How could Ccleaner kill Windows?

Question

Malware

I don't even know how to phrase the question. A friend has already raised the topic with such an error:
Could the RAM kill the computer?
But then he sinned on a new plate. I cleared the browser cache with ccleaner and the same result. Very strange nature of the error. And it's not clear how to treat now without a complete reinstallation of the wasps?

Windows dies at startup, and there is nothing to write to the flash drive. Somehow, a useful utility turned into a terrible virus. The question is, what could she have done there?

Answer 1

With the release of Windows 10, Microsoft recommends not using programs to clean up the registry and operating system files to increase disk space and speed up OS performance. On Reddit, there is still a controversial discussion among many users about the benefits and harms of using such utilities.
After updating Windows 7 and Windows 8.1 to the latest Windows 10, the operating system removed CCleaner itself, but after updating the application, which is one of the most popular of its kind, it is now positioned as fully compatible with the latest platform.
With the continued use of such utilities, the corporation itself recommends that users be sure to back up and create a system restore point, so that in which case, it would be possible to restore the OS without any problems.

Answer 2

How could Ccleaner kill Windows?

Very simple - this is its main purpose.
This utility cleans the registry, guided by its own considerations of what is needed and what is not.
In general, if something is good for Ccleaner, then it is not a fact that it is good for Windows.
I classify such utilities as malicious software by default.

Answer 3

Refuse such utilities starting from Win7 and higher.
Set restore points and you will be happy.
