very weak effort to get ALL the reg values related to a program.

FWIW:

Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons:

• Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.
  
  The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.
  
  
• Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.
  
  
• Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.
  
  
• Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.
  
  
• The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".

Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.
