What is the problem on the laptop?

Question

Windows

On a laptop with Windows 7 Premium installed, the interface changed dramatically at the XP level, Internet access was blocked, i.e. the wi-fi network list icon disappeared with the "Off" status blocked in the control panel and the icon cannot be returned and the Internet itself when you open the browser too no, changing the brightness does not work (although when you turn on the laptop, the brightness is at maximum, but only then at a minimum that cannot be increased), the sound disappeared, all system applications like "Diagnostics of problems" ask permission to change, the ability to roll back the system is blocked, Windows Defender is simple is blocked and does not want to turn on, and to the topic about icons: In the control settings, all icons have a blocked status and cannot be changed in any way,all screen personalization options are disabled and some mega-contrasting styles are available worse than Windows XP level, Aero does not work with its themes, you can’t install the classic Windows 7 theme, you can’t change the quick access panel in any way, the Problem Diagnosis application is simply blocked.
Photos of the laptop are attached: (I apologize in advance for the Polish language, because I live in Poland and did without changing the language to Russian, I tried to translate)

Main part: The system rollback utility does not work properly on this system. Error code: 0x80042302

System Icons: Status:
Clock On
Volume On
Network Off <--That's what is blocked
Power supply On
Alert Center

On Just all the icons with a blocked status

This is how the interface of the "seven" looks like
