This free tool created by
niemiro is a very good starting point for the diagnosis and repair of all Windows Update and System File Checker corruptions. We therefore need you to run this tool prior to collecting logfiles.
- First download and run a copy of the tool from SFCFix Official Download - Repair Windows Update.
- Work through any on-screen prompts and then await completion (runtime can be upwards of 15 minutes depending on the options you selected during the on-screen prompts).
- Once it has finished, if there are any unrepaired corruptions (the tool will notify you if it has succeeded in repairing all corruptions if they're simple in which case we're no longer needed) or unresolved problems with your computer, you need to post us the complete logfile which opens on exit. Simply copy (Ctrl-A, Ctrl-C) and paste (Ctrl-V) the entire logfile into your new thread (also known as a 'topic'). How to create a topic is shown later on in this post.
- Continue to Step #5 if you are still having issues with your machine relating to Windows Updates/SFC/DISM.

What to do if your CBS logfiles are too large to upload
Read More:
In some instances you will be unable to upload your CBS logfiles to our forum because they are too large.
To work around this problem you need to use a file sharing service to upload your attachment and then provide the link that is generated by the hosting service in your post.
Several file sharing options are listed below (they are clickable links), however you are not limited to these:
Microsoft OneDrive
Google Drive
Dropbox
ExpireBox
SendSpace
WeTransfer
