Should I wipe my laptop before giving it for repair?
Only if you can afford to, and it is rarely the only choice. A factory reset protects your files, but it takes hours, you must back up and reinstall everything afterwards, and it is impossible when the fault is the reason you cannot back up. Deleting files is weaker than it sounds, because deleted files are often recoverable. For most people a better balance is: back up, sign out of every account, give the technician a separate Windows account, move or encrypt what matters most, and keep a record of what happens while the laptop is away, so you are not relying on trust alone.
What each option actually protects
A factory reset is the strongest protection for your files, because there is nothing left to look at. It is also the most expensive: backing up, resetting, reinstalling your apps and restoring your data can take a full day, and a technician may still need a working system to test the repair. If the laptop will not boot, it is not an option at all.
Deleting sensitive files and emptying the recycle bin feels like protection but is mostly not. On many drives deleted files can be recovered with free tools until the space is overwritten. Taking out the storage drive works well for some repairs, such as a screen, but not for anything that needs the system running. Staying with the laptop while it is repaired is excellent when a shop allows it, and most do not.
Keeping a record is different from all of these. It does not reduce what is on the machine; it tells you what happened to it. That matters because, in the University of Guelph's 2022 study of 16 repair visits, technicians looked through customer data in six, copied data to an external device in two, and three of them tried to cover their tracks by clearing the recent files lists that most people would check afterwards.
How to choose
If the laptop holds things that would do real harm if seen, such as intimate photos, client files or identity documents, move them off the machine or reset it, and accept the cost. For everything else, reducing exposure and keeping a record usually gives you most of the protection for a fraction of the effort. The two approaches also work together: a reset laptop with a record running tells you whether anyone tried.
A sensible middle path
- 01
Back up, and check the backup opens
Repairs sometimes reimage the drive. Open a few files from the backup before you hand the laptop over.
- 02
Move out what would do real harm
Photos, identity documents and client files go to an external drive or an encrypted folder you keep with you.
- 03
Sign out of everything that syncs
Browsers, password managers, cloud drives and messaging apps. A signed in session needs no password to use.
- 04
Give the technician their own account
A separate Windows account keeps routine work away from your profile.
- 05
Keep a record of the service window
The only step that has to be set up before the laptop leaves. A record cannot be created afterwards.
Rashnova is a free way to keep that record on Windows. Before the handover you start Repair Mode; when the laptop comes back you get a report of what was opened, copied, renamed and deleted, which programs ran, and every USB device plugged in with every file copied to it, ending in a verdict. It works alongside any of the options above. It does not stop anyone from doing anything, and it only covers time when it was running.
