I am running Vista Ultimate. I keep getting the following errors that it "failed to remove" some registry entries and that "Access is denied or invalid key". See the entries below. I have the most recent update as of 9/7/08. Why do I get these errors and how do I fix the problem so that the items are removed? Please note whether or not the solution I'm given is a permanent solution or a workaround. Thanks, Steve

I am assuming you have a Vista operating system ...

"Why do I get these errors ..." -- if you posted the Registry Cleaner "Error description" for at least one of the items, it might provide a clue.


"… how do I fix the problem so that the items are removed …"

  • The first key in the list apparently concerns Microsoft's Internet Information Services (IIS). For whatever reason, MS protects IIS items, as well as some others, by making userid TrustedInstaller the only one with "Full control" permissions. You can confirm that by checking the permissions of a few items in your list with RegEdit. The keys (the first one anyway) are not on my Vista system, so I can just speculate.


    As a workaround, you can put \Interface\ in the Registry Cleaner "Ignore words" tab.


    It may be that PowerTools cannot remove the protected keys. If that is the case, a "permanent solution" is for a future version of the program to ignore them automatically.


    Perhaps the developer will confirm or correct these speculations ...

The last key in your list (first occurrence of {F9753CE4-B8A8-433A-977B-860F8469EE10}) is on my Vista system. It is shown below via RegEdit export.


What does it look like on your system?

I have experienced exactly the same problem in Windows XP as well as Windows Vista Business Edition and Vista Home Premium.

The following is from my Windows XP machine:

: The registry fixing procedure is now complete. It was possible to correct 0 items out of 71, 71 items had to be removed in order to fix the problems. You can undo all the changes from the backups.



I really want to delete these obsolete keys. That's what I bought jv16 for, after all!

Thanks. I use Vista Ultimate... After a little more examination I determined that TrustedInstaller was the owner. So I changed the ownership and permissions to manually delete these entries without a negative effect to my system so far.


Thnaks, Steve

"Why do I get these errors ..." -- if you posted the Registry Cleaner "Error description" for at least one of the items, it might provide a clue.


"… how do I fix the problem so that the items are removed …"

  • The first key in the list apparently concerns Microsoft's Internet Information Services (IIS). For whatever reason, MS protects IIS items, as well as some others, by making userid TrustedInstaller the only one with "Full control" permissions. You can confirm that by checking the permissions of a few items in your list with RegEdit. The keys (the first one anyway) are not on my Vista system, so I can just speculate.


    As a workaround, you can put \Interface\ in the Registry Cleaner "Ignore words" tab.


    It may be that PowerTools cannot remove the protected keys. If that is the case, a "permanent solution" is for a future version of the program to ignore them automatically.


    Perhaps the developer will confirm or correct these speculations ...
