I have upgraded from win 8.1 single lang. operating system to win 10 last year(in 2014). Everything was perfectly fine until few days back. When I installed an app from HP (HP LoadRunner 9.0) on my Lenovo laptop, my laptop started behaving in a very unusual manner.
For example, Start Menu icon, Notification Icon(just beside Speakers icon in System Tray) became non-responsive. Moreover, lenovo app Shareit also became non-responsive. So I uninstalled the HP softwares/apps which I installed few days back. Unfortunately, even then also the problem still persists. What should I do now? Please, help me somebody.
