Recovery passworg for CISCO hardware

[algudshopper]

It needs help for a not reset, but a password recovery for Cisco 1921/K9+CON-SNT and ws-c2960-24tc-s v08 switch.
How can I do this without losing the hardware settings?
I don't have any real experience with this.
I sent serial numbers to support, but they replied that it is no longer supported in this format.
In general, is it possible to send serial numbers or other information and get data to recover the password without resetting all settings?

Is password-recovery disabled?

Hello. How can I find out if I don't have access to the controls?

Console into the switch and post the entire boot-up process.

Hi! ..and now there really is hardware where password recovery was disabled....

Are there any options other than resetting to default? 

Thanks in advance

Depending on the IOS version, if password-recovery is disabled, successful attempt will erase the config of the platform.
