I have a very hard question.
I searched in Regedit a Registry Key called:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node
as suggested in:
Libraries Folder - Add or Remove from Navigation Pane
I assumed to follow this as my Windows version is 64-bit.
I searched the key on the original .REG for "Start_Menu_Videos_Open_to_Users.reg" and I found it was pointing to an seeming 32bit key of the registry, then I looked after that key in Wow6432Node and I FOUND IT, so I put the same value of the specific String ("ParsingName") of the .REG file IN the Wow6432Node String.
I mean I searched this:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\
FolderDescriptions\{491E922F-5643-4af4-A7EB-4E7A138D8174}]
"ParsingName"="::{59031a47-3f72-44a7-89c5-5595fe6b30ee}\\{18989B1D-99B5-455B-841C-AB7C74E4DDFC}"
and copied in THIS key
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion
\explorer\FolderDescriptions\{491E922F-5643-4af4-A7EB-4E7A138D8174}]
"ParsingName"="::{59031a47-3f72-44a7-89c5-5595fe6b30ee}\\{18989B1D-99B5-455B-841C-AB7C74E4DDFC}"
BEING THE ONLY DIFFERENCE the Wow6432Node sub-key. THE BIG PROBLEM IS that now I look into Start Menu to find that now there's NO link nor menu in there, the "My Videos" option had disappeared! Why did it dissappeared? In first place, when I applied the .REG file without editing the Wow6432Node sub-key, this method didn't worked as promised.
Thanks in advance.
