What this is, and how it's different from basic cloud sync

This is about keeping settings, passwords, clipboard content, notifications, and preferences consistent across several devices someone owns — not just files, which is its own separate category. The tricky part is that this kind of sync usually runs quietly in the background across multiple different systems (a Microsoft account, a browser, individual apps) at once, so a break in one layer can look like the whole thing failed.

It also tends to surface household- and family-level complexity that single-device problems don't — multiple people sharing devices, multiple accounts, and expectations about what should and shouldn't sync between them.

When these problems tend to show up

Why "sign out and back in everywhere" is a blunt instrument

That resets a lot of state at once, which can genuinely fix some sync problems — but it can also disrupt sync that was already working fine elsewhere, trading one problem for a new one instead of fixing the specific piece that broke.

WindowsHelper is being designed to narrow down which specific piece of the sync chain — the account, a particular app, a particular device — is actually the problem, instead of resetting everything and hoping the right thing comes back.

Common questions

Will signing out everywhere fix a sync problem?
It can, but it's a blunt approach — it can just as easily disrupt sync that was already working fine on other devices.
