Latest on SSD settings on Win-10

Hmm, on Anniversary edition I can TRIM the drive, but that is all.

I think our posts crossed each other. How do you TRIM your SSD? manually? third party tool?

Following link includes Win-10 behavior as well, though most of the operations used Win-8.1

Why Windows 10, 8.1 and 8 defragment your SSD and how you can avoid this – Вадим Стеркин

No 3rd-party software. But actually my computer with the official build still has defragmented the RECOVERY partition. That is odd. This means we are not completely safe!

Exactly what I mentioned in an earlier post.

The problem can be avoided by checking off Recovery Partition in Optimizer. But the issue is when people have only 1 SSD drive, in which case one has to select at least one partition to enable Optimizer. Else one has to disable Optimizer completely and manually optimize as needed.

Hmm, yes, this seems to be a problem. The UI says no defragmentation nor analysis has ever run, I can not manually analyze the partitions, but the powershell script states something has been run.

On the IP computer It only did a Retrim, but no defrag.

I think this is still a work in progress for the official ring. It works halfway, but not completely.

Once Creators Update comes, we should all be safe.

Thanks for the results.

They do show that your C drive was being defragged nearly every month and that the Recovery drive has been defragged more often. This suggests to me that you might not have a spinner drive at all in this unit. Is that correct?

Yes the only device in the computer is a 32GB drive in a small laptop.

That is very OLD information, and because defragmenting an SSD is totally useless and kills the SSD, Microsoft has fixed this issue.

The information is only 2 years old (well, 26 months) and is written well after the days of Windows XP when the operating system didn't know what an SSD was.

The point is that by Dec 2014, Microsoft knew a lot more about SSDs and still decided it is worth running a defrag on occasion for performance purposes.

Have you seen anything more recent from Microsoft?

Here's how the stuff is working by default:

The default is that System Restore is turned off though (or it is in my experience)- as per the articles quoted this is part of the behaviour which means Windows runs a Defrag.

It is fixed!

If anyone is running some old build then it's that users own fault. Update to latest official (Anniversary Update) and you are safe.

I don't think that will make any difference unless someone can point me to something which says it is changed in the Anniversary build. If Microsoft have turned on Defrag for SSDs, they don't believe that anything needs "fixing" - I'd be surprised if that's changed in the 15 months since November 2015.

I thought that your script results did not find any entries. That is why I was wondering if windows ran TRIM at all.

Where did you see the Trim and Defrag?

I ran the script on my other computer, where I got these entries, but on latest IP I could not find anything.

Does your latest IP satisfy the 3 conditions that I outlined earlier?
