Windows 11 update is reportedly slowing down PCs and breaking internet connections
Windows 11 just received a new cumulative update (Moment 3) a couple of days back, and don’t look now – well, actually do look, or you’ll struggle to read this article – but there are complaints filtering through about a number of issues.
The main bones of contention with patch KB5028185 for Windows 11 22H2 are instances of performance slowdown – with severe cases going by some reports – and problems with flaky internet connections.
Let’s tackle the performance bugbears first, and it might be worth noting to kick off that the sluggish SSD issue still isn’t resolved with this update, as we recently predicted (that’s been an ongoing barrel of woes).
Aside from that, on the Reddit thread announcing the update we see multiple complaints of PCs running more slowly, and/or booting more sluggishly.
For example, one Redditor notes: “KB5028185 is trash. Thanks to this update, my restart and startup times are both far longer, sitting at the Welcome Screen for 17 seconds where it used to be about 4½ seconds. The shutdown time is longer too but I didn’t time it.”
That problem went away after uninstalling the update.
Another user observes: “Why after [updating], all my games and apps became very laggy?”
And another person replies to that: “Same happened to me. Can’t believe how abysmal the performance is. I uninstalled the update and it’s back to normal. I hate how Microsoft forces such broken updates all the time in Windows 10/11. Never had this problem with Windows 7/8.”
A further complaint reads: “Has anyone else been dealing with your PC chugging super hard after the update? Worked perfectly fine last night, got the updates this morning, took 4 hours for the updates to download/install, another 45 minutes to properly install after 2 restarts, and now, 4 hours later after the restarts completed, everything is STILL super slow.”
Okay, onto the second major issue that’s being reported, namely the internet connection going down the proverbial tubes. There are reports of both Wi-Fi and Ethernet (wired) connections being hit.
Again, here are some posts from affected Redditors. One person writes: “My pc won’t get on the internet now. No wifi or ethernet. And my firewall won’t start. Was fine before this ‘update.’”
Here’s another: “My Ethernet does not work as well since yesterday’s update… Edit: After removing updates KB5028851, KB5028185 via settings menu, my Internet connection is working again! Took 10 minutes.”
And another: “KB5028185 broke my internet also, no connection via Ethernet or WiFi/hotspot, they both said ‘connected, but no internet available.’ The troubleshooters were useless in resolving the issue so I decided to uninstall the update and everything works fine.”
Elsewhere we see complaints about Wi-Fi network stability in general.
A third annoyance here is the Windows Security icon in the system tray (far right of the taskbar) is broken in some cases, meaning nothing happens when you click on it (but virus scans are still working okay). Again, there are multiple confirmations of this glitch.
Analysis: What to do? Well, there are workarounds, but with catches
It seems that KB5028185 is problematic on a number of fronts, sadly. If you’ve installed the July cumulative update and have run into one of these problems – or random crashes, which we’ve also seen reported – then a temporary workaround is to uninstall KB5028185.
The downside is that you’ll be left without all the latest security fixes on your Windows 11 PC, which isn’t great. And also, the update will automatically install itself eventually (you can only put it off for so long with Windows 11 Home edition).
Meantime, all we can do is hope that Microsoft is investigating the aforementioned bugs, and will be producing some cures for the PCs hit by these problems.
The only other suggestion floated on Reddit is turning off Core Isolation (Memory Integrity), as some folks have claimed that this is causing most of the problems around system lag and crashes. Turning it off – just search for ‘Core Isolation’, go to the panel, and click the slider to disable Memory Integrity (then reboot) – may remedy your performance issues (or indeed internet dropouts), we’re told.
However, there’s a big caveat here, namely that this is a security feature you really should have running to defend yourself against potential exploits.
So, you’re taking a chance either way – running without the update, or without an important security feature – but if the problems with KB5028185 are bugging you that much, it may be a chance you want to take (at your own risk, as ever).
