Yes, full-disk encryption can affect a system restore by requiring a recovery key, causing boot locks, or blocking third-party tools. It may trigger security prompts or prevent operations if the system does not recognize changes made during the restore process.

How Encryption Interacts with Restore

• Recovery Key Prompts: Running a restore from the recovery environment often trips full-disk encryption like BitLocker, forcing you to type in a 48-digit recovery key before you can proceed.
• Third-Party Software Conflicts: Enterprise or third-party encryption tools (such as Dell Encryption) can flag system file changes from a standard Windows restore as tampering, resulting in critical catalog errors or failed extractions.
• Data vs. System Files: Standard system restore points roll back operating system files and settings, but they do not touch or recover encrypted user data files.
