If you're like me and have just installed Windows 10 Insiders Preview build #10130 and are having problems with it, you may want to return to your previous build.
Windows 10 allows you to return to your previous build.
Go to the Windows Update screen (WIN+S, Windows Update) in Settings and click on the Recovery link in the left side bar.
In that screen, click on the Get Started button below "Go back to a previous version of Windows" and follow the steps.
Good luck!
