They worked perfectly fine till the late 1900 versions of win10 started rocking the boat.... and now with the 2000 versions they started performing as if they are p4's..... "underpowered" is relative.
The hardware is fine..... the software is the problem. The obvious bug caused by some genius forgetting HDD's still exist is the problem.
Windows 1909 is 2019, so those are probably 5 year devices I would guess, running under-powered spinners.
Disable superfetch/sysmain (it was renamed to the latter, no clue what Windows version you're running).
I'd rather they enable the extra features that improve the QoL of using the system, based on your post, you're running 5400RPM mobile HDD's, they're not going to perform well no matter what you do.
Other than stuff like java and vc+.... nope.
I started noticing the same problem universally as they updated to newer win10 versions. Each feature update made it progressively worse.
Doubtful.
Most of the files are not in user files or in program files.... it's win10 confiscating space.
I suspect system restore has a lot to do with that.... and if I move to SSD's I need to disable that anyway.
Nope.
I am guessing your drives are also low on space, keep at least 50-100GB free.
And there is another problem with SDD's.... the drive lifetime drops once you fill more than 50% of it.... or has that been actually fixed rather than just mitigated by now?
Just no, has nothing really to do with percentage filled, it's how much write you do, and modern drives are going to last a very, very long time, you're talking about tens to hundreds of TB written for a 250GB SSD, it's going to take a very long time to exhaust that flash.
But none of this actually answers the question..... WHY had HDD's become obsolete while no one was looking?
Is M$ simply trying to ignore older generation hardware the way they are surprised that so many people don't have TPM's? Are they hoping the older stuff will just magically poof away?
Because HDD's are slow. SSD has entered mainstream for ~7 years, and is basically on any medium range device since 2016 or so.
HDD's haven't been good for a very, very long time, they've been delaged to cheap, large storage, and that's where they'll stay.
I'm done with this thread, one cannot fix general, and you refuse to provide information as to the specs of the device, and reading between the lines these devices are all underpowered laptops with HDD from 5+ years ago.
