Hi, I have checked the link and also saw some of the posts.
i did as you say in the options, advanced menu. The second toolkit.telemetry is by default in false position and so left it as it is . But on completing the commands , suddenly i experienced black screen , with no monitor, no browsing .. etc.
i just saw the monitor blue light just staying for some minutes. I just force close the computer by power off and then rebooted . The first boot was not success , but second success. Is that anything to do with disabling this telemetry entries
