Before handing a PC to a repair shop, back up important data, sign out of sensitive sessions when practical, and ask what access technicians need. Routine cleanup cannot guarantee that private data is irrecoverable.
Back up essential documents and verify the files are readable from a separate device.
Note encryption status and recovery keys. Keep recovery information secure rather than giving it out casually.
Move private files off the computer if the repair does not require them. Use drive-appropriate disposal or reset methods for stronger requirements.
Sign out from sensitive accounts where practical, understanding that deleting cookies may disrupt normal use.
Ask the repair shop whether a temporary local account is sufficient and how they protect customer data.
No. A targeted cleanup is not a substitute for a recoverable backup, malware removal, or device sanitization.
No. Review affected files, user profiles, and drives before deleting anything.
No. SSD TRIM and wear leveling make overwrite-based expectations different from HDD behavior.
