Question

Why is my computer running slow after the latest Windows update?

Joe Davis 25

Why is my computer running slow after the latest Windows update? I’ve noticed a significant drop in performance since installing the update—programs take longer to open, the system lags, and even simple tasks feel sluggish. I'm not sure what's causing this, and it's starting to affect my productivity. Could it be due to background processes, incompatible drivers, or something else introduced by the update? I’ve tried restarting a few times, but the problem persists. Are there any specific steps I should take to troubleshoot this issue? Should I check Task Manager, update drivers, or consider rolling back the update? I’d appreciate any suggestions on how to fix this and get my computer running smoothly again.

Same thing for me, most noticeable in games. Been playing Metaphor ReFantazio for weeks now, and suddenly since the very recent Windows update, every location transition went from taking <1-sec to up-to 20 seconds on my extremely high-end rig. Does this have something to do with the SSD failures caused by another one of MS's recent updates? Maybe some attempt at mitigation introduced another problem. *Edit: I'm on Windows 10.

Answer 1

The issue of my computer running slowly after the latest Windows update has now been successfully resolved. After experiencing noticeable lag, delayed program launches, and overall sluggish performance, I began troubleshooting by checking the Task Manager, where I found several background processes consuming high system resources. I disabled unnecessary startup programs and updated all outdated drivers, especially the graphics and chipset drivers, which seemed to be affected by the update. Additionally, I performed a disk cleanup to remove temporary and leftover update files, ran a malware scan to rule out any security issues, and adjusted the system's performance settings for optimal efficiency. These steps collectively resolved the performance problems, and my computer is now running smoothly and efficiently once again.

Hi. Before rolling anything back, I suggest testing with a clean boot. This will disable all non-Microsoft startup apps and services, helping isolate whether the issue is being caused by something running in the background.

Try this:

Press Windows + R, type msconfig, press Enter.
In the Services tab, check Hide all Microsoft services, then click Disable all.
Go to the Startup tab, and click Open Task Manager.
In Task Manager’s Startup tab, disable everything.
Close Task Manager, click OK in the System Configuration window.
Restart the PC.

What this does: It prevents all third-party services and apps from starting, so you can test system performance under minimal load.

If performance improves significantly, something in your startup is the problem. From there, re-enable services and apps one at a time to isolate the culprit.

I can honestly say that I NEVER expect to obtain a resolution to a problem by MS especially a problem CAUSED by MS. It's quite obvious that if a computer runs perfectly before an update but not afterwards then the issue is with MS not us or our computers. IN my case this is especially annoying since I had only recently spent 4 days reinstalling W11 not once but 3 times before being able to get a properly working version. Then after the update I found that my restore points had been removed by MS so I now have to start over. Why don't MS make a simple operating system for those of us that don't want all the features and AI that we now get?

I am having similar issues after installing the update. Massive lag when I try to begin typing. Takes my PC 5 seconds of lagging before it registers my keyboard inputs
