HP Windows slow to boot , black screen and then many minutes to boot up

[RosemaryNJ]

I had an update on Windows 10 and now my desktop AIO HP is extremely slow.  I tried the fix mentioned on the forum

1. http://ftp.hp.com/pub/softpaq/sp81501-82000/sp81965.exe
2. and it comes back with this is already on computer and do I want to overwrite it with answers Yes to All, Yes, No, NO to All Cancel and I tried Yes to All and it got stuck 
3. Any suggestions on what I should do next - should I disable App Readiness?
4. Thanks - have no idea why there are numbers showing before each sentence.

Measure, measure, measure.

Open the Windows "Task Manager", and switch to the "Performance" tab.

Observe the percentages for RAM & CPU & network & disk-drive usage.

Anything near 100% is not usual.

Near the bottom of that tab, click "Resource Monitor", and switch to its "Performance" tab, where you can "drill-down" to see what part of Windows is the "sore-thumb".

Or, for something completely different,    your disk-drive could be in "imminent failure" status, and thus taking 10 to 100 times as much elapsed time to do its work -- the fact of a Windows Update might have put into active usage of some "bad" spots on the disk-drive.

When I went to Task Manager which took about 30 minutes to come up, CPU 1.9%
Disk 0(C:E:) 100%
Disk 1F:0%
When I went to Resouce Monitor, I did not see a Performance tab.
Any suggestions?
Thanks

Sorry.  Instead, use the 'Overview' tab. 
But, with the disk-drive at 100%, something is really "working" the disk-drive.




As you can see in the above image, my disk-drive is essentially "idle", as it should be, for a fully-updated system.

I clicked on the 'Total (Bytes/Second)' column-heading, to sort the rows.

What do you see on your system?

[RosemaryNJ]

This is what I see but it keeps moving so can't capture it all

What I see:

CPU - 7% now; 97% Maximum

Disk - 0 Kbytes/second now, 100% Highest Active Time

Network: 1.298 Mbits/second now, 1% Network Utilization (your network adapter is capable of 100 Mbits/second, but your download speed from your ISP probably is much less)

CPU graph -- mostly "off-screen", but very low in last 60 seconds

Disk graph -- no "scale" on the axis -- cannot tell

Network -- no "scale"

is typical of an "idle" system, not an "busy" system.

Hint: click on any column-heading, to sort the rows (low to high, or click again for high to low).

Thanks for your help. Just decided to reinstall windows saving my data and now all is well. Disk at 1%. Had to reinstall Office and Norton. Just hope another Windows 10 update won’t cause this problem to come back. So nice to have my Windows 10 boot up quickly and internet surfing also is quick. I wasted so much time on this but as long as now working fine I am good. I was ready to go out and buy a new computer. Saved for now!

Yes, any "fresh" installation of Windows 10 will launch "Windows Update" as a background task, and it will take a few hours of the computer working "hard" to download & apply all the updates.  Leave it alone, and let it proceed. Restart when prompted to do so.
