I have a laptop that dual boots Windows 7 an 10 from different hard drives (there are 2 hard drives in the laptop and I switch boot device via BIOS). Neither OS is on the domain.

If I boot into Windows 10 and try to access folder "C:\Users\Joe7" on Windows 7 drive I get this message:

You don't currently have permission to access this folder

Click Continue to permanently get access to this folder"

I understand why I get this message (accounts have different SID-s) and if I click "Continue" I will gain access.

My question is: what are the implications for Windows 7 user "Joe7" (or any other Windows 7 users) when laptop is booted into Windows 7 again?

    Changing the permissions on a user's profile directory isn't a very good idea. If you want to share the data, transfer the data to a directory that is owned by Everyone, this will allow both installations access to the data and prevent profile corruption. – Ramhound Oct 3 '19 at 22:15
