Maybe the most important thing to note is that Ashampoo UnInstaller installs a driver & service -- if you Google on the driver file name [ifs32.sys or ifs64.sys] you'll get some results talking about crashes & BSODs. That doesn't necessarily mean that you'll have problems, but note or remember that you installed that driver, so in case of a problem cropping up in the future you'll know to at least try removing Ashampoo UnInstaller 9, or renaming the Ashampoo folder in Safe Mode etc. when you try to fix whatever.
Bearing in mind that no uninstaller app I'm aware of will show you everything that changed, or offer to revert those changes it hides from you -- some things involve risk, which to the uninstallers is unacceptable -- I added it to a Win10 VM to play with. I don't have a good way to monitor installs in Win10, so figured I'd give it a shot. Historically an Ashampoo giveaway is forever -- I've only seen one exception -- so I *should* be able to install it elsewhere later on if I decide to. There are 32 & 64-bit versions, and the only hints at bloat [so far] are the multiple language files, and several registry entries for the context menu. It uses the Inno Setup installer, and there's nothing hidden once those files are extracted using UniExtract. Files are added to the program's folder, the user AppData Local folder, and the Public Docs folder.
