The window title is now solid color without any transparency, but the task bar still has the blurry transparent looks as one can see from the pictures.
Or do I misunderstand the names for the different bars in Windows' UI?

That depends on what you sell. A product or only a license.
If it's only the license that's being sold than you can pretty much define what the user may do and what not.
There's an infamous case about oracle licenses and if they may be sold on the second market.
German court ruled that is not allowed since you do not buy the software, but only a very special license.

If you sell some physical work though (and in some cases a cdrom would be enough to qualify for that), the ownership goes over to the customer and he/she may do with it whatever he/she likes.

In germany any contract can only be binding if you know the terms before you sign it.
When you purchase software in the store and are presented with an EULA after you already purchased it, that agreement is not binding to the customer.
EULAs for Download content might be valid for german customers though unless terms are diametral to general law.

Isn't scrolls a quite common word making it untrademarkeable?
Especially when it comes to role playing games, most of them use the word in the normal gameplay.
That would make it pretty nonsensical to grant a trademark on that word for using it as the product's name.

This is not even taking into account that they don't use their trademark enough for it being confused with the Mojang game.
The official name of their Elder Scrolls series contains the word, but they are most commonly known and marketed by their subtitle.
Even the link between a game with scrolls in it's name and the Elder Scrolls series is only in my mind for this stupid action, I wouldn't have made any connection otherwise.

There are some (pretty big) rural areas here in Germany, where people can't get xDSL or cable even if they wanted.
I know of at least 5 villages with about 100 citizens each in 20km radius that don't have any chance but dialup networking for Internet Access.

In some areas you can get Networking via UMTS/(E-)GPRS, but mostly it's not faster than POTS or ISDN Dial Up.

That's also why some of the lower frequencies used for LTE/4G Networks were given to provider with the prerequisite to install networks in those areas before the frequencies may be used in cities.

I'm diabetic Type 1 since 20 years and have read about stem-cell therapies for ages. There were clinical studies with adult stem cells from the patients own spinal cord. What I want to say is that these testicle stem cells and the ones from deceased pancreas are not the only sources. In the last clinical study with own stem cells they found out that the biggest effect is the stimulation of remaining beta-cells (Yes even Type 1 patients have some remaining cells) to produce a significant amount of insulin. Whereas only fewer than 1% of the stem cells integrate into the fabric and mutate into something comparable to beta-cells. As far as I know they don't suffer the problem of being destroyed by the own immune system. Though I don't know if this is because the auto-immune reaction is only active for some specific time or because the stem-cells are not completely identical to beta-cells.

Have a look at the other article of this author he also references, in which he talks about allowing intrusive ads for free premium services that serve ads in order to make up for the cost of running these. In special he talks about web/cgi Proxy services that have to change their IP multiple times a day in order to provide their service to users in censoring countries and that allowing even more intrusive ads for services like these is ok with him and should be with all of us. I'd also like to see such a function. But more as a developer tool than for reporting abusive popups.
