    Exploring the Registry (Vista Home Premium)

    Hello and greetings,
    When running "CCleaner"http://www.ccleaner.com/update/?v=2.13.720&l=1033 in the "cleanup registry" mode there is a "KEY that refuses to be deleted. (see attachment) When i find it using "regedit" and explore in HKEY_CLASSES_ROOT and try to delete manually i get "error while deleting key"
    Also the same when trying to do the same for some other "Keys". Question: is this normal (not being able to delete some items) or do i need another "unlocker" of some sort? Just trying to learn how this works, and not too worried about "messing up" as i have several "full images" at the ready! Regards

    Fred,

    You could try to Export the key to a file first and then Import it, IF it messes things up.

    I don't know of any protection placed in regedit that would prevent you from deleting it but I could be wrong here.

    You ARE logged in as Admin aren't you?

    Not only are you logged on as an Administrator (account), which I would assume you are, but also, are you opening (running) Regedit "as an Administrator"? In short, do you right-click on the "regedit" link and choose, "Run as administrator"? This elevation of privileges might resolve the problem. <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15>

    Bob,
    Hello again, sorry took so long to respond (can't log in during evening hours ?) I tried the "export / Import" route it would work and i could delete the "KEY" (new folder) , but it would only copy the "KEY" The original was still in place. Question: could this be that the "KEY" is used some where else? (some other function?) so you would have to find and delete that first? Also i have successfully deleted "leftovers" from my "Take back control of my PC program" that were in the other registry entries, without problem.

    Jeff,
    Hello again also! (Thanks guys!) At first i entered the registry through the right click command in "CCleaner" clicked on the "recalcitrant KEY entry" so did not have the opportunity to run as "Administrator" However i use "Winbubble" elevate without prompting" As per your suggestion, i tried using the administrator tools/system configuration / launch RegEdit. Right click run as administrator with the same results. Guess that i'll have to dig a little deeper into the registry to try and find out about the "CLSID" (Class ID) type entries. Regards

    Woody's Lounge is currently *very* slow between 23:00 and 01:00 UTC (Greenwich Mean Time), corresponding to between 6 PM and 8 PM EST. This is because the daily backup of the server is made during that time. I apologize for the inconvenience.

    You have me confused here. If you export a Key to another location, it will be a COPY of that key and have a .reg file extension. This is so you can just run the reg file and it will replace the key at whatever location it was found in.

    After you export it, then you should be able to delete that key directly from the reg .
    If there is a duplicate somewhere else in the reg, it should not prevent you from deleting it at that location.

    Am I reading you wrong?

    Bob,
    Hello and thank you for your reply. I have "exported" the KEY {76D0CB12-7604-4048-B83C-1005C7DDC503} to my documents, when i go back to the registry i still can not delete it. If i try to copy the whole path "HKEY_CLASSES_ROOT blah_blah " a error message prompts "cannot resolve path"? Well seeing how this is only my
    2nd attempt at this land of "OZ" (registry) i guess that i could have very well confused anyone including myself! sorry if i was unclear. Regards

    Don't try to mess around copying the entire reg ROOT, etc.

    Try to boot into Safe Mode and then use regedit to try to delete JUST the CLSID in question.
    There is another program called SuperShell that would work in XP but nor sure about Vista. I would be very careful using that one though!

    BTW, Do you know if this is causing a particular problem with you system or is just CCleaner that's telling you it found a problem?

    Another possibility.
    Some registry entries have an embedded null character in them which prevents deleting from the registry.

    There is a utility written by the Windows SysInternals guys that will scan for allow deletion of these entries.

    Check it at this SITE

    Bob,
    I will try the suggestions, and post back (if i still can boot my PC!) As the "witching hour" approaches (6:00pm est) i won't be able to log in. Thanks again,
    the"TechNet" site looks like this could be the answer..Also in answer to your question ... no problems (so far) with all my "deleting of bits of the "OS" Just CCleaner's not being able to get rid of some "leftovers" from my "great purge" of unwanted micro-squish programs! This latest foray of mine into the (Land of OZ) registry is both fun and scary and am learning how to "clean up" manually all the leftover bits. Glad i have Acronis on my 6! Regards. PS sorry about thelarge screen shot ,dont know how to make it smaller.

    There are many free utilities that let you resize images, for example:
    VSO Image Resizer (lets you resize a picture by right-clicking it in Explorer) and FastStone Photo Resizer.

    Re: Exploring the Registry (Vista Home Premium)

    Fred,

    Cleaning the Registry is one of those "taboo" discussion subjects and there is some merit to that reluctance to recommend Registry Cleaners since most individuals have no prior knowledge about the Registry (most won't take the time to learn either <img src=/S/RollEyes.gif border=0 alt=RollEyes width=19 height=19>). And thus making recommendations can lead to disastrous results; e.g., hosing the entire system. Yet, if someone is adamant about playing around in the Registry, for myself, I would rather recommend a "tried and true" Cleaner rather than have someone get duped into trying or worse yet buying one of the myriad useless and/or dangerous Registry Cleaners, so-called, which are out there.

    With that disclaimer out of the way, aside from CCleaner, there is only one Registry Cleaner that I have come to trust (and that's not 100% since none are infallible) and that is RegSupreme Pro, or it's little brother RegSupreme. It has a proven track record over many years of use by hundreds of thousands (perhaps more) of users. Again, as with ANY alleged "Registry Cleaner" one must use caution and prudence. And, ALWAYS..... ALWAYS, make backups!! <IMG SRC=http://www.the-highway.com/Smileys/crazy2.gif>

    Hello,
    Tried the "safe mode" approach ..with the same results. Jeff's suggestion (trying RegSupreme Pro Free 30 day trial) has found about 100 dead end registry items. Probably due to my removing many of windows programs, that can not at this point be deleted (get "access denied" or "invalid key") error message. However as for your "RegDelNull" suggestion i can't figure out (so far) what exactly you have to enter into the command prompt, or what exactly it will do. As their sample is for me somewhat ambiguous. I'll post on their forum some questions. I will post back when i have more"info"

    Jeff,
    Hello and thanks for the link, and advice! (RegSupreme Pro) im giving it a test drive 30day ,Looks like a keeper. As far as "hosing my system" it's probably just going to be part of my learning curve,Thanks to this forum and Ya-All it will be a lot less painful! I'll post back after "patch day" to let everyone know if my PC freaks out. Regards
