I just found bug with my OneDrive Folder on my User folder, every time I turn on the computer after sometime the OneDrive folder change to SkyDrive folder and the blue cloud Icon of the folder gone the items still there and work and after the computer restart it back to normal and after 1-2 hours it back again even if I do not use the computer.
Moreover I did not use my computer for 2 month and before this 2 month I did not have this problem.
