  1. Hi there: Im having a problem with Sound on my HP Laptop. A Couple days ago my laptop stopped with the sound. I have tried looking for everything to try to fix this but nothing helps. Anybody Know what is causing this or how I can fix this? I tried a Factory reset but the sound still doesnt sound.

  2. Same here. The volume control would go to mute even after I adjusted the volume to 100 %. I rebooted my computer (HP 2X laptop) and volume control would still go to mute. I then uninstalled KB4549951 but didn’t reboot. Surprisingly the volume control would lower the sound to around 50 % but not all the way to mute. Finally I rebooted the computer and this fixed the problem. The volume control now appears to work as it should before I installed this patch. I must say that this is a big defect that I would think Microsoft would have discovered before the patch was issued.

  3. I’ve had to uninstall this update on all three of my computers (two Lenovo laptops and an HP Omen desktop). For all of them, after the update it doesn’t recognize that an SD card is plugged in. The card is fine. If I uninstall the update, it sees the card; no problem on all three.

    Fortunately it isn’t a BSOD problem, but I put files on an SD card quite often, so it is a problem for me.

  4. Windows 10 will no longer allow me to use a website link to save link as file to downloads. MS Edge and Firefox freeze and the browser fails to download svg and png files from websites.

  5. “… the only way to fix the problems that emerged from this update is by installing this update.”

    Should be “uninstalling”?

  6. My partner and I both have HP Spectre x360 laptops and after this upgrade, both of them would fail to charge the battery. The latest update fixed the problem.
