A bit too much bloat for my tastes, though not anywhere near what you see with Nero. The app itself is capable enough, though it doesn't take much to burn optical discs -- the free ImgBurn comes in at around 3 MB. A lot was made in the comments of the fact that Ashampoo Burning Studio 2020 will check in with Ashampoo's server(s) from time to time to make sure the license is valid. That Does Not imply any sort of spying, which can easily be verified using the free Nirsoft app, Cports. It tells you what's accessing the network, who's being talked to etc., and while the Ashampoo app's running there's nothing Ashampoo listed at all.
Ashampoo Burning Studio 2020 does include ffmpeg code libraries, but it doesn't offer video encoding for video DVD or Blu-ray, nor does it include DVD or Blu-ray menu authoring -- if that's what you're after maybe get Nero Ultimate, though the authoring tools are really pretty basic. For Ashampoo's selling price of $21, or less [I don't imagine anyone pays full price for their software], IMHO you shouldn't expect stuff like disc authoring. If that's a problem use free, open source authoring apps. What you do get that's not in ImgBurn is file backup, a simple jewel case inset & printable disc image editor, and Ashampoo's scratch protected data discs.
Monitored in 32-bit Win7, Ashampoo Burning Studio 2020 adds 2,355 files, in the program's folder, in ProgramData, in Users\ [Username]\ AppData\ Local & Roaming, and in C:\Windows\ Installer\. Many of the large number of files are alternative language & associated image files that could of course be deleted. Most of the 790 new registry entries are not *strictly* needed either... there's a lot from the included Microsoft C/C++ runtimes, which most already have installed, plus lots of entries associating file name extensions with the software, and a bunch of autorun entries [don't use autorun].
