Microsoft is interested in making as many users move to Windows 10 as possible in a short period of time. They want to capture a significant market share with the new OS and get rid of an older operating system like Windows XP which is still more popular than Windows 8. To get users to start using Windows 10, Microsoft pushed a special software via Windows Update called the "Windows 10 reservation app". It asks the user to order a free license for Windows 10 right now. If you are not happy to see such promotional notifications, here is how you can remove the Windows 10 reservation app.
The Windows 10 reservation app comes to Windows 7 and Windows 8 via Windows Update. It shows a special system tray notification icon. When the app opens, it asks you to enter your email address and this will reserve your copy of the OS, meaning Windows 10 will auto-download on your PC when it is released. Aside from that, the rest of the app gives you an overview of features in Windows 10 although it heavily uses marketing speak.
- Open the command prompt as Administrator.
- Type and execute the following command:
wusa.exe /uninstall /kb:3035583
- Reboot your PC
That's it. Now you won't have Windows 10 reservation app any more. (via Neowin).
