New Windows 10 update making everything slow

I also have the same issue on two PCs at work. Both have recently had updates installed. One is an HP desktop and the other is an Asus laptop, so on first look it doesn't seem to be a hardware issue. 

Both computers installed updates KB4497165 and KB4537572 on the 1st of March. This was about a week prior to the issue starting so it's unlikely this was the direct cause. 

My laptop has Office 2013 and the other PC is still running Office 2010, but both of them installed a bunch of updates on the 8th of March, so Sunday before I noticed the issue on my PC. The following updates were installed on my laptop: KB4022226, KB3172522, KB3039756, KB4011281, KB3114946, KB4484097, KB3039798, KB3039720, KB4464548, KB3172545, KB3178640.

The commands SFC /SCANNOW and DISM /ONLINE /CLEANUP-IMAGE /RESTOREHEALTH were literally the first thing I tried and the system is still slow. My laptop has a 4th Gen i5 with 16GB of RAM and a 512GB SATA SSD. While this is happening, the performance tab on Task Manager shows the processor barely breaking a sweat at 25%, the memory about 55% full and the disk activity mostly sitting at 0% with occasional bursts of 5%. 

I'm about to try an in-place upgrade of Windows 10. I started the process yesterday and have just arrived at the "Install" button 24 hours later. 

Is anyone else suffering from this exact issue? Is there a fix for this?

Windows 10 updates have become worse than the viruses they are meant to be stopping.

Does anybody test them? The 2020 updates have all been disastrous. What a joke.

I ended up fixing my systems. Your probably not going to like it though.  I ended up reinstalling Windows 10 Pro (Version I Own), the update that originally caused the problem was a part of the complete installation. So I didn’t have to worry about updating it after the fact.

When it was installed as a whole, it resolved my issue. Literally it was taking close to 30 minutes before I was completely logged into windows.

That all went away with a complete fresh Windows installation, as I previously stated, the update was a part of the whole installation, so once Windows 10 was installed, that was it, it runs like a champ now.

More then likely not what you or anyone's else wants to hear, I know I didn’t want to wipe my machine and reinstall, but I had tried everything I knew and it was consuming to much time. So wipe it did and a complete re-installation and now I’m happy I did it.

Good Luck, I hope you get the same good results I did.

I don't understand why everytime Microsoft has an update it is trash out of the gate and takes forever. 

I am so done with windows at this point.

New gaming computer and nothing but **** from Microsoft.

I'm buying a Mac.

So apparently Windows decided to automatically update itself while I was away from the PC. When I’m trying to log in, it takes ridiculously long (around 30-40 minutes). So I tried restarting, but startup is SUPER slow to the point that I’m stuck waiting for a black screen of death. Why is my PC slow after this recent update? 

This slowdown issue is because Microsoft has loads of useless and unwanted services running in the background. So the best long term solution is **Linux.**Yes my friend, though linux is little difficult to use but you won't face any embarrassing issues when you are in a meeting and trying to present your presentation. Linux is light weight doesn't come with any bloatwares pre-installed like the Windows OS. There are thousands of flavours of Linux distributions. you can go with Ubuntu.
