Windows update kb5005033 failing to intall

Here's a pretty good run down of things to check...
Windows 10 - Windows Update error 0x80070003 on - SuperTechman




If you use Macrium Reflect, here's something else to check as well.

After a month or more of trying all the standard fixes I was finally able to solve my Windows Update failure problem that displayed error code 0x80070003. I am posting here in case others may benefit. It appears if you use Macrium Reflect software this may help you but I could not confirm that the problem was caused by Macrium. So whether you use Macrium or not see if this helps you.

In the Registry Editor (click the Start Menu icon and type regedit), go to this location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WIMMount

FIrst thing to do is make a backup of this entry in case anything goes wrong. Right click on WIMMount and select Export and save the backup somewhere.

Now click on the top level WIMMount entry (if you expand it you will see Instances and WIMMount sub-directories but we will not be using those) and in the right side panel you should see 11 or so entries.

Find the entry with the name "ImagePath" and make sure the Data column shows this: system32\drivers\wimmount.sys

If it does not say this, click on "ImagePath" and change the Value data field to system32\drivers\wimmount.sys
In my WIndows 10 registry, this entry showed something different so I changed it. I confirmed this entry on my two other Windows 10 PC's.

Finally, check to make sure the wimmount.sys file is in this location: C:\Windows\System32\drivers\wimmount.sys

And last but not least.... if all else fails...



Repair Install Windows 10 with an In-place Upgrade



Here is the short version of the In-place upgrade tutorial...

DISABLE non-Microsoft:
a) antivirus software
b) firewall software
c) drive encryption software

Make a full OS backup with a program like Macrium Reflect (free)
Macrium Software | Macrium Reflect Free

Go here and get the Media Creation Tool and save it to your desktop.
https://www.microsoft.com/en-us/soft...load/windows10

RUN the Media Creation Tool and use it to: Create an ISO image... save IT to your desktop.
This will be the latest version of the ISO image.




Right click the ISO image and choose: MOUNT
Open File Explorer and you will see a new drive letter. It will look like a DVD optical drive.
Double click the new drive letter to open it.
Find setup.exe and double click it to start the in-place upgrade.

Choose the Keep personal files and apps option.

After it's all done... to UNmount the ISO image, right click the new drive letter and choose: EJECT.


The ONLY thing you will lose is some of your personalizations. Your programs and data will be intact.
