This is an ongoing discussion in other forums. All the folders in the first picture, are apparently generated by Windows Live, on useage. They do not appear to have any use. I delete mine during weekly maintenance. But if you are unhappy with that step, why not transfer them to another place and see if there is any effect on your computer - I doubt it. I would say they are more of a visual nuisance.As they are taking up zero space
The second folder should be left alone as it is operational.
The first has been filed as a bug but, fwiw, on the default settings in Windows explorer, you would not even see these hidden folders, so I imagine MS regard it as privately owned, for right or wrong! ,
