Quick answer
PuTTY -cleanup can remove more than one saved session, including local configuration and cached host-key information. Use it only for a deliberate local reset with a recovery plan.
Applies to
For PuTTY on your own Windows computer and an account with authorized SSH access. Use the hosting service's assigned hostname, port and user. An ordinary cPanel account is not a root login; your service may use a nonstandard SSH port.
Steps
- Identify the saved sessions and trusted host-key records you need to retain. Prefer deleting one obsolete saved session when that meets the need.
- Close active work and review the current official PuTTY cleanup documentation. Run the intended official executable with -cleanup only when you want that broader local reset.
- Read the confirmation before proceeding. Keep the correct server settings available for future connections.
Check the result
Confirm the intended local settings were removed. Verify server fingerprints again through a trusted source when reconnecting.
Troubleshooting and support
This does not remove files on the server. If you did not intend a broad reset, cancel the prompt and use the narrower saved-session control.
If the problem continues, contact support from the account that owns the service. Include the domain, exact error, time and time zone, tool name, and a redacted screenshot. Keep passwords, private keys, cookies and private message content out of the ticket.
