Most of us like to see our files in alphabetical order when we open Windows Explorer. Sometimes you may open Explorer and see that you files are not in alphabetical order. So you go ahead and set them to be viewed in order and close Explorer. Then when you come back again they are no longer in order. Windows is supposed to remember your folder view settings so when you close and re-open Windows Explorer they will be the same as the last time you had it open
There is a method Microsoft recommends to fix this problem. To do so, perform the following steps exactly as described:
Open Windows Explorer
Click on your C: drive in the left window
Click on the View menu then pick details
Sort your files alphabetically by clicking on the Name column
Hold down the Ctrl key and close Explorer
Restart your computer.
