Store the view setting for File Explorer search results
To summarize the comment from @w32sh, add the following registry key:
HKEY_CURRENT_USER\SOFTWARE\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell\{7fde1a1e-8b31-49a5-93b8-6be14cfa4943}
Then, add the following DWORDs under that key:
"LogicalViewMode" = 1
"Mode"= 4
The results should pick up immediately by launching Windows Explorer and performing a search.
If that does not work for you, then delete (or, for safety until you've tested, rename) the following two keys:
HKEY_CURRENT_USER\SOFTWARE\Classes\Local Settings\Software\Microsoft\Windows\Shell\BagMRU
HKEY_CURRENT_USER\SOFTWARE\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags
