How to Recover Deleted Files After Windows 11 26H2 Update?

Can the Windows 11 26H2 Update Delete Your Files?

No, not under normal circumstances. Installing Windows 11 26H2 is designed to keep your personal files. The update itself should not erase documents, photos, videos, or other personal data.

If files are missing after the update, it's not necessarily mean that they are permanently deleted. In many cases, the files still exist but are no longer visible in their usual location. Microsoft documents several cases where users may have trouble finding their files after upgrading Windows.

For example, your files may appear missing if:

• Windows signs you into a temporary or different user profile.
• Your files are stored under another user account.
• OneDrive changes where Desktop, Documents, or Pictures files appear.
• Previous files remain in the Windows.old folder.
• A file was accidentally deleted before or after the update.
• The update process was interrupted by a system or storage problem.

The key is to determine whether the files are only missing from their usual location or are actually deleted.

Why Are Files Missing After the Windows 11 26H2 Update?

Files can disappear from their usual locations for several reasons. The Windows 11 26H2 update itself is not always the direct cause. Here are some common situations:

Since many of these cases do not involve permanent deletion, check the file locations first. Use recovery software only when normal checks and backups cannot restore the files.

What to Do First If Files Are Missing After Windows 11 26H2 Update

Start with simple checks before attempting data recovery. Your files may still exist on the drive or in your cloud storage.

Method 1: Search for the Missing Files

The Windows 11 26H2 update may not have deleted the file. It may simply be in a different folder. Try searching for it first:

• Open "File Explorer", select "This PC" to search across your local drives, and type the file name in the search box.

• If you do not remember the full name, search by part of the name or file extension, such as .docx, .jpg, or .xlsx. When a result appears, check its location and the common Desktop, Documents, Downloads, Pictures, and Videos folders.

• If you find the file, copy important data to a safe location before making more system changes.

Method 2: Check the Recycle Bin

If a file was deleted recently, it may still be in the Recycle Bin.

• Double-click "Recycle Bin" on the desktop, look for the missing files or folders, and sort them by "Date Deleted" if needed.

• Right-click the file you want to recover and select "Restore". Windows will return the file to its original location.

  

If the Recycle Bin is empty or the file was permanently deleted, move to the recovery options later in this guide.

Method 3: Check OneDrive and Your User Folders

OneDrive can back up or sync common Windows folders, including Desktop, Documents, and Pictures. A file that appears missing locally may still be stored in OneDrive.

Open OneDrive and check:

• Desktop
• Documents
• Pictures
• OneDrive Recycle Bin

Also check C:\Users\YourUserName, including Desktop, Documents, Downloads, Pictures, and other folders. If more than one user folder appears under C:\Users, check the other folders as well because your previous files may still be stored under another Windows profile.

Method 4: Check the Windows.old Folder

If the Windows upgrade created a Windows.old folder, some files from the previous Windows installation may still be available there.

Microsoft states that files stored in Windows.old are normally available for only "10 days after an upgrade". After that period, most Windows.old content is automatically deleted. To check it:

• Open "File Explorer", go to "This PC > Local Disk (C:)", and open "Windows.old > Users".

  

• Select your previous user account folder and check Desktop, Documents, Pictures, Downloads, and other personal folders.

• Copy any needed files to your current user folder or another safe location.

Do not move or delete the entire Windows.old folder manually.

Method 5: Check Whether Windows Signed You Into a Temporary or Different Account

A temporary user profile can make your Documents and Desktop folders look empty even though your original files still exist. Microsoft recommends checking your account if files disappear after a Windows upgrade.

• Go to "Settings > Accounts" and check whether Windows reports that you are signed in with a temporary profile. You can also look under C:\Users for your normal account folder.

• If Windows loaded a temporary profile, save any new files created during that session to an external drive.

• Restart the computer, sign in to your normal account, and check Desktop, Documents, Pictures, and other folders.

You may need to restart the PC more than once. If the files are still missing after these checks, they may have been deleted or become inaccessible.

How to Recover Lost or Deleted Files After Windows 11 26H2 Update?

If the files are no longer available, choose a recovery method based on whether you have a backup.

Method 1: Restore Files from an Existing Backup

If you have a File History or OneDrive backup, restore the backup copy before using data recovery software. This is usually the safest option because it does not require scanning the affected drive.

If File History was enabled before the file was lost:

• If your File History backup is stored on an external drive, connect that drive. Then search for "Restore your files with File History" from the Start menu.

  

• Open the recovery window, browse the available backups, and locate the missing file or folder.

• Select the item and choose "Restore" to return it to its original location.

If the file was synced to OneDrive, sign in to OneDrive and search for it.

Method 2: Recover Files Without a Backup Using 4DDiG

If you do not have a usable backup, 4DDiG Data Recovery can scan the affected drive for lost or deleted files. It supports common file types such as photos, videos, documents, audio files, and archives.

You can use 4DDiG when files disappear after a Windows update, system crash, accidental deletion, formatting, or other data-loss situations. Its advanced scan mode can search more deeply for files that are no longer visible or accessible in Windows.

• Download and install 4DDiG. If possible, install it on a different partition from the one containing the lost files. Launch 4DDiG and select the drive or partition where your files disappeared after the Windows update.

  

• Start scanning the selected drive. While the scan is running, filter the results by file type, such as documents, photos, videos, audio files, or archives, to locate the files missing after the update.

  

• Preview the files found by 4DDiG to confirm that they are the versions you need. You can also search by file name or check the original file path when that information is available. Select the required files and click "Recover".

  

• Choose a different drive or storage device as the destination, then click "Save Now". Do not save the recovered files to the affected drive because doing so may overwrite other recoverable data.

  

Method 3: Use Windows File Recovery as a Command-Line Alternative

Windows File Recovery is Microsoft's command-line tool for recovering deleted files from internal drives, external drives, and USB storage devices. It does not recover files from cloud storage or network shares.

This option is more suitable for users who are comfortable with recovery commands and do not need a visual file preview.

• Install Windows File Recovery from the Microsoft Store and connect another drive for the recovered files.

• Open Windows File Recovery and use the following command format:

  winfr source-drive: destination-drive: /regular /n path-to-file-or-folder

  For example, to recover files from the Documents folder on drive C: and save them to drive E:, run:

  winfr C: E: /regular /n \Users\YourUsername\Documents\
  

• Press Y if prompted to start the recovery. When the process finishes, open the destination drive and check the recovery folder for your recovered files.

The source and destination drives must be different. If you are unfamiliar with command-line tools or need to preview files before recovery, a graphical recovery tool like 4DDiG may be easier to use.

Can You Recover Files with Point-in-Time Restore?

Yes, Point-in-time Restore may recover files that existed when the restore point was created. However, it restores the entire PC state, including Windows, applications, settings, and local files, rather than recovering selected files.

When enabled, Point-in-time Restore normally creates a restore point about every 24 hours and retains it for approximately 72 hours. The restore points are stored locally on the PC.

The following comparison can help you choose the appropriate recovery option:

Point-in-time Restore is better suited to broader system problems after a Windows update. Because it rolls back the entire OS volume, applications, settings, and local file changes made after the selected restore point may be lost.

If you only need a few files, use File History, OneDrive, Windows File Recovery, or data recovery software first. Point-in-time Restore does not let you mount a restore point and recover selected files individually.

How to Prevent Data Loss Before Updating to Windows 11 26H2?

A Windows update should normally preserve your files, but keeping a backup gives you another recovery option if something goes wrong. Here're a few tips to follow.

• Back up important personal files: Save important documents, photos, videos, and project files to OneDrive or an external drive.
• Keep enough free storage space: Low disk space can cause update and recovery problems.
• Keep the PC connected to power: Avoid interrupting the update while Windows is installing files.
• Check OneDrive sync status: Make sure important cloud files have finished syncing before starting the update.

FAQs About Windows 11 26H2 File Recovery

Does Windows 11 26H2 delete files?

A normal Windows 11 26H2 update is designed to keep your personal files. If files appear missing afterward, first check your user profile, OneDrive, Recycle Bin, Windows.old, and other common folders. If the files cannot be found in these locations or in a backup, file recovery may be necessary.

Where are my files after the Windows 11 26H2 update?

Start by checking Desktop, Documents, Downloads, Pictures, OneDrive, and C:\Users. Also check whether Windows signed you into a temporary or different account. If Windows.old exists, check C:\Windows.old\Users for files from your previous installation.

Can I recover permanently deleted files after updating Windows 11?

Possibly. If the deleted data has not been overwritten, Windows File Recovery or data recovery software may be able to recover it.

Does rolling back Windows 11 26H2 restore deleted files?

Not necessarily. Rolling back a Windows update is designed to return Windows to an earlier version. It should not be treated as a reliable way to recover deleted personal files.

Conclusion

If files are missing after the Windows 11 26H2 update, first confirm whether they are actually deleted. Search your PC and check the Recycle Bin, OneDrive, user folders, Windows.old, and your Windows account.

If the files are truly lost, restore them from File History or OneDrive when a backup is available. Windows File Recovery and 4DDiG File Recovery can provide additional recovery options when no usable backup exists.
