I can reduce the number of items in the Most Recently Used list in Photoshop Elements, but unlike in plain Photoshop I can't truly clear the list in Photoshop Elements. That means, when I then re-increase the number of items in the list, instead of still showing nothing in the list (as it would if it were truly cleared) it just puts back the MRU entries that had been there before. This means that the actual list is stored somewhere on the harddrive. I already found it in the registry at HKEY_CURRENT_USER\Software\Adobe\Photoshop Elements\16.0\common\settings\Elements MRU but even that isn't the only place this data is hiding on my harddrive. If I close PSE, and then delete the registry entry, and then restart PSE, it (as if by magic) regenerates the registry entries, and repopulates the MRU list in PSE. How can it know what to regenerate in the registry, when the registry was the only place that held that info, and that info had been deleted from the registry? The obvious answer is that the registry is NOT the only place this MRU info is stored.
It seems that Photoshop Elements, is (almost like a computer virus) attempting to persist certain pieces of data (such as the MRU list), so as to make it nearly IMPOSSIBLE to actually truly clear the MRU list. If anybody here knows just how PSE is able to persist this MRU data. Please let me know.
Some things I've considered that PSE might be doing to persist the MRU data are storing them in in ADS (alternate data streams) as well as directly writing them to unallocated harddrive space.
Any help discovering the location of this MRU data, so that I can clear it, would be MUCH APPRECIATED.

There was a bug in PSE15 but it may be possible to use the same fix in v16 or v17 by navigating to the Editor folder to find machine prefs. Substitute your own user name for mine. See my blog for full details.
