pstein Posted March 7, 2022 Report Share Posted March 7, 2022 After having troubles with re-associating an image format with file extension *.webp to another image viewer I did some investigations. I found two related file extension keys: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.webp and HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.webp" MIND the trailing double quote: " The last entry is obviously nonsense. I am not sure where it comes from. Maybe some other crap software. To get rid of it I run a DeepScan with Wise Registry Cleaner v10.7.1 and yes it found the culprit entries (see attached snapshot). So I ticked them all and start cleaning. Unfortunately Wise registry Cleaner was NOT able to really delete these registry entries. I guess it is because it is confused by the (single) double quote This is a bug. WRC should be able to completely delete them. Can this be fixed in the next reelease. Thank you Peter The exported registry (including the valid one without the double quote) entries look like Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.webp] [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.webp\OpenWithList] "a"="Corel Paint Shop Pro Photo.exe" "MRUList"="ba" "b"="Imagine64.exe" [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.webp\OpenWithProgids] "Imagine.WEBP"=hex(0): [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.webp\UserChoice] "ProgId"="nomacs.webp.2" [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.webp"] [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.webp"\OpenWithList] "a"="xnview.exe" "MRUList"="ba" "b"="Imagine64.exe" [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.webp"\OpenWithProgids] "webp\"_auto_file"=hex(0): [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.webp"\UserChoice] "Progid"="Applications\\Imagine64.exe" Link to comment Share on other sites More sharing options...
