I upgraded three Windows 8 computers to Windows 8.1. One computer of three has the SkyDrive Sync Engine Host high CPU usage problem. Later, I upgraded those Windows 8.1 computers to Windows 8.1 Update 1. The one computer still has the problem.
Thanks for RACoutu's method. Finally, my SkyDrive/OneDrive tray icon doesn't flicker continuously on one of my computers.
In fact, I used RACoutu's method and failed several times. Maybe I didn't follow the steps exactly that times.
I remember something about my final successful try:
- Perform RACoutu's method. Notice, please end all OneDrive processes by Task Manager before delete the OneDrive setting folder. Then, rebooting computer at this time could be useful.
- I moved my OneDrive location by: File Explorer/left pane/right click OneDrive/Properties/Location/Move...
The original location of my OneDrive is D:\OneDrive.
I moved it to D:\a\OneDrive.
And then I moved it back to D:\OneDrive.
The flicker problem is solved for my computer.
Good luck.
