Windows 10: How to undo a Orphaned Account

So today I made a huge mistake, I searched on google on how to change my username and I opened run and I did "control userpasswords2" I messaged a windows advisor and he told me that I had an "Orphaned account". He told me to do a system restore but I cannot open control panel or
search

as it says " No mapping between account names and security IDs" this is not a work computer so please help me in this confusing situation!
