Windows Booting very slow after 2004 update ,

Leave it to a Windows update to screw something up. I didn't install the 1909 update ,but installed 2004 on 6/05. Noticed a couple weeks ago it took longer to boot ,but didn't think nothing about it. Restarted my laptop yesterday just to check and it was still slow. I timed it today and it took 11 minutes and 32 seconds to go from the Windows/HP logo screen to the user sign in screen. You add the "Restarting" screen and after sign in and it would take like 15 minutes for a restart. Before the 2004 update and it was nowhere close to that long. I tried these things recommended online and nothing has fixed it.

1: Make sure latest drivers for GTX 950M and Intel 530 Graphics

2: Disable startup programs

3: Install trial version of Malwarebytes and scanned(Came back clean)

4: Disabled GTX 950M Graphics

5: Turned off "Fast Startup" in power settings.

6: Tweaked "Performance" settings

7: sfc /scannow

8: Defragment

@AFWS I assume the GTX950M is for an external monitor, as you have disabled it?

Anyway, on a related post, a user with Gigabyte X570 motherboard found that in the BIOS, turning off the SATA HOTPLUG made his reboot time issue much better. NOTE: that might only apply to certain motherboard types, and must NOT be done if you have set up an active disk RAID configuration.

As for performance issues during normal working (post 2004 update), it can be beneficial to stop and disable the SYSMAIN, and Windows Search services.

Whatever was taking all day for a 'Restart' (not shutting down or booting back up again) has disappeared for me. Actually, the problem disappeared before the latest update so what that was all about is beyond me! But the slow 'Restart' (the circle just turning and turning and turning before the Restart would disappear) has done just that ... disappeared!

Is the Windows Search the same as the "Indexing Service" mentioned in previous replies. I looked for a Indexing Service ,but doesn't appear to be one. I got the SysMain and Windows Search now disabled.

Hi @AFWS - yes the Windows Search is the same as what others call the "Indexing Service". The ONLY downside I have seen is if you have the local Outlook mail client (via an Office Suite), the search function within a mailbox can give a warning that the search service is off, and may be a bit slower, but you can stop the notification of that in an Outlook setting.
