Windows 10: Cumulative Update for Windows 10 Version 1511 KB3135173

had this before update
an app caused a problem with the default app settings for .pdf files, so it was reset to microsoft edge
update installed
an app default was reset
an app caused a problem with the default app settings for .jpg files, so it was reset to photo
then had 4 of
an app caused a problem with the default app settings for .png files, so it was reset to photo

 

Same thing happened to me. I had to right click the PDF file and use the open with command to select Sumatra as the default application to make it work again. I needed to do it twice for some reason, but seems to be working now as it used to.

 

Hi,

Tried that but no joy. Restored from previous image and no problems!!!! Way to go Microsoft asses.

 

10586.104 installed smoothly, and does seem snappier....BUT, the Regedit search issue that was fixed in 10586.71 seems to back in 10586.104. I restored an image of .71 to check, and it worked. Put the .104 on and it's broken. Maybe just me, only pointing it out.

 

That's just another reason I'm glad I never use Windows regedit. I have always used Registry Workshop registered. *Smile

 

Please could you remind me what the Regedit search issue was?

Just did a search using Regedit running build 10586.104 and didn't have a problem.

 

I didn't see this on my user account. But after the update I setup new user accounts for my wife and son and got those exact same messages as it was setting them up after login for first time. Not that it has any lasting effect as I tried Adobe with opening pdf on my wife's account and it was fine so just put it down to a one off glitch.

 

It wasn't happening for everyone. Only if there was a certain subkey in the registry >255 characters.

Thanks for the reply.

 

I try to i nstall but have problems. Error 0x80070020

 

go to control panel, all items, troubleshooting, system and security, fix problems with windows update.

It fixed the issue for me.

I have since disabled automatic updates of Apps in the store, and also, I do not allow Win10 to automatically install updates either. I prefer to do these myself when they are available, when it suits me..

 

I followed the steps you told me but same problem.

Thanks you

 

@cheenu, you might want to clean that up a bit before someone does it for you.

 

Have you tried installing the update this way
