Microsoft has taken a persistent approach to convincing its users to upgrade to Windows 10. The company recently incorporated full-screen pop-up notifications to Windows 7 and Windows 8.1.

The “Sorry to interrupt” notification fills up the whole screen and gives users a number of options, such as selecting to upgrade at once or be reminded at a later time, having the pop-up reemerge every three days.

Users can also view two other options that can be accessed using the smaller links on the left. Through these, the user can choose to receive the notification three more times or never to be alerted again.

The pop-up notification gives a warning to users that the upgrade period for Windows 10 will be free of charge only until July 29. After this date, Microsoft is set to charge a fee for the installation of Windows 10, developing the newest step in the company’s efforts to convince its users to switch from Windows 7 (from the last six years) and Windows 8.1 (from the last two years).

The technology company has been more than eager in its campaign to persuade and assure its users to upgrade, recently having to deal with a $10,000 bill for a messed-up, unsought Windows 10 upgrade.

Microsoft has then confirmed its efforts to modify its recent pop-up notification that was programmed to install Windows 10 when a user tries to cancel using the ‘X’ mark on the screen’s top-right corner.

It has then resulted to a new pop-up notification that takes up one’s whole screen; it is yet to be determined whether users will deem it as either more useful or less frustrating.

According to the Guardian, it is possible that users might unintentionally press the ‘Upgrade now’ option without realizing it depending on the dialog box that Microsoft uses.

Meanwhile, users with the latest Windows version will not get to experience the new notification for having the Windows 10 installed. Other computers that will not have the latest pop-up include those that have been detected as incompatible with such OS, have previously tried to install Windows 10 or have opted to roll back to previous Windows versions.

As stated in the support document for the latest notification, any user who has chosen to disable the Windows 10 upgrade or the company’s previous offers by modifying registry key settings will not see the new pop-up anymore.

Users choosing to alter the registry and put a stop to Microsoft’s notifications have not been a positive sign. Previous upgrade notifications from the company have already interrupted weather forecast and pro-gamer streaming, among others.

Windows 10 was first released on July 29, 2015 as a free upgrade; with its free upgrade ending on July 29, its Anniversary Update is also expected to launch on Aug. 2.
