Windows 10: WimMount question

Hi Forum, I have a folder called WimMount in my c drive. It seems to have an entire other windows in it?
can someone please tell me what it is for? Also, when I right click on the folder and click properties, it reports the size as 11.2GB but the size on disk says 38.4MB ??

Thanks in advance for your response.

:)

 

Windows 10 Upgrade Something Happened

Try searching setuplog for Wimmount. If setup cannot find wimmount you'll get the errors. Setuplog will tell you where setup tries to find wimmount. Copy wimmount to this location.

The SQM errors comes even when it works smoothtly. and they are there long before the wimmount error

 

Installer closing at ~6% (wimmount?/0x80070003)

At least for me, I was able to find a pretty simple fix for this problem although I was upgrading from Windows 8.1 Update.

AFAIK, this should still fix the problem on Windows 7.

The issue:

It seems that for some strange reason the installer does not include `wimmount.sys` which is what it's trying to look for. So, it ends up trying to find it at the default location which clearly does not exist causing the installation
to fail.

The fix:

So, clearly we need to properly get the installer the recognize `wimmount.sys` located somewhere. To do that all we need is to get it installed. To do so:

• Download the "Windows Assessment and Deployment Kit" from:
  
  Download Windows Assessment and Deployment Kit (Windows ADK) for Windows 8.1 Update from Official Microsoft Download Center
  
  (it says "for Windows 8.1 Update" but it says it can run on Windows 7 and other versions of Windows)
  
• Run the installer (it may take a minute or two for the blue splash screen to go away)
  
• "Specify Location"
  
  Leave the default option selected which should be "Install the Windows..."
  
  (FYI: the installer says it uses ~6GB, but we will select only what we need, that being ~50MB, so you aren't killing your internet bandwidth nor wasting time)
  
  Click Next.
  
  
• "Join the Customer Experience Improvement Program (CEIP)"
  
  (You can just leave it set to No unless you feel otherwise )
  
  Click Next.
  
  
• "License Agreement"
  
  Click Agree.
  
  
  
• "Select the features you want to install"
  
  IMPORTANT: Deselect everything except "Deployment Tools"
  
  (as said, this keeps you from downloading GBs of unnecessary stuff)
  
  Click Install.
  
• If you have UAC enabled, click Yes.
  
• Wait for the install to complete...
  
• Click Close.
  
• Try running your Windows 10 install again. The installer should recognize where `wimmount.sys` and now be able to successfully install Windows 10.

So, let me know how it goes

Cheers,
