Don't spoil Desktop Software Engineers with your Mobile First solutions, think about it

Once upon a time, my girlfriend started using Instagram. She asked me to sign up for it and subscribe to it. I tried — I couldn't do it because you couldn't register at Instagram from a desktop computer. I then thought — how weird people are. Well, what kind of fool would make a software product that can't be used with a normal computer? They won't succeed, and this Instagram will be a marginal service for a bunch of strange women, who for some reason don't like desktops.
It has only been a few years, the market has put everything in place — and the biggest fool was me. And the geniuses at Instagram predicted how and where everything would develop. Today, most of the user applications are made primarily for mobile platforms. At best, they include a universal web client, which is still optimized for mobile phones. Because users love iPhones, not computers. Business people sat down, counted, and made a decision — let's make more money, let's have mobile First everywhere.
One of the modules in the Windows kernel provides support for combining a set of file operations into an entity known as a transaction. Just like in databases, these entities are isolated and atomic. You can make some changes to the file system that won't be visible outside until you commit them. Or, as an alternative, you can always rollback everything. In any case, you act upon the group of operations as a whole. Precisely what needed to preserve consistency while installing software or updating our systems, right? If something goes wrong — the installer or even the whole system crashes — the transaction rolls back automatically.
