Alert! Upgrade to Windows 10 is back...

We have been wondering whether we should send this alert message or not, knowing that it is not totally solicited. We thought the subject matter was important enough to warn our users of our findings.You can opt-out from future communication by using the unsubscribe link below.
On several of our test computers, a new release of the root component responsible for the "Upgrade To Windows 10" eco-system, named KB3035583, has been offered through Windows Update. Here are some facts about it:
  • This version's revision number is 202.
  • Its "last revision date" is 2015 December 15.
  • It is marked "Important" so it should be pushed to your computer if you are using recommended Windows Updates settings (which you should in most cases).
But Win10wiwi tool can disable it automatically.
The good news is that the current version of Win10wiwi (the one that 99% of our users have downloaded) can disable and uninstall this component, even its newer version.
Not all our test machines have been offered the newer KB3035583 yet, but we think that it will be pushed to all Windows 7 and Windows 8 machines sooner or later (except those running Enterprise edition).
The press has been relaying rumors and facts about what is known as the "UpdateGate". We will just mention two recent articles: Official Microsoft Windows EVP blog, and a Forbes article...

It is dormant (for now)

This new KB3035583 seems to stay inactive for now: On our test systems where it has been installed, nothing new really happened: The Windows 10 icon did not show up, and no message to upgrade to Windows 10 has popped up.

We found out that it (re)installed several components that are known to run periodically, triggered by task scheduler. The related tasks are there too:
It is very likely that this new release of KB3035583 will eventually cause the set of components known as "GWX" (the internal name for "Get Windows 10") to get installed. It will also certainly reinstall if you previously disabled it, with Win10wiwi, manually, or with another tool.
See https://support.microsoft.com/en-us/kb/3035583 

In order to avoid being annoyed by "Upgrade to Windows 10" (or even have your computer being upgraded without your knowledge), you can use (or re-use) our free utility "Win10wiwi".

Users who have already run Win10wiwi in the past will usually have to run it again to disable these new GWX and KB3035583 before they activate. Win10wiwi is still available for free here:http://win10wiwi.com

Note that it is not necessary to install nor download Windows Update KB3035583 in order for Win10wiwi to disable it: If this release of KB3035583 is offered to your computer but not yet installed, Win10wiwi will disable it all together and it will not been offered to your system again.

Announcing Pro edition

We are in the process of releasing a Pro version of our utility that will automate the monitoring of undesirable Windows Update components along with improved disabling of trackers. This Pro edition will disable those components automatically, without requesting the user to run anything manually, even when Microsoft releases new undesirable components or newer versions of existing components.

This Pro version will be a paying one, yet the free version will still be available. We do not know the final price of the Pro edition yet, certainly around $10/10€.

Users who have been supporting us by contributing more than $5/5€ on our "support us" page prior to the release of Win10wiwi Pro edition will be entitled to at least one license of the pro version of Win10wiwi (one license for each $5/5€ spent on our "Support Us" page).

Support Us!

We have developed and released Win10wiwi without really thinking of a business model to fund it, beside the revenues generated by advertisements. After 2 months, we know now that these revenues are not enough to make Win10wiwi's development sustainable, so we have added a "Support Us" page to our web site in order for users to be able to support us with a contribution if they wish.
Contributions can be sent with Paypal as well as with a credit card using PlayPlug payment system. Note that some of the contributions we receive will give the contributor some benefits to Win10wiwi Pro licenses (see above).
You can also use the Support Us page and click one of the advertisements there, or an advertisement anywhere on the win10wiwi.com site. It will increase (a little) the revenue we get (and that would be good for us to be able to go on building tools such as Win10wiwi and to make them evolve, to support them... So when you think of it and when an ad seems interesting to you, please come back onwin10wiwi.com and click the ads).

Stay tuned !

  1. I just use GWX Control Panel and set my WU to Check Only download nothing. Have a running list of any WU that mention that it has to do with Windows 10 and make sure they don't get installed. No email requirement to download GWX Control Panel...and should MS change W10 for the better, a few button clicks and it's available to download.

    1. GWX Control Panel is a good tool too.
      Its approach is quite different since it just sets system settings to instruct Windows not to be upgraded.
      However, MS has in the past overwritten or ignored these settings.
      Win10wiwi also sets the same settings, and a few other ones (including the ones that control "telemetry") but most of all, it REMOVES the components involved in the upgrading to Windows 10, so that they do not have any side effect. And it prevents them from showing up again or being installed again through Windows Update subsystem.

      One of the side effects of not uninstalling the "GWX" components is that there are still some tasks that run periodically and that take resources (CPU, Memory, Disk space). Moreover, nobody is certain that there is not some hidden trigger or backdoor in said components.

      Now, GWX CP and Win10wiwi are free tools, made by people who believe that users should have as much control as possible over their systems. But MS makes it hard on us to follow all their moves. For instance, when a new version of KB3035583 is released, MS usually changes its ID, which means that even if the component was uninstalled and hidden (Win10wiwi does just that), it may be installed again. Normally, it should remain inactive, but for the side effects mentioned earlier.
      Then, to be safer, one should run Win10wiwi from time to time.
      We have an alpha version of a "pro" version that is supposed to be released some day, which monitors the available updates and does its job in the background when a "GWX" component is detected. Now putting in place the infrastructure to validate, test, support this "Pro" version, analyze each new windows update to determine if it is safe or not, is a very time and resource consuming process. And the economical balance is not easy to find. So far, Win10wiwi has costed much more than the money it made with donations and ads. The decision to go on loosing money for a "good cause" is not easy to take, especially when there are already some existing solutions that that do a part of the job...
