I recently went through and changed some registry entries so that only I had ownership and access. I suspect one or more of the changes resulted in a software installation failing. The installation program indicated it could not write a certain entry, but only identified the value to be written, not the location in the registry.
Unfortunately I made the mistaken of not keeping track of which ones I changed.
Is there some way to search through the registry to identify entries based on their permission? In my case, I would be trying to find entries owned only by me.
