Windows 10: Everything extremely slow suddenly

My laptop was running fine up until about 2 days ago. Now it is extremely slow with everything including task manager and settings. Restarting doesn't help at all and I haven't installed anything recently. I've had malwarebytes do a full scan and it found nothing. The task manager shows that the hardware is nowhere near maxed out. Any ideas what could be causing this?

Jumplist sometimes extremely slow

I bought a new laptop with Windows 10 recently.

Only after a few days, the jump lists started to get extremely slow.

But they behave that way just for a while, then they work as they should again.

When slow, it takes several minutes for the jump list to appear. It is extremely annoying. Especially e.g. when I have opened a remote desktop and want to open another one via the jumplist.

I had exactly the same problem with my old Windows 7 PC and assumed that I would get rid of that problem,
changing both PC and OS, but no.

I do not want the standard answers to this problem:

- Disable Aero

- Clear the (Explorer) Cache for Jump lists

- etc.

It is definitely something else. I mean, how would the jump list cache get full after only a week? And why does the jump list get slow only sometimes and then suddenly works just fine again?

So please, give me an answer that takes this into consideration.

 

Hard disk suddenly extremely slow

I will assume you mean that you are talking about your new 1TB Seagate.

My workday involves plugging hard drives into workstations for data destruction. Often, I come across hard drives that have the following problems that do not raise any errors from S.M.A.R.T. tests:

1. Very slow random write speed. This could be due to internal resistance on the spinning platters or resistance on the read/write head. Read speed is about 20% percent faster than the random write speed on a normal hard drive.
   
2. Very loud metal scratching sound coming from the hard drive. I have had hard drives pass S.M.A.R.T. tests that sound like a car is dragging a metal body panel behind it.
   

Possible cause:

• Shock to your hard drive. Did you or a mail service drop it or accidently hit the drive on something? This could cause the drive to degrade rapidly.
  

Check:

• Check for programs making frequent read/write requests to the disk in activity monitor. Make sure no unwanted programs are tying up your disk in the background.
  
• If activity monitor looks OK, check how long it takes to transfer a large file to the disk. It should be close to the drive's advertised write speed (this may be affected by how the drive is connected i.e. USB 3.0 versus SATA).
  

If your disk is unable to write close to its advertised speed (or the maximum speed of the connection type) with few interruptions from other programs, it may just be faulty or damaged.

Update:

Just came across this possible solution
