Some uninstalled &quot;Pokki&quot; app hasn't cleaned up after itself. Use task manager, click on &quot;more details&quot;, navigate to the startup tab and deactivate the pokki entry there, I guess.

I have informed my client to uninstall POKKI. Hopefully he will be successful and that will solve the problem. I will advise when I know more.

Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems, with an emphasis on improving its user experience on tablets. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language, the Start screen, a new platform for developing apps with an emphasis on touchscreen input, integration with online services, support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware.
