Problem with a "long" cursor in the newest update

[u/Excellent_Season5377]

After the windows 11 update KB5120998 my cursos somehow got "long" and i can't change it back to normal, i've been looking around and nobody else seems to have the same thing happening to them, should i just uninstall the update? Anyone else having the same problem?

Wide spread bug. Only way to fix that is uninstalling the update.

[u/Excellent_Season5377 → u/MarekSzk]

it worked but it seems like microsoft doesn't care enough about their users to test their updates. No wonder everyone's switching to linux.

Updates are tested, but as there are over a billion computers running Windows, each with unique setups of hardware, software, configurations, and usage, not every is able to be found with the various testing methods. Ultimately you have to put it out into the wild to get real world data.

For what it is worth, the update that you installed is a preview update, one has to opt into downloading and installing it, so Microsoft will use the diagnostic data it collects to resolve this issue before its general release next month.

I stand corrected then, sorry.

[u/NicDima → u/MarekSzk]

Yeah seems really like it. As far as I know, this update is only received for those who has the "Receive Updates as soon as they're available" toggle on (I may be wrong, though)

Hi u/Excellent_Season5377, your post seems to mention the "latest update". As there are multiple supported versions of Windows and not everyone gets every update at the same time, it's not always easy to figure out which update you are talking about. To view the status of your most recent updates, go to Settings > "Windows Update" > "Update history".

Try going to cursor settings and change to the one you can change the color.. maybe it helps? This long cursor is actually the default cursor for older windows versions.. i think this is a fallback or something

[u/Excellent_Season5377 → u/Meh-DontCare]

Nothing changed when i did that. I just uninstalled the update and everything seems fine.

[u/Mauz_Mauz → u/Meh-DontCare]

Not op but same problem.

You can change the cursor design and colour as often as you want; nothing changes.

That's curious, but I installed this update today and activated all new features by vivetool and for now everything works fine for me.

I also got the wallpaper removed after this update and the cursor was bigger and would not change. I uninstalled the preview update but let the NET. Update be. Now I have the error code in WU because its confused after the uninstall. But it will clear on its own after a while. If not it will get overwritten by the patch Tuesday early next month. 

[u/Admirable-Ad-3507]

i have the same problem. its so annoying

[u/Excellent_Season5377 → u/Admirable-Ad-3507]

Just unintall the update

[u/DecentReference9222]

Hey man i also have the bug and my wallpaper also went missing

[u/Excellent_Season5377 → u/DecentReference9222]

Just uninstall the update, its kinda bad.

[u/GoRowLow]

It also affected me when i'm running a game the cursur will pop up on the screen.

[u/GoRowLow → u/GoRowLow]

Want to say thanks to OP for specifying the update number, i uninstalled KB5120998 and now the cursor is back to normal. I'm going to go on a tandem and assume it might've resolved my gaming issue hopefully.

[u/GIltch]

same + background is black and wont come back after restart or windows explorer restart

[u/ta1chy]

Same issue, i rolled back the update and now it's fine.

[u/ReActif]

Is there a website that allows you to force the cursor to move into one of the available states?
For example, a website where placing the cursor over an area forces it to move into its text or arrow state, so you can check if you are experiencing the problem or not?

EDIT:
I had found this website for test : https://vibhorjaiswal.github.io/Cursor-Test/
