Having same Issue with KB5034441 Update 01-11-2024 fails to install 0x80070643.

Thanks Jonesy847. I also ran into the "Windows RE Image Not Found" error and it also was a Win10 " Pro " so your hunch might be correct. I hadn't noticed but my recovery partition was also not in use after fixing the error and the recovery files were now on my main C: partition. Moving the recovery from one place to another is possible if you follow this answer . I had to manually create N:\Recovery\WindowsRE in an admin command prompt and apply the image to that directory as Dism said I can't apply to the root directory. Make sure your captured C:\recovery-partition.wim is 400-500MB. Dism will claim success and create a 4-5KB file if you capture from the wrong directory. Dism /Capture-Image /ImageFile:C:\recovery-partition.wim /CaptureDir:c:\Recovery\WindowsRE /Name:"Recovery" Dism /Apply-Image /ImageFile:C:\recovery-partition.wim /Index:1 /ApplyDir:N:\Recovery\WindowsRE I'm sure MS puts the recovery files on a separate hidden partition for robustness reasons so I feel better having moved it back to its proper partition. I deleted C:\recovery-partition.wim when done but keep it if you want.

I have tried many ways to correct the error code 0x80070643 including using the bat file "Wufix.bat" which required over-night to run. Nothing corrects the problem. Please help me. If possible, please provide a telephone number that I can use to call you and/or Microsoft support. Russell C Anderson ******@Gmail.com 928.713.2948 Thank you

I downloaded partition wizard which is a free use and download program. With this I was easily able to double my hard disk partition size from just over 500Mb to 1Gb as from what I can see KB 5034441 fails to install as most hard disk partitions as installed with Windows 10 that I use, are too small for this update and this is why this update installation fails. I have plenty of additional storage on my system, so it was a no brainer. It takes about 35 minutes on my system for the partition size to be increased which is a little worrying however be patient. Once the partition size was changed and after the necessary reboots my system works perfectly, and KB 5034441 installed no problem first try. It's still amazing to me that Microsoft can issue a mandatory update that simply does not work using their own basic systems and we have to go through this hair-raising experience to fix what is simply something they created and did not adequately test. I hope this helps those that have had the same experience as me. Mark Green
