I don't know how I got there, but try this https://onedrive.live.com/redir?resid=F56F7AEBD0068A0B%21771 If that doesn't work, need step-by-step instructions. If you spell out the steps, I can follow. Thanks

@ showmethefacts , the CBS.log can get very large. I would suggest renaming it and the DISM.log and doing another 'Dism /Online /Cleanup-Image /RestoreHealth'. From an admin command prompt: cd \windows\logs\cbs rename cbs.log cbs.log-20150310 cd \windows\logs\dism rename dism.log dism.log-20150310 This time the CBS.log and DISM.log files were under 50KB. I went to https://onedrive.live.com/ , logged in and uploaded the two files. I then right-clicked on each file, selected Share / Get a link / View only and then Create link . It turns out that selecting both files at the same time results in a link that subsequently shows icons for the two files rather than immediately loading them.

Questions: Is this a single command prompt, or 4 separate command prompts: From an admin command prompt: cd \windows\logs\cbs rename cbs.log cbs.log-20150310 cd \windows\logs\dism rename dism.log dism.log-20150310 Then at what point to I create the log by pasting the CBS stuff in a browser window?

@ showmethefacts , open an Admin command prompt and paste in the four commands in sequence to backup your existing log files. From the same command prompt, you can then run Dism /Online /Cleanup-Image /RestoreHealth which will create new log files. I am not a OneDrive expert so there may be a better way. I opened a browser, went to https://onedrive.live.com/ to access the OneDrive web user interface and did the uploads of c:\windows\logs\cbs\cbs.log and c:\windows\logs\dism\dism.log followed by creating the share links. No need to convert the logs into PDFs.

OK, I know I this is tedious, but when yo say: "paste in the four commands in sequence to backup your existing log files," do I paste in one at a time and hit "enter" after each? Or do I paste them in all at once? I tried the latter to no good effect. And if I do the former, do I create a log after each one, thus making 4 cbs logs and 4 DIMs logs?
