portability and "sensitive" files

[Admin]

so let's continue on this complex issue of portability and syncing, which would require a thesis in order to understand..

anyway, I delivered my windows 10 pc and
since some days I have both pc's side-by-side and
every day I'm transferring/syncing both pc's (with my home laptop),
with these files excluded:

Code:

<Item>\PortableApps\CentBrowserPortable\User Data\*\Cookies*</Item>
<Item>\PortableApps\CentBrowserPortable\User Data\*\Extension Cookies*</Item>
<Item>\PortableApps\CentBrowserPortable\User Data\*\Login Data*</Item>
<Item>\PortableApps\CentBrowserPortable\User Data\*\Preferences</Item>
<Item>\PortableApps\CentBrowserPortable\User Data\*\Secure Preferences</Item>
<Item>\PortableApps\CentBrowserPortable\User Data\*\Sync Data</Item>
<Item>\PortableApps\CentBrowserPortable\User Data\*\Web Data*</Item>

windows 10 cent worked almost instantly, I only had to login once I think,

well, almost every day, if not every day, I had to login to the windows 7 cent,
while in windows 10 it was working smoothly every day without having to login anywhere!!

also, I changed the whole hardware for both pc's (i.e. I swapped them) today and
here's what happened:
win10 required a login and many cookies broke!
win7 worked without any intervention!

so the subject of portability and syncing when it comes to chrome and chromium is
interesting, full of surprises and it needs investigation
(while it's too boring in firefox, because it works no matter what, from where, etc)

Only Google sync was broken, or all your login websites(for example, this forum) were broken?
