Even though I pre-registered for the new Windows OS, Win 10, my current OS, Win 7 is still updating itself. it downloaded another 9 updates just last night. Jeeze, MS! bandwidth isn’t free. Your new OS rollout is only a few weeks away. Can’t you put a hold on new patches until then? There is a very high possibility that all of the existing operating systems will last that long even without new patches and all those patches will be futile in systems that are getting replaced by the new OS.
You can just archive the changes and upload them in July to any systems still using 7 by then.
