Windows 10: I don't want to use shared account for my computer, how do I switch?

I bought a new computer. I mistakenly signed in using my old shared account. I want to use Microsoft 365 with the subscription I bought for my new computer, and log out of my shared account. I can only use the downloaded key I bought from Amazon one time, and I can't get Microsoft 365 onto this computer. I can only save on the OneDrive, and I want to be able to save documents directly onto my new computer. Please help me register with my own account information and not with my shared account information.

Cannot access shared network drive

I could scream! so much time wasted on this stupid error, as if time is not precious enough!
It probably would work fine if I could see the other computer! But I cannot see the other computer!

 

Cannot access shared network drive


Personally, I wouldnt use Everyone. If anyone hacks into you, they have full access to everything and can demolish everything on your raid. I would rather set up accounts and access separately for each person. That way, I know who did all that damage. In the end with a little extra work, I feel more secure by using Authenticated Users.


If this helps.
step 1 create non-microsoft account and without email and address without admin rights
step 2 share a drive or folder to specific user account (if Everyone is listed, remove it)
step 3 set security > add Authenticated Users (if more than 1 account) or add specific users
step 3a remove Everyone from list
step 3b uncheck full control and write for all items listed except SYSTEM and Admin account.
step 4 right click Start > Computer Management > System Tools > Shared Folders > Shares ... to verify settings and change anything else. You can also see the number of connections to each share here.

 

Switching Accounts

The easiest way I found (Noting the limitations of WMail)
is copy and paste into a new mail from the address you want.
Or forwarding the mail to that address and replying from there.
Doesn't always work though.
