Here is the scenario. You are working away in Windows 8.1 and want to save a document to SkyDrive. You look for the SkyDrive link in Windows Explorer but it is not there.
Don’t panic; your documents are most likely fine and you can get to them in the web browser via http://skydrive.live.com

The solution is to open a command prompt (press Start button and type command) and then type:
and press Enter. You don’t need to run the command prompt with administrator rights.
All going well, SkyDrive will reappear:
What if it doesn’t? Now you have to check the logs or event viewer and look for specific errors. But the simple technique described first has always worked for me.
