An update offered by Microsoft will slow down your PC’s performance, but it’s for its own good.
This is a thorny problem for Microsoft. The recent versions of its operating system, Windows 11 and Windows Server 2022, have integrated a new bug concerning data encryption. The kind of bugs that can corrupt your data and cause you to lose valuable files.
Fortunately, the firm reacted quickly with a security update that fixes the bug and prevents data loss. This comes at the cost of lower performance.
A problem on recent processors
This bug is caused by the use of the Vector Advanced Encryption Standard, or VAES, instructions. These are the instructions present on recent processors and which make it possible to speed up encryption or decryption operations. This is particularly important today when we want all our devices to encrypt data by default, for better security of our privacy.
VAES are more particularly part of the AVX-512 instruction set found in Intel processors since the Ice Lake architecture, that is to say the 10th generation of Intel Core processors. At AMD, support is planned for Ryzen 7000 based on Zen 4. In other words, no processor released today.
How to fix the bug?
Microsoft therefore strongly recommends downloading and installing the June 23, 2022 security update as soon as possible. This comes at the cost of a reduction in performance, due to the deactivation of these instructions.
In the file dedicated to this bug on its support site, Microsoft also recommends installing the July 12, 2022 security update.
Let’s face it, few of us have the right safety reflexes. However, our smartphones, our tablets and our PCs house a great deal of private data. So you are surely interested in following these…
