Hi all, I've been a CCleaner user for years, and have only recently discovered what appears to be a bug in CCleaner. It appears to somehow be corrupting the registry so that the explorer "Open With..." feature that appears on the right-click of most files...well it doesn't really work any more. Seems to be pretty reproducible, and I've noticed (through a lot of googling) that other people who experience this problem seem to have these situations in common: WinXP Pro, Vista Pro, Win7 Pro 32 or 64 bit processors Have used CCleaner This is just a suspicion, not a confirmed bug report. Here are the symptoms: For any file type, the "Open With..." explorer menu item is there, but it never offers up a list of programs to use (in other words, the submenu doesn't appear), even when there is a valid list of programs (OpenWithList or OpenWithProgids) for that file type in the registry If you select the "Open with..." item, you are offered the wizard for adding programs to the OpenWith list (this is correct), but the file name is corrupted with an " after the file extension, like this: foobar.txt" By using that wizard, you will be creating a new extension (in the example, .txt" in the registry and building a new set of OpenWith lists there Even after you've done this, issue #1 persists: you are not offered the Open With list as a submenu; consequently, you have to go through the open-with-list-builder wizard each time I've spent a lot of time inspecting all the parts of the registry that are supposed to handle this feature, but I've not found anything obviously out of order. Anybody else seeing this? I'm happy to fix the registry myself if I only knew where to apply the fix. Thanks in advance for any info / hints you can provide.
