Migrating a Chrome profile to another computer

Cookies and passwords are encrypted with DPAPI. Boo! This makes things difficult and annoying.

See https://sourceforge.net/p/keepass/wiki/Recover%20Windows%20User%20Account%20Credentials/ and https://old.reddit.com/r/vivaldibrowser/comments/65qrlb/importing_cookiespasswords_from_vivaldichrome/

1. Copy %LocalAppData%\Google\Chrome\User Data to the new computer
2. Export HKEY_CURRENT_USER\Software\Google\Chrome\PreferenceMACs using regedit

You can stop here but only bookmarks and some other stuff will be transferred (untested)

1. Enable “Show hidden files […]” and disable “Hide protected operating system files” in Windows Explorer if not already done
2. Copy the SID folder to the new PC (folder called “S-1-5-[…]”)
3. Download dpapi_migration.reg and edit <SID> and <username> to match the old PC account, then apply it.
4. Run dpapimig.exe in cmd/powershell and enter old password if required.
5. Done!

Now you should be able to delete the copied SID folder and open Chrome.
