I wouldn't normally do this however, this may affect a significant number of our members data usage in August if you connect your PC's to the internet through a WiFi router (WiFi Ranger, Wave, etc) or connect to your mobile hotspot over wifi:
On August 2nd windows 10 Anniversary update begins. It is projected to be a very large automatic download.
To manage this download I would suggest that you mark your cellular WiFi network as "metered" on your Windows 10 laptop or PC. Here is how:
go into the Settings Menu > select Network & Internet > WiFi > Advanced Options.
Next on each cellular WiFi network toggle Metered Connection to ON This change allows you to control when the update will be performed.
When you are ready to do the update (connected to a high speed Wifi network that is not metered) go to Settings > Windows Update > and select Download
There is a second feature you should consider disabling while you are on the road:
Internet Peer-To-Peer - feature shares your data connections with others to speed downloads
to disable the feature go to Settings > Update & Security > Windows Update > Advanced Options > under Choose How Updates Are Installed turn off Update From More Than One Place.
