Internet Explorer DOM Storage Registry Entries

I'm using Internet Explorer 10 on Windows 8 64-bit and noticed that there are DOM storage registry entries for a large list of websites. Would it be feasible for CCleaner to clean these website entries?

They are stored at the following registry location:

HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\windows_ie_ac_001\Internet Explorer\DOMStorage

You can ask if someone will create a winapp2.ini cleaner for it in the winapp2.ini topic located at:

That way you won't have to wait for CCleaner to officially support it.

I may well be wrong but I dont think winapp2 can touch hkclassroot .can it?
