Hi, As 8.1 is now pretty much installed to all those who have opted for it via MS store. I have noticed that the WEI tool is no longer available via system properties. As a consequence of this my SSD was not recognised correctly and upon running a maintenance cycle a de fragmentation session was started upon what the OS thought was a mechanical drive . I remember reading that the OS runs WEI to determine what disk you have by how fast the Read/writes are and when the R/W are over a certain speed it then detects the SSD correctly. Anyway to cut a long story short you have to run the assessment tool manually via the cmd line. The cmd for the assesment tool is Open a CMD (elevated admin) right click start button (win 8.1) choose command promt(admin) and a cmd box opens. with the file path C:\Windows\system32 type "winsat formal -restart" without the quotes and let it do its full assessment. then your SSD will be recognised correctly and not be defragmented. Hope this helps. Deck
Running it through the command prompt is the only way as Microsoft has removed it from the control panel. They have stated that in the years it was implemented it was never used properly, and the average person didn't even know what it was.
Mine ran automatically I guess cause i can see the lowest score in the game explorer (needs launch day patches for it to show tho)
I have both and when I checked Windows defrager it was already set to trim. I now ran this winsat just in case
