FIX: Store Apps or Files Missing after Windows 10 Update 1709 (Solved)

Last updated on February 7th, 2018

The following issue is occurred on a customer's computer, after installing the Windows 10 Fall Creators Update (v1709): Windows displays the error "We can't sign into your account" after sign-in and all the user's  personal files and the installed Store Apps are missing. After investigating the problem, I discovered that Windows 10, during the update, has created – for unknown reasons – a new temporary profile and then loads this profile as the default profile for the user. Yes, it is another Windows 10 bug and the update should be renamed to "FAIL Creators Update" Smile

Part 1. How to Fix Corrupted Profile in Windows 10.

First of all check if your missing personal files are located on another location on the drive "C:". To do that:

1. Open Windows Explorer and navigate to "C:\Users\" folder and see if your personal files exists there.  Inside the "C:\Users" folder, explore one by one all the listed folders (except the "Public" folder) and their subfolders, until you find out which one contains your personal files. (Documents, Pictures, Videos, etc.). *

Note:  Commonly the personal files, for each user account can be found under the "C:\Users\%AccountName%" directory. (e.g. If your account name is "Admin" then look inside the "C:\Users\Admin" folder to find your files).

2.  If you can see your  personal files at the "C:\Users\%AccountName%" folder, then continue to the steps below to restore your personal files and settings back.

3. If you cannot find your files at the "C:\Users\%AccountName%" folder, then explore the contents of  "C:\Windows.old\Users\%AccountName%" directory. If you can find your files there, then the only ways to restore your apps and files, is to restore Windows 10 to the previous version or to transfer your personal files from the "C:\Windows.old\Users\%YourAccountName%" folder to you current profile folder "C:\Users\%YourAccountName%" and then to reinstall all the programs and apps from the begging.

Step 1. Enable the Hidden Administrator Account

1. Open Command Prompt as Administrator. To do that:

a. In the Search box type: cmd (or command prompt).
b. Right click on the command prompt (result) and select Run as Administrator.

run command prompt as administrator


2. Inside the command prompt window, type the following command and press Enter:

  • net user administrator /active:yes

Enable Administrator account


3. After that you should view a message that says that your command was completed successfully.
4. Close Command prompt.


Step 2. Modify User Profile Settings in Registry.

1. Sign Out from the current account and Sign-In as Administrator.
2. Open
Registry Editor. To do that:

1. Simultaneously press the Win image + R keys to open the run command box.
2. Type regedit and press Enter to open Registry Editor.

6. In registry editor, double click at "ProfileList" key to expand its contents.

7. Now, under the ‘ProfileList’ registry key you should see two (or more) subkeys named "S-1-5-21" followed by a long number (e.g. ‘S-1-5-21-1001432958-3492499226-3494023764-1001).

8a. Click each "S-1-5-21-xxxxxxx" subkey and look at the right pane, at "ProfileImagePath" value to find out which "S-1-5-21-xxxxxxx" subkey shows the path for your old profile, which contains your personal files and folders.

8b. Once you find which "S-1-5-21-xxxxxxx" subkey, contains the path (location) for your files, select it on the left pane and Delete it. *

* For example, lets suppose that your account name is "Admin" and your personal data are located at the "C:\Users\Admin" folder.

9a. Now find which "S-1-5-21-xxxxxxx" subkey, has the value "YourAccountName.YourComputerName" * on the ProfileImagePath.

* e.g. At this example the account name is "Admin" and the computer name is "DESKTOP-I238D3P", so the value data on the ProfileImagePath key is "C:\Users\Admin.DESKTOP-I238D3P".
