Fake system data, how to recognize?

Question

Iron

And so perhaps the question is stupid, incorrect, etc..
Look, for example, a person got confused and made a "left" characteristic of the system (General information about the system!
Frequency, number of operational).
rummaging in the registry or through prog.
So they don't crash after a reboot.
So how can you understand that they are "leftist"

Answer 1

boot the computer from the Live system (disk / flash drive) and see
if it remakes at least 20 times ㋛

Answer 2

Test for real performance and memory, the rest according to the circumstances.
Bios can be faked as well as the appearance of the nodes.

Answer 3

Normally. The right question is half the answer.
1) Why would anyone change the display of PC characteristics?
- If you are afraid that you will buy a PC that does not meet the declared characteristics, then checking the BIOS or a bootable USB flash drive will be enough.
- If you want to control the configuration of a PC in a corporate network so that the "User" cannot "pull" the RAM unnoticed, the issue is resolved by delimitation of powers and standardization of the installed software.
2) What are the intended resources of the "intruder"?
- None. Changing the "System Properties" picture in Paint is its limit.
- Any. Writing your BIOS, which will produce any results it needs. as one of the options. The question is what is the benefit, and how does it compare with the costs.
Those. the method of hiding information will depend primarily on the reason.
