Hi,
Thank you for posting in Microsoft Communities.
Some users received this update, who are participating windows10 insider program.
If you don’t want to receive this kind of updates, please log out from the insider program.
Microsoft will offer a free upgrade to Windows 10 for qualified new or existing Windows 7, Windows 8.1 and Windows Phone 8.1 devices that upgrade in the first year! And even better: once a qualified Windows device is upgraded to Windows 10, Microsoft will continue to keep it up to date for the supported lifetime of the device, keeping it more secure, and introducing new features and functionality over time – for no additional charge.
If you don’t want this upgrade, hide the particular windows update (KB3035583).
Please follow the below steps to hide an update.
- Open the Control Panel (icons view), and click/tap on the Windows Update icon.
- After Windows Updates or you check for updates, click/tap on the .....update(s) is available link.
- Right click or press and hold on a listed Windows Update that you want to hide, then click/tap on Hide Update.
- If prompted by UAC, then click/tap on Yes or enter the administrator's password.
- You will now notice that the now hidden Windows Update is grayed out. Repeat steps 3 and 4 to hide another Windows Update. When done, click/tap on OK.
Hope it helps.
