After update of my windows 10 I got problem Desktop is unavailable

Yes this works , thanks . My error messages were "C:\Windows\system32\config\systemprofile\Onedrive\Documents is unavailable.If the location is ...."

Additional messages noted with Word -mso1033.acl error , unable to save file , 

Excel messages noted "microsoft excel cannot open or save any more documents because there is not enough available memory..........."

For what its worth - also observed that

all of a sudden right click did not pop up the menu including shut down or sign out .

my screen fonts were not he usual sharp ones - seemed dotted

Unfortunately the revised installation does not work. After 30% of download installed the installation ceases.

Having taken a week trying to resolve this and getting nowhere a complete recovery was the only action open to me. This I have done and I am now re-installing all of my lost programmes and data, BUT I AM NOW SEEING PROGRESS NOT JUST WASTING TIME. Thank you Microsoft for nothing.

This work for 2 computers that had Avast antivirus on them.  Might not work for everyone, but all the files came back.  Good luck....

What solution are you taking about  There are over one thousand comments so trying to find it in one of them is...well...no. Lol

Things you will need:

8GB or larger blank USB stick

a functioning Windows PC to use briefly

about an hour or two of spare time

Steps:

1. Turn on the problem computer.
2. At the blue screen, choose your language. 
3. Choose “Use another operating system”. 
4. Choose the second option, “Windows 10 on volume [x]” 
5. Wait for the computer to boot to the desktop (if necessary, enter your password to login). You may have to wait a long time for the desktop to appear, while the “update” gets ready.
6. Once the desktop attempts to load, close any error message that appears.
7. On a functioning Windows PC, go to www.microsoft.com/en-us/software-download/windows10.
8. Click “Download tool now”. Disable any antivirus on the functional PC before proceeding to step #9.
9. Run the tool you downloaded, and follow the simple steps to create a Windows 10 installation USB stick (on your BLANK USB drive). The only option you should check is to make sure it is a 64-bit or 32-bit version. Your computer is MOST LIKELY 64-bit, and if you install the 32-bit version when you don’t need it, you’re probably going to have a bad time.
10. On the problem computer, right-click the taskbar, then click “Task Manager”.
11. Click “More details” so that you can see the menu bar. 
12. Click “File”.
13. Click “Run new task”. 
14. In the dialog that appears, check the box “Create this task with administrative privileges”.
15. Click “Browse…”
16. Navigate to your USB drive and select “setup.exe”.
17. Run the file and follow the steps to “upgrade” Windows. Uncheck the boxes for “check for new updates” and to “help make this version better”.
18. Let the process run, which may take some time. Once completed, the computer should be back to normal, and fully up-to-date. You may need to re-login to your Microsoft Account.
19. While it is not necessary to remove your third-party antivirus software, we’d recommend that you remove it anyway, given that it likely caused the issue. Windows Defender is built in to Windows 10, is free of charge, and is quite adequate for consumer-level protection.
