Do you own a Lenovo laptop PC with less than 8 GB of RAM? What follows may well concern you. Last week, Microsoft deployed a seemingly innocuous update aimed at filling a security flaw spotted on the very dispensable (but nevertheless installed by default with Windows 10) Internet Explorer . Potentially more important than what Microsoft wants to say in its release notes, this patch (KB44832229) propels the Windows 10 Build to number 14393.2670 and causes the PC to restart. A restart, surprising for an update of this type, which precisely poses a problem for certain machines marked Lenovo.
According to SlashGear , Windows would indeed experience all the difficulties in the world to boot normally on certain Lenovo laptops after installing this famous security patch. A relatively painful manipulation for the uninitiated would then be necessary to solve the problem … and regain full access to his PC.
Note that this failed update comes after the succession of blunders made by the Redmond firm on the occasion of the launch of the infamous October update of Windows 10, the deployment of which on our PCs has been delayed. several times following a succession of technical problems. In terms of software, this end of the year is therefore a bit complicated for Microsoft.
Go through UEFI to troubleshoot an affected PC …
To unlock a Lenovo laptop PC that can no longer start normally, the solution is to go to UEFI (new version of the BIOS, used on PCs launched after 2012) using the access command chosen by the manufacturer (this key varies by brand and sometimes changes depending on the model).
Once UEFI is reached, the user must endeavor to deactivate the “Secure Boot” mode. A relatively straightforward action on paper, but it can get quite frankly complicated if the hard drive or SSD Windows is installed on has been encrypted using BitLocker (Microsoft's encryption utility). If the user is at the origin of this encryption, he will then have to find the code provided at the time of the encryption.
Unfortunately, some PC models may have had their SSD or HDD encrypted from the factory. This is obviously the case with certain models of Lenovo laptops . It will then be necessary to check in the documents supplied with the device whether the key necessary to unlock BitLocker is given. Otherwise, recourse to the manufacturer may be necessary. Microsoft, however, promises to launch a new corrective patch as soon as possible. In theory, it should correct the problem.
