I am using a Canon MDF656cdw. There are work arounds for that scanner on the Canon Community. My scanner is now working.

Since I believe you are the first to discuss the problem with the W11 Update with the Version of 24H2, I am wondering if someone could advise me from here on out, whether I should or should not unselect Windows Update to be automatically updated or just to do it manually? For now I have unselected it and if there are any Windows Updates, I could wait for signs of problems such as this 24H2 Version which was causing havoc on so many computers. Sorry, it's late and I am very tired so I hope I made myself clear. Please advise! Thanks

Eric-Moore - This worked for me. I was skeptible but tried the method that Tomasz_216 suggested. So simple too! I copied and pasted his reply here again for convenience. Good Luck!

Tomasz S_216 has replied to the question Windows 24H2 issues with Scanning that you are following in Microsoft Support Community.

Quoting a temporary solution (I tried, and it works.):

Steps as what I did:

1. Finish the installation of your printer driver full package normally (Checked on 24H2, OS Build 26100.2605 - Dec 10,2024 Windows updated PC) and it will end up with only scanner driver installation failed. (Basically it won't scan from Control Center 4 scanner app and if you want to check, open 'Brother Utilities'-->Tools-->Installation Diagnostics, it will tell you only Scanner driver installation failed).
2. Go to 'Device Manager' --> Imaging devices --> Right click on 'Your printer name' --> Disable device
   (Not delete, but disable!)
3. Again Right click on it, but this time click on Update driver --> Browse my computer for drivers --> Let me pick from a list of available drivers on my computer --> on next window you should already have your printer name, just select and click on Next.
4. On next screen you will see successfully installed a driver and click on close, Imaging device which you have just disabled will be enabled by system and then close everything, do a restart once.
5. Just use Control Centre 4 as you usually used to scan something and it will work this time.

This worked for me on Brother MFC-B7715DW. Many thanks!

Same Issue with HP Laserjet Pro MFP 4302fdn. Prints fine, but can't detect the scanner exists. Microsoft "fax and Scan" is ok. HP scan Doctor reports all sorts of spurious errors (device drivers, WIA not working etc).

I'm not brave enough to roll 24H2 back, so will stick with Scanner to email on the device for now.

Great Microsoft, so users now have to give up on security because you can't push out an update. When is this going to be fixed? Your users deserve an answer.
