Choose the least disruptive action
A restart, update and reset are not interchangeable. Each has a different purpose, risk and recovery requirement. The right choice depends on what you know, the value of the data, the impact of downtime and whether the device or account may be unsafe.
Restart after saving work when a simple temporary fault is plausible. Update from an official source after checking storage, power and backups. Treat a reset as a last resort after confirming you can recover data and access. Seek official or qualified support when the problem is high-impact, security-sensitive, physical, repeated or beyond your confidence.
Compare the decision, not the button label
| Option | When it can be reasonable | Before you act |
|---|---|---|
| Restart | A stable device or app behaves unexpectedly and open work can be saved. | Record the symptom, save work and know whether a restart loses important evidence. |
| Official update | The provider documents a relevant fix or the device needs supported security updates. | Back up important data; check power, storage, connection and any work-system rules. |
| Reset or reinstall | Lower-risk actions have failed and there is a verified recovery plan. | Confirm backup restore, account credentials, licence or activation details and the exact scope of deletion. |
| Official or qualified support | There is safety, security, data, warranty, access-control or repeated-failure risk. | Provide the evidence, impact and test history through a known genuine support route. |
Use a reset only with a recovery plan
- Confirm exactly what the action resets: one app, a setting group, a user profile or the whole device.
- Verify that the backup exists and can be accessed. A backup is not useful if you cannot sign in or restore the needed files.
- List the accounts, multi-factor method, recovery contacts, licences and services needed after the action.
- Check whether the device is managed by an employer, school or organisation and use its authorised support process.
- Keep the evidence and record the decision, especially if the problem returns after the reset.
Updates belong in a recovery-minded routine
The NCSC notes that current software includes security patches, and recommends backups before updating. Follow the device’s current official instructions rather than a generic workaround; see keeping devices and software up to date.
Recovery-action FAQs
Will an update erase my files?
Routine updates normally aim to preserve personal data, but any change can fail or reveal an existing problem. Back up important data, use a stable power source and follow the official instructions for your specific device.
Should I reset an account if I cannot sign in?
Use the provider’s official recovery process first. A password reset can be appropriate, but do not repeatedly guess, share verification codes or follow links in unexpected messages.
What is qualified support?
It is a known official provider, authorised repairer, trusted internal IT team or a competent professional appropriate to the device and risk. Verify the contact details independently before sharing access or information.
Choose the next safe step
Use the guide that matches the evidence you have, the impact of the problem and the reversibility of the next action. Do not rush from uncertainty to an irreversible change.
