After three frustrating days I’ve decided to seek assistance…
Current problems:
-
[*]Lag of 5-10sec between mouse click and action (mouse/cursor movement remains normal)
[*]Pop-up windows are either white (a mouse-over often reveals the content) or completely clear showing desktop (mouse-over has no effect).
These problems disappear when system is restarted or I sign-out and sign-in, but reappear a little later (often when I’m away from the PC).
PC:
Custom-built (Asus Z170-Deluxe mobo, 32GB mem, Intel i7-6700K 4.0GHz, 2xSSDs, 2xHDDs) running Win 10 Pro (from new, not an upgrade) ver 1511 build 10586.633
Recent History:
A few days ago I had problems with the Start Button, Task Bar and System Tray that would disappear after a system restart:
-
[*]Many minutes after a restart icons in the Task Bar lost most right-click functionality (i.e. the pinned and recent lists), the Start Button lost left-click function (& the keyboard Start button too). The Action Centre icon turned white showing a message waiting but wouldn’t open.
[*]Reliability Monitor confirms the system OK until 12th Oct. when its graph plummets. There’s a long list of critical failures, Windows Shell Experience Host and System Settings Broker were the first two that “Stopped Working” followed by some of my applications and Cortana which “Stopped responding and was closed”.
[*]Earlier that day, there had been Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3192441) plus Store update so I rolled back the system to the 11th. This had no effect so I rolled back to the previous restore point on the 6th Oct, then the Start Button, Task Bar and System Tray problem ceased.
However, a day later the current time-lag and empty window problem started. The only updates between 6th and 11th Oct (apart from Windows Defender definitions) were .Net Runtime Package 1.4 and .Net Native Framework Package 1.2.23205.0 Surprisingly, Win10 didn’t create a restart point before these updates. Is it advisable to remove these packages, if so how?
