Logitec Camera C210 (maybe C270, QuickCam Pro 9000, C525, C170) - Error - lvrs64.sys , lvuvc64.sys Windows 11 memory integrity

Problem

The problem with legacy/old Logitech webcams on Windows 11 machines are the drivers: lvrs64.sys and lvuvc64.sys. These drivers are blocking Windows memory integrity.

Solution

I fixed this error by removing all the drivers from Win11, and use native Win11 drivers.

• Press Windows key+X > Device Manager> Imaging Devices > Uninstall device > remove with drivers.
• Disconnect and connect camera [Error will pop up, ignore it]
• Press Windows key+X > Device Manager> Sound, video and game controllers > Uninstall device > remove with drivers.
• Disconnect and connect camera
• Test camera in Zoom Settings > Video > Camera> select 'USB Video Device'

Make sure there is not lvrs64.sys and lvuvc64.sys in C:\WINDOWS\system32\drivers

NOTE: Do not waste your time installing Logi Tune Software.

UPDATE 21/July/2026

Other Logitec models fixed and mentioned in your comments:

• C210
• C270
• QuickCam Pro 9000
• C525
• C170
• C510
• C920 PRO

Worked like a charm! Picked up the QuickCam Pro 9000 for $2.50 and i was having this issue due to being on windows 11.

C525 broken after upgrade Win 11 24H2

It's ok after this tips ! Thanks

Thank you so much! This worked! I had to uninstall and reboot, removing drivers a few times as it kept coming back even after I deleted the drivers manually in C:\WINDOWS\system32\drivers.

Perfect, thank you.

Thank you, worked perfectly!

Worked for me too after upgrade Win 11 24H2, Webcam C170

Thank you! Worked like a charm on Win 11 Home 24H2, OS build 26100.2605, Logitech C525.
This issue was affecting camera's mic for some reason the camera video part was working fine.

Awesome thanks. I was having a weird coloring problem with my cam anyway. Hopefully this resolves it

Worked for me too - thank you.

Thank you so much, C525 worked

Worked here too, C170 after the Win11 24H2 update. Thanks for posting

Worked for me too after Win11 24H2 upgrade - C210 camera and microphone. Thanks for posting

Hello! Thank you for leaving a comment here. I am glad this personal note worked for you.

QuickCam Pro 9000, lvrs64.sys Driver error on Win11 OS, → That fixed it! Thank You.

I had the same problem, but none of the suggested solutions worked. The drivers weren’t in the DRIVERS folder, and neither the command line nor other methods worked. I found the incompatible drivers mentioned, but they were in the DRIVERSTORE/FILEREPOSITORY folder. However, I couldn’t delete them, even though I was an administrator. I created a new LOCAL account on my computer because I already had an administrator account, but it was under a Microsoft account. And from this new account, I was able to delete these three incompatible drivers: btwrchid.sys, lvrs64.sys, and lvuvc64.sys. After that, nothing stood in the way of installing Windows 11. Have a great day.

Bro ! You are awesome ! I can use my C920 PRO now
For info : I did it in one go

• Device Manager
• Uninstalling the 2 drivers marked with the yellow triangle
• Disconnect and connect camera
  Job done

Worked also for my Logitech 525. Thanks :)

Thank mate, saved my C525 ! Fist bump
