I am running Windows 8.1 Single Language for about a year now and although Windows 10 is due to release tomorrow, I've decided to put things on hold for a while and stick to Windows 8.1.

So I canceled my reservation for Windows 10 through the "Get Windows 10" app but something unusual happened today. I've noticed some network activity that consumed quite a bit of bandwidth. I narrowed it down to a Windows Update which has failed to install. Turns out it was named "Upgrade to Windows 10 Home Single Language". Here is a screenshot from the reliability monitor:

enter image description here

This download consumed almost 2.5GB before it failed to install. But now it has started downloading again. What do i do?

  • What are your Windows Update settings? Do you have it set to automatically install Windows Updates, or download them for you and choose to install yourself, or not do anything at all? – MC10 Jul 28 '15 at 12:56
  • I've set it to install update automatically, but I don't see a Windows 10 upgrade in the list. – Ashwin Jul 28 '15 at 12:58
  • Try changing that and see if it still starts downloading itself. – MC10 Jul 28 '15 at 12:58
  • It might take a while to check if it starts downloading automatically. – Ashwin Jul 28 '15 at 13:00
  • Installation Failure: Windows failed to install the following update with error 0x80070001: Upgrade to Windows 10 Home Single Language. – Ashwin Jul 28 '15 at 13:12

You should remove the upgrade agent if you want to prevent it from downloading the upgrade:


Note that the instructions refer to the "nag" icon but that is just one component of the background system - you should use option 2:

Remove Windows Nag Icon To Upgrade To Windows 10

Microsoft has pushed out a nag tray icon, that never goes away and you cant close it, trying to get people to upgrade to Windows 10.

While it is fine to offer something like that, the point that you cant get rid of it or close it, is what the problem is and shows how desperate Microsoft is to get their piece of the App Store pie that Apple and Google enjoy.

Option 1: One way to get rid of this nag ware is to remove the update that installed it. You must uninstall KB3035583.

"To do this, launch Control Panel, click on Programs > Programs and Features, and in the left side of the screen hit the “View installed updates” section.

Look for KB3035583 in the list, right-click it and hit the remove option. If you don’t want to be bothered again in the future, just hide it and no other notifications will be displayed because the update won’t be installed again on your PC."

Option 2. There have even been others who have found it goes even deeper than that.

"After you uninstall KB3021917, KB3035583 and KB3022345, you also need to disable two tasks in Task Scheduler.

There are two tasks under TaskScheduler > Task Scheduler Library > Microsoft > Windows > Application Experience, "Microsoft Compatibility Appraiser" and "ProgramDataUpdater", that will continue to contact telemetry servers even if telemetry is disabled. These tasks run and phone home even if CEIP is opted-out of. Reproduce (on Win7 Pro)"

Option 3. Simple .bat file script

But if you are a tech and have a lot of computers you now need to remove this from, then going to each machine and removing it, rebooting, then hiding it from the updates is going to be a pain, even if you write a script for it.

To avoid a reboot you can simply stop the exe that is running the tray icon, rename it the folder and be done. I have made a bat file to do this for you, just make sure to run it as administrator of course.

  • @qasdfdsaq Would this disable the upgrade even for the future? As I plan to install some months later. – Ashwin Jul 28 '15 at 13:30

    @Ashwin: You do not need the agent to upgrade in future, it is only there to provide the nag icon and pre-load. You can upgrade manually at any time, it just won't auto-download the upgrade for you. – qasdfdsaq Jul 28 '15 at 13:37

    I just wanted to stop the silent download, never asked for removing the Get Windows app. How could this be considered a duplicate as the original is radically different from what I have asked. Anyway @ qasdfdsaq , I have tried out step 2 and now the Windows Update windows doesn't open. Re-enabled and it worked. – Ashwin Jul 28 '15 at 14:02

The upgrade continues to show up as different KB patches.

The BEST (official) way to prevent the upgrade adviser from running is the following:

To block the upgrade to Windows 10 through Windows Update, added the following registry key/value:

Subkey: HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
DWORD value: DisableOSUpgrade = 1
