How to recover missing files after an upgrade on Windows 10

The setup process to upgrade to Windows 10 from a previous release, or from a previous version (such as Windows 8.1 or Windows 7), usually does a pretty good job preserving your files. However, in some scenarios, unexpected behaviors may occur that will cause your documents, pictures, music, and videos to suddenly disappear after the installation.

If this happens, not everything is lost just yet, as there are a number of ways to find and restore missing files.

In this Windows 10 guide, we'll walk you through a few ways you can get back your documents, pictures, music, and videos after upgrading to the latest version of the OS.

How to recover files removing temporary account

Immediately after upgrading to the latest version of Windows 10, you may notice that your files are no longer available, but this is because you're signed in using a temporary account.

You can quickly check if you're using a temporary profile using these steps:

  1. Open Settings.
  2. Click on Accounts.
  3. Click on Sync your settings.

  1. If you see a message at the top that reads: "You are logged on with a temporary profile. Roaming options are currently unavailable," then reboot your computer.Note: It may take a few reboots until you see your account on the sign-in screen.
  2. Sign in with your account.

Once you've completed the steps, the temporary account should go away, and you should now be able to access your documents, pictures, and videos from your original account.

How to recover files using Administrator account

If you're upgrading from Windows 7 to Windows 10, and you created a Microsoft account during the process, your files may end up in the Administrator account, which is now disabled.

To get back your missing personal files, you'll need to use the built-in local Administrator account using these steps:

  1. Open Start.
  2. Search for Computer Management, click the top result to open the experience.
  3. Browse the following path:Computer Management > Local Users and Groups > Users
  4. Double-click the Administrator account.

  1. Click the Account is disabled option.
  2. Click Apply.
  3. Click OK.

  1. Sign out of your current account.
  2. Sign in with the Administrator account.

After completing the steps, you should see your files again using the local Administrator account. Then the last thing left to do is to backup and restore all your files to the newly created account you configured using a Microsoft account.

How to recover files using search

You can also locate lost files using the search feature on Windows 10 with these steps:

  1. Open File Explorer (Windows key + E).
  2. On the left pane, click the This PC option.
  3. On the top-right, use the search box to locate your files.

If you're looking for a specific type of files, you can use the asterisk (*) as a wildcard. For instance, you can use the *.doc search query to list all of your Microsoft Word documents.

Also, you can use the File Explorer Search tab options to refine your search. For example, you can click the Advanced options drop-down menu and make sure to include non-indexed locations. In addition, you can use the Kind drop-down menu to do quick searches, including for documents, pictures, videos, music, and more.

When upgrading to a new version of Windows 10, sometimes your personal files will move to a different folder. If you're able to find your files using search, right-click one of the files and select Open file location, and then make sure to move your data to the folder you want.

Show hidden files

Depending on your system configuration, you may not be able to see your files because they're hidden. On Windows 10, you can see hidden files using these steps:

  1. Open File Explorer.
  2. Click the View tab.
  3. Under "Show/hide section," check the Hidden items options.

After completing the steps, try to use the search feature again to find your files.

How to recover files using Windows.old folder

If you installed Windows 10 using the upgrade process, or you went through a custom installation without deleting the main partition, then the setup will save a copy of your previous installation in the Windows.old folder, which you can use to recover your missing files.

To recover your files using the Windows.old folder, do the following:

  1. Open File Explorer.
  2. On the left pane, click the This PC option.
  3. Double-click the Local Disk (C:) drive.
  4. Double-click the Windows.old folder.

Once you've completed the steps, locate your personal files (likely to be stored in the "Users" folder), and move them to another location.

If you don't see the Windows.old folder, you may have upgraded using the clean installation process which erases everything on your computer. Something may have happened during the installation and copy of the previous installation was never saved. Or it's been more than 10 days since you upgraded to Windows 10, in which case the system deletes these files automatically.

How to recover files using backup

If none of the methods outlined above have worked to get back your lost files, then you'll need to use a previous backup to recover them. But bear in mind that the steps may vary depending on the backup method you used.

Below you'll find the steps to recover your files when using the built-in system tools and OneDrive. (If you used another tool, make sure to refer to your software vendor support site for specific instructions.)

Using System Image backup

If you used the System Image backup tool built into Windows 10, you won't be able to restore files individually, but you can connect the external drive with the backup files and then use this workaround:

  3. Browse the following path:Storage > Disk Management
  4. Click on Action.

  2. Select the largest VHDX file.

  1. Click Open.
  2. Click OK.
  3. Right-click the partition, and select the Change Drive Letter and Path option.

  1. Click the Add button.
  2. Select a drive letter. (Typically, you want to use the one that's already selected.)

  1. Click OK.

Once you've completed the steps, open the drive using File Explorer, locate and copy your files to your computer.

It's a good idea to right-click the virtual drive, select the Detach VHD option when you're done copying the files to properly remove the virtual hard drive.

Wrapping things up

Although the upgrade process is capable of keeping your files, it's important to acknowledge that there's always a chance that something wrong may happen. This is why it's really important to regularly create a backup of your data (at least before proceeding with an upgrade) in cases such as this one.

In addition, a backup is not only good to get your files back after an upgrade, but it can also help you recover from a hard drive failure, or after a malware infection.
