Update from Microsoft protects Windows 10 Mobile handsets from Meltdown and Spectre


Microsoft has rolled out an urgent security update to all supported versions of Windows to help protect against the recently discovered bug found in billions of devices worldwide.

For Apple MacOS users, checking for updates is more straightforward. The "frustrated" user, for example, reports that beyond that laptop, one desktop with a different AMD chip and three laptops with Intel chips have successfully updated. Even if that is successful, however, the operating system quickly attempts to reinstall the PC-freezing patch, they say.

This is our new weekly column that rounds up all the latest news from the Microsoft campus and throws it on a page with a bit of observation and commentary. "Customers will not receive the January 2018 security updates (or any subsequent security updates) and will not be protected from security vulnerabilities unless their anti-virus software vendor sets the [required] registry key", Microsoft says.

But that registry requirement doesn't appear to be causing the problem with AMD processors, as some users report that they have compatible anti-virus software running.

Microsoft has already issued emergency patches for Windows 10 users.

Doing so will download the Windows 10 Upgrade tool and you can run this and follow the instructions to upgrade a Windows 7 or 8.1 device to the latest version of Windows. In a statement, Intel said: "Intel and other technology companies have been made aware of new security research describing software analysis methods that, when used for malicious purposes, have the potential to improperly gather sensitive data from computing devices that are operating as designed".

Security experts say it's not clear how frequently real-world attackers might attempt to exploit these flaws.

AMD's CPUs may have been immune to Meltdown and Spectre, but it turns out they are not immune to Microsoft's patch for the same.
