The Windows 11 encryption issue might result in data harm

    The Windows 11 encryption issue might result in data harm

    Microsoft is warning that Windows 11 might have a bug that can cause data damage under certain specialized conditions, including writing data to encrypted drives using BitLocker. However, the disadvantage of this method is that it will slow performance for about a month. There are two functions that are impacted by this problem. They are the AES-XEX tweaked-codebook mode with ciphertext stealing (AES-XTS) and the AES with Galois/Counter Mode (GCM) (AES-GCM).

    The Windows 11 encryption issue might result in data harm

    The issue is that both algorithms are used for data encryption. BitLocker encryption uses AES-XTS as its underlying function. BitLocker encrypts and protects your hard drive. If someone steals your laptop, they won’t be able to see your data without your PIN, fingerprint, or face recognition via Windows Hello. The bad news is that the damage isn’t fixed. The good news is that if you keep your PC up to date, you should be fine. For one thing, Microsoft’s security notice claims that only the initial Windows 11 release is at risk, and that the problem was “addressed” with a security update in June. The other worry is that after applying the patch, performance will be slowed for about a month. (Microsoft does not explain why this is, or why the one-month period was chosen.) BitLocker and enterprise load balancers, as well as disk throughput on corporate PCs, are all impacted. If you have been keeping your PC up to date, then you won’t have any problems with the bugs. There is a time in mid-July when degraded performance might happen, but it will only affect people who don’t keep their PC up to date.

    How can I tell if my PC has BitLocker enabled?

    BitLocker is only available on the Pro versions of Windows 10 and Windows 11, according to Microsoft. If you’re using a Windows 11 Pro PC with your Microsoft account, BitLocker is enabled by default. Windows’ built-in “device encryption” can be utilized by Windows 11 Home PCs. It’s unclear whether or not Device Encryption employs the AES-XTS algorithm. Simply open the Start menu and type “Manage BitLocker” into the search box to see whether your PC has BitLocker enabled. If your PC has BitLocker enabled, you’ll be presented with a Control Panel where you can change various settings. If you don’t, Windows will just ignore the request. Make sure you back up your BitLocker recovery key. It’s automatically saved in your Microsoft account settings if you’re signed in to it. If your PC doesn’t have BitLocker, it’s not necessary to turn it on. However, you may be able to benefit from hardware encryption. To do this, go to the Settings menu, then Update & Security > Device Encryption. If your PC is encrypted, you’ll see a switch to enable or disable encryption.

    Is my hard drive damaged, or am I just looking at it incorrectly?

    If you haven’t noticed any problems with your hard drive or SSD, there’s no need to worry. However, if you’re feeling uneasy, you can always scan your file system for errors manually.

    To do so, simply right-click your PC’s SSD or hard drive in File Explorer. The “Properties” subheading will bring up a menu where you may look for problems.
