A clean install of Windows 10 or 11 can automatically enable disk encryption with Bitlocker. The main apartment system and all hard drives will be encrypted.
Bitlocker protects data on the computer from unauthorized access by encrypting partitions and drives.
Microsoft says of BitLocker: “Device encryption is a Windows feature that provides a simple way for some devices to automatically enable BitLocker encryption.”
The problem is that the encryption process happens automatically in this case, and many users may not know about it. This can lead to problems, for example when reinstalling the operating system without saving the Bitlocker recovery key or using a Microsoft account.
Access to your files will be lost in the worst case scenario.
