Duplicate SIDs

[boblc123]

Hello. I used FlyBy11 to upgrade from Windows 10 to 11 on 2 separate computers. Both computers ended up with the same SID which broke my file sharing between the 2 PCs. Can someone tell me if Flyby11 caused the duplicate SIDs or if something with my upgrade process caused it? I downloaded Flyby11 on PC1. Launched the tool and used the tool to download a Windows 11 ISO. I then copied the Flyby11 tool AND the Windows 11 ISO over to PC2 and upgraded both computers at the same time. Did copying the same ISO over cause the duplicate SIDs or is there something inside of FlyBy11 that caused this?
