On 29 July Microsoft's free upgrade offer is due to end, but we're all waiting to see if that actually happens. If it does, those Windows 10 upgrade notifications might cease. But of course they won't: Microsoft will simply want to you pay to upgrade after 29 July 2016. Fear not, though as there are a few ways you can disable the upgrade and stay on Windows 7 or 8 forever. We won't go into all the reasons why you might not want to upgrade: those are covered in our Should I upgrade to Windows 10? feature.
Note: If you have already ended up with Windows 10 against your will, here's how you might be able to downgrade again to Windows 7 or 8.1. In essence, you have 30 days after the upgrade to roll back to your previous OS.
Update June 2016: Back in May we heard reports of the GWX box changing its behaviour (including from our sister title PC World, from which we sourced the image below). Now, it seems that clicking the 'X' to dismiss the box is taken as your consent for the upgrade to go ahead. For the past six months or so, it was the only way to exit the dialogue box without agreeing to the upgrade (the two prominent buttons were "Upgrade Now" and "Upgrade Later". With the redesigned GWX interface, you now see a scheduled date and time when the upgrade will take place and you have to find the tiny link for rescheduling or cancelling the upgrade. The exact wording is "Click here to change upgrade schedule or cancel upgrade schedule", and the link is only on the word 'here'.
At the end of May, Microsoft reportedly backtracked on this underhand behaviour, and told the BBC: "We've added another notification that confirms the time of the scheduled upgrade and provides the customer an additional opportunity for cancelling or rescheduling the upgrade."
More recently, and in the light of a Seattle woman successfully suing Microsoft $10,000 for disruption caused by forcibly installing Windows 10 on her machine, the company has now said it will look again at making the process less confusing.Terry Myerson, executive vice president, Windows and Devices Group, said: "The new experience has clearer options to upgrade now, choose a time, or decline the free offer."
How to stay on Windows 7 & 8 forever: Never10
As you'll see below, there are a few other methods which have all worked for a period of time, but some users have said they no longer work. Never10 is the latest tool we're aware of that can disable the upgrade. It's free, and doesn't require installation. You simply click a button and the necessary changes are made to your PC. There's also a button which can remove any downloaded Windows 10 installation files which could be hogging up to 6.5GB of your hard drive space.
You can also use it to re-enable the upgrade should you ever change your mind, so it's not really "never". But then again, you're not actually going to run Windows 7 or 8 "forever", either.
Do let us know in the comments below if Never10 works for you.
How to stay on Windows 7 & 8 forever: GWX Control Panel
Never10 should work, but in case it doesn't you can try GWX Control Panel (which doesn't require installation). This does much the same thing, but has a few more buttons to click. The latest version is 1.7.4 and was posted at the end of March 2016.
How to stay on Windows 7 & 8 forever: GWX.exe and the KB3035583 update
Here's a bit of background information which may help in your quest to stop the notifications.
The Windows Update responsible for the white logo in your Notification area (shown above) is KB3035583 and you can check if your PC has installed this by heading to Control Panel and then Windows Update. Then click on 'View Update History'. From here you'll see a new window pop-up and you'll be able to see a link to 'Installed Updates'. Click on this and it will open another tab with all your previously installed updates. Give the window a few minutes to load and at the top right-hand corner search for KB3035583:
Right click on the update and select 'Uninstall' and follow the on-screen prompts until you are asked to 'Restart Now'.
Upon restarting the PC, go back into Windows Update and 'Check for updates', you should now be able to see KB3035583 as an optional or recommended/important update. Right click on the update and 'Hide update'. Sometimes you might see 'Upgrade to Windows 10, version 1511, 10586' (this was the latest build in February 2016), alternatively it might just appear as 'Upgrade to Windows 10', if you see these updates too, right click on them too and hide them.
Finally, restart the PC once more and the icon should have vanished.
Windows 7 and 8 are still supported by Microsoft
Recently there has been a lot of confusion about when Windows 7 will cease to be supported. The table below should clear this up: Windows 7 will be supported until 2020, and Windows 8 until 2023. You must have the specified updates or service packs installed, though.
