Dude, get a hobby. What makes you think there's a problem? The registry is full of duplicate entries.

OK, maybe that was a bit harsh. If you have concerns you can run a registry cleaner. Perhaps something like this:

But don't overdo it. It depends on where they're located, but many duplications are intentional and necessary.

Mr. Dave:
a. I am retired and the computer is my hobby...:>)
b. oddly enough, these duplicate entries just showed up out of nowhere.
c, after loading several programs, these entries have nothing to do with them; they were duplicate before i loaded, the same after.
d. perhaps i did not phrase it correctly: can I in fact delete them: all that is different is the one ( 1 ) on the end of the duplicate
e. knowing windows as i do ( win 3.1) this is the WORST SCENARIO IN REGISTRY i HAVE EVER SEEN.
f. this is a 2.0 ghz system and it runs like a 486dx...but according to you, that would be ok......
g. Regcleaners DO NOT CLEAR UP THE DUPS. I have installed and run 5 of them, just now trying RegSeeker....will let you know .

thank you for the lead to RegSeeker...

Since those entries are not identical, why call them duplicates?

Did you actually mean "1%" ?

Oops! I meant "%1".

I have seen identical keys except for (1) after them. I too have pondered but if one is unused then its anybody's guess which one should be retained. I have my own ideas about which one is likely to be the one in use but I prefer not encourage you.

Best bet is to simply leave them there. There is no reason to assume that extra entries in your registry will make any difference to performance. They simply won't be used.

You might run a malware scan too. It'll check the registry for dubious entries. You can download the free version of malwarebytes here:

Too little ram and too much stuff running in the background can slow things down too.

Derek: thank you for your professional response:
1. have run 5 reg cleaners
2. have run 3 malware progs including malwarebyte.s
2 gig ram
2 gig speed
my main concern is that they were there one day and not the next: no %1, just a plain one ...checked it again: here is an example:

derek: here is the duplicate as it appears in the registry:

HKEY_Classes_Root;

HKEY_CLASSES_ROOT\
ComPlusMetaDataServices.ServicesMetaDataDispenser
CLSID
CurVer
ComPlusMetaDataServices.ServicesMetaDataDispenser.1
CLSID

notice that the second entry - with the # 1 one the end - has only the " CLSID ".
under both entries, the information is EXACTLY the same, only the the CurVer " is missing......once again, thanks Derek...Ed

Hey, you have refreshed my memory. Yes, I think the "exactly the same" entries I've spotted over the years did have and additional .1 (not a 1 in brackets as I said earlier). My guess is that the .1 entries are newer and therefore the ones that matter. However
I'm not certain so I would be the last person to suggest that you go around deleting the ones without the .1 because I might be quite wrong - maybe you need both.

I still think the best bet is to leave well alone, but if you want to play then you need to backup your registry first. There is a very neat little freebie out there called ERUNT which does just that. It restores the complete registry rather than remerging, so you can quickly get back to where you started if you do the wrong thing. The only risk is if you remove something that is so important that Windows then fails to start. A long story then starts LOL.

Here's a link to ERUNT:
http://www.snapfiles.com/get/erunt....

It can be useful if you want to "juggle" registries although if I restore an earlier registry I first try to match the installed state to it as near as I can. In fact I keep a Notepad file in with the restores and always record the date and major changes when I save a new registry. System Restore (XP) is a different matter because that restores the whole system, not just the registry.
