KB4056892 – Emergency Windows 10 Update to Address Processor Flaws

The 2018 year started with some pretty major exploit discoveries. Named Meltdown and Spectre, these exploits are perhaps the most dangerous processor flaws that affect almost all modern processors. The security vulnerabilities affect whole generations of computers and devices of all types that use the quoted chips. As a consequence the hackers can gain access to sensitive information that is being processed by the computers.

According to Intel’s initial news report, “contrary to some reports, any performance impacts are workload-dependent, and, for the average computer user, should not be significant and will be mitigated over time.” As for any advice Intel has for consumers:

Check with your operating system vendor or system manufacturer and apply any available updates as soon as they are available. Following good security practices that protect against malware in general will also help protect against possible exploitation until updates can be applied.
