Removing a dll from boot up?

Would anyone know where the dll's get loaded from on boot up?
there must be a file the hold the dll's that at boot up it knows which
ddl's need to be loaded.
At boot up I get a msg that a dll could not be loaded. I would like to
get rid of this msg.

Thanks

 

Depends on the .DLL
For Windows .DLLs, most are located in the system32 folder.

For any installed applications..... who knows?

We might be able to advise you better if you could post a screenshot of the error, and post it here.

 

It's an installed application. I know where the dll is but I'm trying to remove it from boot up. I don't want it to load it at startup.

 

Then you probably don't want the application itself running at startup. That's more than likely what's calling the .DLL

There are instructions on managing startup programs at this link, as well as other tips for speeding up the computer.

 

Here what got me to this spot.
Someone installed an app Registry Cleaner.
I 1st tried to remove it using the Control Panel "Add or Remove" but would not uninstall.
Then tryed to remove it by running the uninstall that came with the app.
Still no good.
Then I went into regedit and removed things with the name of "registry cleaner"
It still loaded.
Then did a search on the HD for "registry cleaner" and deleted all but the dll because it would not delete because it was running. I renamed it and rebooted and now it comes up stating that it can not find it.
What I'm trying to figure out is what is looking for it at boot up time so that I can remove it.

 

Please.

 

I can't seam to paste the image into this page.
The following is what it states:
{Cannot find import; DLL may be missing, corrupt, or wrong version
File "regdean.dll", error 126}

 

the problem is not killing it. it's stopping the boot up from trying to load it.

 

should I rename it back so that it loads??

 

ok I ran Process Explorer and did as you told me to do but found no regdean.dll.
I assume that's because it's not loading it. There must be a list of dll's that boot up used to know which dll to load.
