As we discovered, after installing a new update under Windows 10, millions of computers are out of service, which means that they can not be used anymore. This happens because the user simply sees a black screen at startup, ie the operating system itself does not turn on.
Many users have already found a way out of this situation: they have reset Windows 10 and lost all their personal data. However, it is better not to do it. It all started with the fact that Microsoft released hotfix KB4467691, intended to remove a single breach of the Internet Explorer security system. Yes, this web browser uses a bit in 2018, but the fix automatically installs the operating system. It fixes the vulnerability by which attackers could force the old browser to corrupt the data, then upload malicious ones
Immediately after the installation of the fix, many Windows 10 computer owners get themselves are aware that they were not very lucky. Experienced way has been able to discover that problems are prone to laptops with less than 8 GB of RAM, and especially Lenovo. If there is a problem, the electronic device is turned on, but nothing happens. Microsoft has already acknowledged the existence of problems and promised to resolve them quickly, but that does not happen.
In the description of the patch KB4467691, it is stated that it "is incompatible with some laptops", in connection with that to install at your own risk. If the computer does not turn on after installing the update under Windows 10, you can try to disable the boot safe option via UEFI. Some users helped. Another, pretty obvious, will have to reinstall the operating system or restore it to the state that was before the malicious patch was installed.
