I've reserved the Windows 10 upgrade on my tablet PC (running Win 7). Yesterday Microsoft has started distributing it — though not to everyone at once — saying users will be notified when it's available on their computer "in the coming days or weeks".
I'm not in a hurry, but I'd like to know how I can tell when it's my turn. What are the cues that tell me my computer has started downloading it?
(Other than monitoring network traffic, I mean. Perhaps some file or folder that's created, or some entry in some kind of update log?)
I've already tried running
wuauclt.exe/updatenow in an Administrator command prompt to force the upgrade, as suggested elsewhere on the internet, but I've seen no signs that any kind of update process has started.
