We do *not* create multiple-resolution thumbnails. What you see (with low resolution) is what is there, nothing more. And even that is too much, making the configuration file several megabytes. IMO: just "no" to "let's generate a whole *series* of raster images with different resolutions".

The explanation may have been insufficient.

The image of the document stored in "configuration file" is a png file of 512x512 pixels.
The thumbnail image displayed in the Start Center is a reduced version.
Therefore, the enlarged image is the original saved image, and there is no need to save more than one image.

-1, the thumbnail preview shown in the Start Center already takes too much room in the User's profile registrymodifications.xcu. It makes the user profile more prone to errors. 

Also some comments on see also bug 151926

IMO, this is a bug; but I seem to remember some issue that could be "fixed" recently to cause this four-times enlarged image in the profile. The PNG size should be (restored to) 256 pixels.

Wouldn't expect right click to zoom in or to execute any other action. What I could imagine is to zoom the whole start center per ctrl+wheel. Or provide some expert option for the default size.

But why do you want to enlarge the thumbnail anyway?

Enlarging the thumbnail was -1'ed in c1 and c3 (and I agree) and is not a solution.
