+## Lost internet access after a TemplateVM update ##
+
+In earlier versions of Qubes, there were situations where qubes lost internet access after a TemplateVM update. The following fix should be applied in recent versions of Qubes. 
+
+Run `systemctl enable NetworkManager-dispatcher.service` in the TemplateVM upon which your NetVM is based. 
+You may have to reboot afterward for the change to take effect. 
+(Note: This is an upstream problem. See [this Redhat ticket](https://bugzilla.redhat.com/show_bug.cgi?id=974811)). 
+For details, see the qubes-users mailing list threads [here](https://groups.google.com/d/topic/qubes-users/xPLGsAJiDW4/discussion) and [here](https://groups.google.com/d/topic/qubes-users/uN9G8hjKrGI/discussion).)
+
+## Windows update is stuck ##
+
+This has nothing to do with Qubes. 
+[It's a longstanding Windows bug.](https://superuser.com/questions/951960/windows-7-sp1-windows-update-stuck-checking-for-updates)
+
+## Dom0 and/or TemplateVM update stalls when updating via the GUI tool
+
+This can usually be fixed by updating via the command line.
+
+In dom0, open a terminal and run `sudo qubes-dom0-update`.
+
+In your TemplateVMs, open a terminal and run `sudo dnf upgrade`.
