Super Slow Start Up

Question

Super Slow Start Up

Tim Rogers 250

Hello;

Since the last update 2025-09 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5065426) (26100.6584)

Which was Successfully installed on ‎2025-‎09-‎09

The start up time on my PC is so slow, that a slug can beat it to the desktop.

Not only does it takes more then 2 minutes to get to the slideshow I have on my start up, which used to take less then 30 seconds, when I put my PIN in and enter it takes any where from 30 seconds to 1 minute 25 seconds to get on to the desktop. When I get there it takes another 2 minutes for all the apps on my PC to get running.

Before the update, within 20 seconds I was on my desktop, and all my apps were running, all I had to do was sign in to my password manager.

Any body else out there experiencing this kind of lag on start up.

I had the same problem. After trying everything for a few hours, I uninstalled this update, and my computer worked like before.

On task manager I was seeing about 70% CPU usage but nothing was using more than 5% which would count to only about 25%. I also found that my SSD was getting hotter but I could not find what was going on. I deactivated updates for a while.

You are correct on that. This might be a compatibility issue between the PC drivers and the newest update. In this case, I suggest doing a system restore, which will restore the PC to when it was working properly. To do that, kindly follow the steps below:

Press the Windows key + R, then type in:

rstrui

Then hit OK.

Follow the prompts and select the time and date when the PC is working fine.

Follow the prompts again until it restores.

Or another option is to wait for another update, and I highly suggest posting the issue on the feedback hub so that developers will also be aware of this problem, and hopefully, the fix will apply as soon as possible.

Hello LBR I read the first line of your second suggestion. "I suggest doing a system restore"

I hit Windows icon on the taskbar and typed system restore and then went to the restore point I created on the 7th.

Pushed the apply and 22 minutes later the pain in the butt start up issue is now gone.

I now have my slide show back on the start up screen as well as my widgets, and this has definitely proved to me that Microsoft really does need to stop putting out cumulative updates, and break them down to each series separately.

That update may have been important, but messing with the operation of my PC negates installing it and now that I have a properly working PC again, all future updates are on pause for a month.

Then another restore point done manually, then we see what happens when I reactivate the Updates.

Lessons from previous problems have taught me to do this.

Eventually Microsoft fixes their little glitches that always seem to get through.

As for the feedback hub, that was taken care of right at the very beginning of the entire episode.

I even talked to an agent through Microsoft Help who suggested a Reset, which from other postings about the poor operation of the Reset, that was absolutely out of the question.

Answer 1

Hi, I'm Bernard, a fellow Windows user. I'm happy to help!

I understand the issue you have. There is nothing to worry about. I am here to assist. This issue occurs when there are unnecessary services running in the background. To sort out the issue, kindly follow the steps below:

Do a clean boot:

A “clean boot” starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program.

In the search box on the taskbar, type msconfig and select System Configuration from the results.
On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
On the Startup tab of System Configuration, select Open Task Manager.
Under Startup in Task Manager, for each startup item, select the item and then select Disable.
Close Task Manager.
On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.

Note: If the issue persists, a system restore or system repair might be necessary to sort out the issue.

I will try that and see what happens. with all my apps shut off, only Windows should boot fast like it used to.

If it is my apps causing the problem, there is a few hours of chasing down the culprit.

If it still slow boots, then for sure it is because of the update.

I will let you know. Time is 5:15 PM

The time is now 5:26 PM and following your directions, the start up did not change one millisecond.

With just Microsoft on the menu.

The slugs in my garden could produce the desktop faster. [LOL]

So it is just as I expected, that last update did something that I hope will be undone when I roll that Update back.

Same slow startup here after update to KB5065426 and latest KB5065789. Tested on 3 different PC`s issue still persist on all, so don't think is hardware related problem. Uninstalled update for time being but that's temporary fix only. Will wait for MS to sort it out hopefully.

Hi, thank you for replying. I am glad that system restore sorted out the issue, and you are correct, the best option as of the moment is to wait for another Windows update that will address the issue you have right now.

Tried as you said and just essential Microsoft to get to desktop 2 minutes to the desktop.

Every other application was shut down.

It seems that my hunch about the update is correct.

I just hope that what ever it was will clear out on a roll back.

This snails pace to the desktop reminds me of Windows 95, sign in, go get coffee, come back just as desktop pops up.
