Windows 10: Boot time takes very long after optional update KB4535996

Hello,


On February 28 I installed optional update KB4535996 on my PC. Since then the boot time is taking way longer than originally.

My PC is Acer desktop with Intel Core i5 6400. The machine is with Windows 10 Home 1909. I tried to uninstall 4535996 but the system is not allowing me to do so.

:)

 

windows update kb4535996

Does windows 10 kb4535996 replace kb4524244 and kb4532693?

 

laptop doesnt boot automatically

This is what happened.

1. Did a repair install and later disabled hibertnate in CMD.
2. Enabled legacy option ROM in BIOS.
3. After a few times startup ( i used the system in such mode for 5 days), changed boot option back to default.
4. Vola!! It boots automatically to win10 without any keypress. Tested it with many starts to confirm the same.
5. Re-enabled hibernate option using CMD and later selected Fast Startup.
6. System booted normally, without the need for any keypress.

I do not know exactly whether such steps resolved the problem or what else happened, hence cannot suggest above steps.

Many thanks to all members who helped to troubleshoot problems.

 

Re: All boot options are tried...

Hi Elda,

If the boot sequence didn't work, then we suggest try running the laptop in safe mode. To do this, here's a few steps to follow:

• Power down your laptop.
• Turn it back on again.
• When you turn it back on, press F8 repeatedly until the power on option appeared.
  
• If you see the boot option "Safe Mode with Networking", choose that option.
• See if you can boot up in Safe mode.

We'll look forward to your response.
