Windows 10: • Feature update to Windows 10, version 1607. Problems

I try to open the iis .txt file and "Access is denied". Do you think I could try to run the update again?

 

Yes - you'll need to copy it to another folder and look at it there. You'll need to provide admin permission, but it should allow you to copy the file.

 

Here is the file.

 

I can't see any errors in there, I must admit.

Yes I guess so.

 

Once again failure occurred at 40% with the same error code when booting into my restored version of Windows. If my current version of Windows is happy with my system, I wonder why this update isn't?

 

My only suggestion is to try the remedy at the end of that MSDN blog post, which is to delete 3 specific keys from the folder: C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys. To be safe I'd take copies first and store them in another folder before deleting.

There may be more files in the folder, but I think it's these specific ones you want.
Then try the installation again, I guess.

It's past bedtime in this timezone so logging off now...

 

Thanks. I will try your suggestion. BTW, there are 280 lines in that folder. All of them hexidecimal at least twice as long as those 3 files I'm supposed to delete, with no words in them.

 

Failure happened exactly as all the times before.

 

I believe that there is still some issue with IIS, or some file related to its configuration.

When Windows tries to upgrade to the next version, it tries to migrate IIS from the old windows version to the new one, and it trips over that issue, causing the installation to fail.

Some more things to try:

• Make sure you have a good backup
• Switch off those two Internet Information Services features in the same place as you switched them on before. I'm assuming here that you don't need IIS to run some sort of internet feature?
• You may have already done this but if not, run the SFC (system file checker) command - see here: SFC Command - Run in Windows 10
• Depending what that says, you might want to use DISM to repair the Windows 10 image - DISM - Repair Windows 10 Image
• Restart the computer
• Try again from the 1607 ISO route suggested earlier.

 

I ran the SFC scan and got this result:




I am running the restore health cmd now.

I wish I could attach the log file. But it is showing 38KB in the Documents folder, and 38MB on the desktop. I cannot bring it in here from either location.

 

I would love to attach the log file, but it is 2.38MB and this forum has a limit of 2.00MB

 

If you right click it in the Documents folder, there should be an option to "Send To", and then within that "Compressed (Zipped) Folders" (which should create a ZIP file).

The 2.38MB file should zip to less than 2MB easily though?

 

I will try to attach here.

 

It might be worth seeing if you can do the same Zipping issue to the CBS.Log file wherever it is.

How did Windows 10 get onto the machine? Did it come with Windows 10 or did you upgrade it?

In order to stand more chance of repairing the issue, the DISM command would need a Windows ISO or possibly a file from a recovery partition or similar, whatever problem it was, but it would need to be the ISO for the original version of Windows (10240) rather than the ISO you downloaded recently.

I don't suppose you have an ISO file for Windows 10240? (Pretty sure you can't download it from Microsoft any more.)

It's also possible that while SFC didn't fix everything ,it may still have fixed enough to make it worth attempting the windows installer again. Make sure you do a Restart first though.
