PC stuck at a blurry login screen

I trusted. It does not work.

I have this problem. Nothing listed is working. This is a Microsoft caused problem and I hope you are sued in a class action lawsuit for disrupting my work.

Safe mode and navigating to local account and system profile account and deleting cashes worked. I also went into setting users and created an new user and rebooted it worked. I then used a usb flash and upgraded to the latest version.  All seems ok again.

***FIX***

Initial Steps (Enter Recovery Environment):

1. Enter Recovery Environment (If you are unable to get into the recovery environment via a menu, you can turn off your system during the initial boot when the Windows logo is on the screen and the dots are circling. Do this at least twice and you'll see the message "Starting Automatic Repair").
2. Once the recovery environment loads select "See advanced repair options", then "Troubleshoot", then "Advanced options".

Method #1 (Via Command prompt - assumes basic command prompt knowledge):

1. Click "Command Prompt".
2. Change directory to your boot drive if necessary (for example, type c: and press <ENTER>)
3. Type "CD %windir%\system32\config\systemprofile\appdata\local\microsoft\windows\caches <ENTER>
4. Type "DIR <ENTER>" and make sure you are in the right path. You should see one or more .db files -- usually just cversions.3.db. If there are no files in this directory see the addendum below.
5. Type "DEL *.* <ENTER>"
6. Reboot and test

Method #2 (Via Safe Mode and File Explorer - may require adjusting permissions):

1. Click "Start-up Settings" and "Restart" to reboot the system and get the option to enter Safe Mode.)
2. At the Startup Settings screen press "4" to boot in Safe Mode.
3. Log into your administrator-level account.
4. Open File Explorer and browse to**%windir%\system32\config** (example: c:\windows\system32\config)
5. Gain access to systemprofile (you may be able to just double-click it to gain access)
6. Drill down to**%windir%\system32\config\systemprofile\appdata\local\microsoft\windows\caches**
7. Delete all files inside caches
8. Reboot and test

Addendum

Some have reported that it is necessary to clear the caches folder of the local user account also or instead of the systemprofile account. If the above procedure does not work for you, delete the file(s) in the local user cache folder (located in %localappdata%\microsoft\windows\caches) using either Safe Mode or the recovery environment command prompt.

Good luck!

Special thanks to John_E_M for first suggesting the localappdata caches folder, and to Artaeos who also narrowed down the problem to the systemprofile caches folder at the same time I did. Great job guys!

This solution worked for my Dell Inspiron 7000 series. It was a pain getting windows to go into the recovery mode (before you go to Method 1 or 2). A better explanation of that can be found on https://support.microsoft.com/en-ie/help/12376/windows-10-start-your-pc-in-safe-mode

After following the steps to go into the recovery, following Method 2 helped. I also deleted the cache files mentioned in the addendum. I left the ones that weren't getting deleted as it is.
