I upgraded to 8.1 and everything is fine, apart from these 2 issues: -
1. If I start a maintenance run manually via Control Panel, Windows will start defragging my SSD, which obviously shouldn't happen. You can see it happening here, even though the drive is correctly identified as an SSD: -
I believe this bug was an issue in Windows 8 as well.
2. The System Reserved partition shows up in Optimise Drives, as it did in Windows 8, but I am unable to optimise it. If I select it and click the Optimise button, the Optimise Drives window disappears, reappears, but nothing has happened. It still says "Never run" and "Needs optimisation" next to it. Also, that causes an error to show up in Event Viewer each time I try it, as you can see here: -
The error is the same each time: -
Also in that list of logged events you can see where events have been logged saying that my C drive has been defragmented and not just retrimmed.The volume System Reserved was not optimised because an error was encountered: The parameter is incorrect (0x80070057)
I have tried running chkdsk on the drive. I've tried running System File Checker. I have tried this command: -
DISM.exe /Online /Cleanup-image /Scanhealth
Everything checks out fine and there are no errors.
Is this something I should be concerned about? Issue 1 only occurs if you manually start a maintenance run from Control Panel and it appears to be a bug in Windows, but that's easily solved by just letting maintenance run automatically on a schedule. It's issue 2 that I'm more concerned about. My system is running great and I don't know if not optimising that small 350 MB System Reserved partition really matters.
