Hi,

Yes, as arnavsharma said, you can keep your files, settings when upgraded to Windows 8.1, only some Windows Store apps will need to be reinstalled from the Store, but it is always recommended to backup important files before upgarding.

If you choose to Keep nothing when you upgrade to Windows 8.1, please refer to this link to retrieve files from Windows.old folder

http://windows.microsoft.com/en-IN/windows-8/restore-files-upgrade-windows-old

For issue about "no explorer", press Ctrl-alt-del, then launch Task Manager\File\Run new task, then type explorer.exe, OK. are you able to get the desktop and explorer now?

Ok so it happened again

I dont know why I tried explorer.exe with and without admin privs

from cmd and taskmgr I hope microsoft makes an update for this

BTW It kept all my files and all after the upgrade

Wait is there a boot menu for windows 8.1 like 7 because I pressed F8 and did not get anything so how do I do last known good config

I tried sfc /scannow it fixed files restarted my computer

and it happened again logged in for a few seconds logs off lock screen picture not there profile picture gone log in and what do I get a BLANK screen

Keep pressing F8 during boot up. Its the same as you get in Win 7

Really I tried multiple timesbefore I did not get it 

I will try again

I could not get the boot menu

I upgraded windows 8 pro with MC to Win 8.1 pro with MC

all the windows files and my files are missing I can not go to the start desktop is blank no explorer what should I do

The desktop is blank ? No task bar as well?

Btw, what options did you select while upgrading to Win 8.1 ? We get 2 options, one to keep files and other one to fresh install. 

I am not sure it was an update from store

I was gone for a while when I came back I did all the agreeing and what not then it restarted my profile picture was gone nopo explorer I tried control alt del ran taskmgr I am really mad

Reboot the system in Last known good configuration and check the results. 

You can enter the advanced boot option in Windows 8.1 by click "Change PC settings"\Update and recovery\Recovery\Advanced startup, then restart, you will get a shell menu to choose a startup mode, you can choose "Troubleshooting"\Advanced Options\startup settings...

I also suspect that this might be related with a corrupted user profile, have you test in another account? You can create a new account, and test if this issue persists.

explorer is working

I went to PC settings to do a refresh it said windows files are missing and insert recovery or installation disc but I do not have these because the update was from the store

what should I do

explorer is working

I wonder how?  Others are having a problem with ieframe.dll specifically.

C.f.

Oh, yeah and an incorrect version of dism.exe.  How do these things happen?

What about  sfc.exe  /scannow   from a Command only boot?

oh yes I tried sfc /scannow on admin command prompt it said it fixed files but the problem happened the only thing I can think of is to get some recovery disc to refresh or never turn off the PC

Is there a way I can get some recovery disc or something

The suggestion to get into the Advanced boot options menu was a good one.  Since you can start Task Manager (e.g. Ctrl-Alt-Delete) you can use it to do a shutdown.exe /r /o (e.g. in the More details view use the File Run... command to do that.)  I'm not sure if you need to do it elevated but that would be possible there too.

 
Good luck
