user136398: Located an old crypto address on my old laptop prior to recycling - I have no idea what exchange if any - I have a number of passwords that may be associated with it, but have no idea where to start - any suggestions?  The address / account looks like this (made a few edits).  8fe2e2e3-7f26-46ab-b181-e6831 eee36c8

The only Hexadecimal numbers with hyphens that I recall seeing are the so-called Wallet-IDs provided by custodial services to account  holders.
An example would be
Simplecoin but I'm sure there are many more. I recall blockchain.com have used Wallet-IDs with a similar form.
I can't think of any real† wallets that use Wallet-IDs of that form.
