In Windows 10 Home:
Goto Settings, Accounts, Your info.
Click on "Sign in with a local account instead" and follow the instructions from thereon.
As we discussed, that will only make me literally sign in with a local account, but it will not change the folder name
from
C:/Users/skype
to
C:/Users/Owner
Changing this folder name is critical because I want to sync dropbox, using the same folder structure as my main computer. (Please see our discussions above for reminder) But it seemed impossible, so that was the whole point of factory reset, as
@patcooke suggested me. (Please see our discussions above for reminder)
So
@Neemobeer said "If you open a command prompt and just type
set and look for userprofile. It may just point to the Skype user directory. "
So I checked, and as he said, it did show that the userprofile still pointed to Skype user directory.
"Sign in with a local account instead" does not solve this problem.
I have to make userprofile to point to a directory of my own choosing.
