Hi all,
I am Using Windows 8.1 (Update 1). Whenever I connect My android Mobile to USB and activate USB tethering, the Whole taskbar becomes slow and lagging. Though I can click them, it takes 5-10 Seconds to Switch to other programs.However alt+tab switches to other program with ease. Pressing Start also is lagging. I Cant Click taskbar notification icons also. All these lagging stop as soon as I turn off my USB tethering. I Cant use wifi hotspot also as its connection drops every 10 Minutes or so. I am sure the problem is cause by Windows OS only, because I restored my windows 8 Backup and USB tethering works without any problem.
