    This is an important topic to talk about because I had an issue when I configured Win 10 for the first time. The problem was that the computer showed the advice but it only had 3.8 MB of thrash! It was a new one

    I get this exact error message multiple times after going through all the steps you described. I have over 150GB free on the C: drive, and the Windows 10 update continues to provide the same error message.

    I can relate to Jeff’s comment from July 6th. I too have gone through all necessary steps to free up space in the C drive, but I am still getting the same error message multiple times. I have 336gb of free space and only used 111gb. Please help. Thanks!
