Last weekend I had to update my girlfriends laptop from Windows 8.1 to Windows 10. Some might say, an easy task. Well, it wasn’t. After downloading the Windows 10 update through Windows Update, Windows Update returned errors
0xc190010b, even using the Windows 10 media creation tool. And as always there are many reasons for these errors. In this short post, I’ll provide some possible solutions and tips.
tl;dr, in my specific case, a WIMMount mounted image was the wrongdoer, and I had to delete that faulty mount point:
Delete sub keys of Mounted Images and check.
regeditand press enter
After deleting the sub key of Mounted Images in the Windows registry, the Windows 10 setup worked perfectly for me. There may be other issues involved as well when you’re facing these
0xc190010b Windows Update errors.
Therefore, here’s some more general Windows maintenance advice for you:
Lack of disk space may cause various Windows Update errors. Always keep your disk clean, regularly clean up your temporary directories and unneeded download files.
Clear all your temp directories:
%temp%and press enter
Clear all downloaded Windows Update files:
Clean up Windows Temp folder:
Talking about Windows disk clean-up, I have a post summing up 5 extra ways to clean up disk space in Windows Server!
An activated anti-virus program may interfere with the Windows 10 update, so temporarily disable your AV software. Usually there is an icon at the lower-right corner of your screen, use the left or right mouse button to pull up its menu and choose disable.
It’s possible you haven’t installed all available Windows updates yet, and one of them is needed for the Windows 10 update to install successfully. Always install all available and pending updates, it keeps your computer more secure – as vulnerabilities are fixed – often makes your computer run faster as an update is more optimized.
The System File Check utility, or
sfc.exe is used to verify the integrity of important Windows files. When used properly,
sfc.exe repairs corrupted system files.
sfc /?to review its help and options, and
sfc /scannowto scan your system
When a Windows 10 update has failed, you’ll find (some of) its files in a directory
C:\$Windows~BT. Before trying the update again, the directory needs to be deleted – or if all else fails, renamed. Open up a CMD command line prompt as administrator, and execute:
cd \ rd /s /q \$Windows~BT
If you’re an advanced Windows power user, you could try changing file- and directory permissions and ownership if the command should fail. Otherwise, just rename the directory:
ren \$Windows~BT \$Windows~BT.old
And last but not least: Learn how to keep Windows up to date, fix errors and other issues with Windows Update. Fix the problem yourself or get help from the community:
Microsoft Support website.
And that’s it. After all this, your Windows 10 update from Windows 8.1 should work just fine.
What’s the meaning of 0xc1420127 and 0xc190010b? Just look it up with
err.exe, Err.exe is a great command-line utility for looking up error codes. Get Err.exe at http://www.microsoft.com/downloads/details.aspx?familyid=be596899-7bb8-4208-b7fc-09e02a13696c&displaylang=en (MSDN says it’s for Exchange error codes but it works for Win32 error codes and many more).
