Most users are familiar with the concept of an upgrade. On the TV screen and on the Internet, we constantly see advertisements about new software, PCs, and we know that as new versions of hardware and software are released, we need to update our equipment. But not everyone faced downgrade.
The simplest downgrade option can be found when compatibility problems arise after purchasing a new computer or operating system. For example, it is impossible to connect something from the existing peripherals to a new "machine", to run an old program on it for work. In such a situation, some stop at using two computers - the old one for work, the new one for games and the Internet.
Another example of downgrade can be found when new operating systems are released. They are often preinstalled on laptops, but on inexpensive laptops they slow down a lot. are quite demanding on the "hardware" and to solve this problem, users reinstall the OS, returning to an older version, which loads less equipment.
Historical note: Microsoft has a so-called open downgrade, that is, if you purchase an OS license, you can legally return to its older version. For example, you can downgrade Windows Vista Business, Ultimate to Windows XP Pro, Pro x64.
Thus, downgrade is the return of old components, hardware, OS and software, which is due to various reasons, among them the inability to run the necessary software versions, to work with the necessary equipment (which is impossible or too expensive to replace).
Of course, more often downgrade is associated with the inability to find a replacement for the necessary working tools or with too high costs for acquiring new ones. But you can also find downgrade due to nostalgia (some gamers in adulthood reanimate old computers and play games of their childhood, system administrators install old OS versions or use old hardware to solve current tasks for economy or entertainment). That is, downgrade can still be considered a hobby.
