Windows 10 extremely slow after upgrade to version 21H1

I bought a new hard drive and installed a fresh copy of windows to test if it was LEGACY settings or was it hard drives and drivers that were previously installed on the system.

The issue went away

I have to believe that this issue is either

!: Deep in the registry

2: Previous incompatible software that is not compatible.

In my case I have found there are a large number of software bloat can interfere with speed, Drivers for Audio is a common one. 

Check your task manager as see what is eating time.  I uninstalled at least 5 drivers and bloatware that are out of date and needed to go. 

Almost all of them were Notification Services for things like Virus software, Adobe, HP etc. 

This also makes the computer safer as there are a number of issues that hackers can use to get into a computer thru some of this kind of bloatware. 

3: Legacy driver NOT compatible to the upgrade ( a little like the above but driver specific. Audio driver, Audio Device Graph Isolation, I have seen

issues from users with Lenvono Flex complain the audio driver uses 30 to 70% of the CPU usage. I uninstalled my audio driver and it still works 

so what did that driver do when it was running? That is a concern as well.

Microsoft has created a VERY complicated OS and the more complicated the easier it is to have a negative effect from outside influences.

I should not single out MS OS as most of us have heard of the Boeing disasters, Tesala issues, GPS updates etc. Seems there are issues with just about everything dependent on a CPU. The one thing they all share is human programmers. We make mistakes, assumptions and that puts thing in jeopardy.

Wired article suggested that Complex Networks are too easy to hack, that goes for software as well.

Imagine if you build a house with 2 doors and 2 windows....you only have to lock and manage access in 4 places.

Now take a house on my block 11 doors and 64 windows. I lot harder to maintain, monitor, check, lock etc.

Software is much the same and multiplied by the software you add that multiply the issue.

I am not surprised that Microsoft does not have an immediate answer because there are literally BILLIONS of combinations of hardware, software, firmware, drivers, networks and policies. A simple DNS corruption can effect millions of computers.

Sorry you are having issues, hope that this helps some.

If you have a space hard drive or maybe you could use this as a time to upgrade that hard-drive to a SSD and try a totally clean install, new drive, partitions etc. see if the problem exists....if it does then it is more than likely a driver or you may have a hardware issue that was not noticed before.

Good luck,

Any new updates regarding this issue ?

I did (again) what has been suggested my the MS people. I installed a clean copy of Windows 10. Straight out of the box, the problem still exists.

And, each Windows Update, my system gets worse.

I am not going to buy a new computer for this, or to upgrade to Windows 11 (I don't have TPM, etc). And, how would I even be sure the issue would clear itself up with the new OS ?

Thanks,

Mike

Wish it had been as simple. we run a 10G network and slow is different for us....

Feeds do not slow me down, not like this....

It took MINUTES to get File Explorer to move, to bring up a window, to open a browser.....

there is a big difference between SLOW and GALACIAL.

I have seen PAINT DRY faster.....

I blew it out and rebuilt....works perfect....SOMETHING SOMEWHERE did not like the change....

Do not have time to troubleshoot it down to the culprit but it was an issue. I suspect it is a registry setting on the local machine and not the domain GP.

Just upgraded my Surface Laptop and OTHER than bluetooth no longer sees devices (which is annoying but I can deal with it) it seems to be doing very well.

The blue tooth thing is very odd indeed. If I make the laptop discoverable I can see it from other devices and when they request to connect I get the proper responses from the laptop to connect and it works great.

BUT

If I have mouse or pen to attach to the laptop it does not see them and I cannot add them to my bluetooth connections.

Under the activities tool it says Bluetooth is not connected.

I have tried uninstalling, new drivers, etc ,etc, very odd probably a regedit issue somewhere.

I can live with it for the time being I do not have to have a bluetooth mouse and I rarely use the pens bluetooth functions anyway....

I think the slow down issue is random and related to a driver setting somewhere but the difficult thing is that it is VERY random.....

It is not like ALL DELL computers have this issue or ALL HP computers have this issue,,,,

I wonder if that is because of domain GP differences? I wonder how many of these are computers connected to a Domain?

Best of luck I wish we all had the same issue it would be easier to track down and repair.

Regarding the action of turning off "News and Interests". Because this feature was causing me some slight annoyance, a few days ago I turned it off. The notebook pc running Win 10 21H1, with 2021-08 Cumulative update KB5005033, has 2 users. It was after turning OFF "News and Interests" for both users, then rebooting the pc (next day), that the response became very slow, although I did not associate the cause and effect at the time. For several days the pc has been all but unusable, it was so slow.

Having today seen the discussion concerning "News and Interests" causing similar issues to those I was experiencing, I decided to do the reverse, and Turn ON "News and Interests". I did this with each of the 2 users of the pc, with no noticable effect. Then I shut down & restarted the pc. Immediately the pc rebooted, it was totally back to nornal. No juddering of the mouse pointer. Thunderbird, Firefox, Word & Excel starting & closing normally.

So, whatever "News and Interests" is doing, it may be just as disasterous to turn it off as to turn it on.

I have just typed this message with no problems at all, something I couldn't have done only an hour ago!!!

Microsoft, SORT THIS OUT.
