I’ve just lost 30mins (at least) of work. I was was in the middle of doing a complicated install of a virtual machine (I was installing FreeBSD on a QEMU virtual machine) and documenting each step. All of a sudden, a message appears from Windows 8 telling me that my computer is about to reboot in 15 minutes. There’s no way I can finish this job in 15 minutes, not carefully anyway. However, I did rush to try and managed to get to the last step (although my notes were such a mess now that I’d still would have probably had to go through the whole thing again anyway) and bang! Microsoft whammied me! It all gone. Everything I was working on GONE.
I’ve now turned off automatic updates, but what a rude and totally unacceptable practice Microsoft has imposed on us. Shame on you MS

I dont know if it just a crummy WAP or win 8 but on my system i have noticed that if i have pending updates and have not yet rebooted my wifi starts dropping out.
Hmmm. I haven’t noticed. BUt then I run Win8 as a VM on OS X, so it uses a VMware interface to the Host computer, which then uses WiFi. Win8 doesn’t know it is going through WiFi.
You can use the shutdown /a command which will abort the scheduled shutdown. I learned that the hard way lol
Thanks. Hopefully I’ll never need to use it!
