Windows 10 in a Surface Pro 2

Downloaded Windows Movie Maker to which I am new.  Initial issue was the acceptance of appropriate file extension. Imported files from camera .mov so converted to .wmv allowing move to 'collection' pane.

Like the experience of many others, Preview Screen remains black but sound unaffected.

Checked for driver updates via dxdiag and Intel Graphics driver appears current, though cautionary message when checking Intel suggested downloading Intel generic drivers might create technical issues so I am reluctant to make any changes.

Is there a solution or the prospect that Microsoft will issue an update to correct this widely experienced problem avoiding the need to use an alternative editor?
