HP Laptop boot time slowed down drastically after the latest (20H2) update.

[Ashish_Poojary]

Few days ago, I updated my HP Laptop with the feature update (20H2) followed by a quality update (KB4023057).

My laptop used to give me similar problems when I first bought it and I had to take it to the service center after which it was a little bearable. But after this update, my laptop has become extremely slow.

It takes more than 2 minutes to boot up, another 30 seconds to get "Welcome"  and almost a minute to shut down. Also, after this update, I have observed that desktop windows manager and antimalware service executable takes up more than 70% of my Memory while idle. Overall, my laptop has become very slow and it sucks that HP's laptops always give this kind of problems. My friend updated his cheaper Asus laptop with the same specification too, but it runs smooth like a butter.

What have I tried, without any order:

1. Disabling background apps for solving issues with Desktop Windows Manager (Didn't help).

2. Ran scans like SFC /Scannow, DISM's Repair Health module and Chkdsk. Nothing helped.

3. Set paging to the recommended number. Operating my laptop feels a bit better now.

4. Tried clean boot.

5. Disabled Fast Startup.

6. And few other things as I saw in other community discussions.

My laptop has shown no improvement in booting. 

Note: I didn't try updating the BIOS. There was an update available once in older version of HP Support Assistant, it is not showing in the newer version of that software.

Please help.

Edit: As of now, I have updated my BIOS to F.36 and Windows to 21H1. No improvement yet.

Don't worry as I'll be glad to help, I understand that your HP notebook is not working correctly after the windows update. 
I have a few troubleshooting steps we could try to fix the issue. Firstly update BIOS: Follow steps from the link: https://support.hp.com/in-en/document/c00042629

Thank you for responding @Echo_Lake.

By the time of getting your reply, I have updated my BIOS to F.36 and also updated the Windows to 21H1 with the hope of seeing any improvement in my performance. But, it turned out to be of no use.

I assume using the Recovery Tool means resetting my pc and thus losing all of my data. However, currently, I have no way to backup my files anywhere else so that wouldn't be possible for me.
