So register with 1852-9515?

Well I would love to fix this:

When trying to run some files I get this error:
A REQUIRED PRIVILEGE IS NOT HELD BY THE CLIENT

Tried running as ADMIN ( I am logged as ADMIN anyway)
Tried changing different settings for the file, nothing works.
I get this error sometimes for some executables.

Any ideas anyone?

Watch out this developer has not taught the program about all the environmental variables for standard folder locations. So certain perfectly valid registry keys will be flagged as errors because the program does not know how to parse variables in paths e.g.

%CommonProgramFiles%\System\ado\msado26.tlb

this program thinks that is an abandoned entry but it really points to:

"C:\Program Files\Common Files\System\ado\msado26.tlb"

The file exists exactly where the key says it is but the program is not built to understand the perfectly legal and legitimate registry entries path syntax.

I have absolutely no doubt in my mind that there will be hundreds if not thousands of similar false errors that IF you allow thus to delete them all certain core modules within windows will cease to function and may not even load at next boot up... which might speed up booting but at the expense of windows operating properly with all security layers intact. At this point in time I am going to stop searching through the list of errors simply because in my opinion this is not programed by a developer knowledgable enough about the windows registry and officially documented registry usage to safely and competently design and impliment registry diagnostic and repair/cleaning tool.

The key provided activates the program without issue or need for internet connection. While it is unlikely there will be an update any time soon from the previous development history it is advisable to delete autoupdate.exe or rename it or block its access to the internet to prevent it ever checking for an update which we would not be entitled to with this giveaway license.

I note that the change log shows this version is two years old and the bugs people are reporting today should have been fixed by now... so looks like this product has been abandoned from any development investment.

The best one is "Registry first Aid v10! " , and you still may have some issues in the end. Best not to touch the Registry!

Says the activation key is invalid. [?????????]

Downloaded easy and works well and very officient

... and with all the issues, they still have over 80% positive rating! Amazing!!

"and any error messages you saw whilst using your computer previously will be gone"

They cannot be serious. There is no software that can do this.
OK, there is. It's "format c:"

Registry files are very small and do not consume much in the way of storage space. Unless you are an expert user it is not a wise thing to interfere with these files, removing the wrong registry file(s) can severely damage your system. Windows "knows" which files are valid or invalid and will simply ignore the redundant files, so-called registry cleaning will not improve your systems performance. In my experience the only time invalid registry files cause problems is when the user has attempted to modify them. Best advice is if it ain't broken don't fix it.

The only time in my experience has a change to the registry improved performance is if there is a key pointing to a program that is not in that location and Windows searches for it.

System Internals from Microsoft which is free identifies the start up issue and allows you to deselect it to see the improvement. Avoid touching the wow64 errors as they are/were a false positive.

The utility you should use is autoruns.

Use this with extreme caution. The claim that "Once your Registry has been cleaned up, you will likely notice a performance boost and any error messages you saw whilst using your computer previously will be gone." is quite simply, a lie.

It is exceptionally rare for a registry cleaner to actually fix any errors or problems you have with your computer. In addition to this, it's much rarer for a registry cleaner to make your computer run any faster or better. No matter how many hundreds or even thousands of so called errors registry cleaners find, deleting them is usually pointless.

Today's giveaway, just like at least 99% of other registry cleaners, will sometimes mistakenly think that valid registry keys are errors and want to delete them. Understandably, sometimes deleting valid registry keys will actually cause problems. It's more likely that today's giveaway would cause problems, than fix them.

If you are having issues with your computer, running tweaking.com's excellent Windows Repair software is a good starting point. Not only is it free, it can actually fix a lot of PC issues and it's exceptionally rare for it to cause issues. There is a paid Pro version too, but you can do all the repairs you need with the free version.
