Drive with OSV is the Primary Drive containing OS, while FDV is the secondary drive. So you will need the OSV key For those dates I did some research but couldn't understand microsoft's explanation. It has something to do with Support Expiration.    Unless encryption is a business requirement for you, I would remove bit locker    
I have Windows 10. I'm walking through "SupportAssist OS Recovery" I'm being asked to provide a Bitlocker Recovery key. There are 2 keys available. Which do I choose? #1: Drive = OSV, Upload date = 7 June 2023 (yes, 2023) #2: Drive = FDV, Upload date = 9 Mar 2023 (yes) Info:  My laptop time is always correct AFAIK. First follow-up question: Should I delete one of those keys? Second follow-up question:  What do OSV and FDV stand for ? Thanks
Which Bitlocker key do I need for "SupportAssist OS Recovery" ?
