Frequently Asked Questions

Files that appear missing after an update may be in a different user profile, cloud folder, or previous Windows installation. Search those locations before installing recovery software.

Check What Changed During the Update

Sign in to the same account used before the update and search for filenames. Check Documents, Desktop, OneDrive, and any other profiles. If the update was a major upgrade and Windows.old exists, inspect its user folders promptly.

Windows.old is not guaranteed to exist and can be removed automatically after the rollback period. Do not perform another reset or reinstall as a way to look for missing files.

Protect the Original Storage

Copy any located files to a separate drive. Check File History and cloud version history before scanning; those copies may be complete.

If files are truly absent from local storage, reduce new writes to the system disk. Prepare another physical device for recovered output.

Scan Only for Genuinely Missing Local Files

Qiling Deep Data Recovery provides a visual scan of storage that Windows can detect. In this case, a scan is appropriate only after checking the account, Windows.old if present, and backups. A listed file is only a candidate until you open and verify its recovered copy.

Step 1. Search Existing Windows Copies

Inspect active and prior user folders, OneDrive, Recycle Bin, backups, and Windows.old if it exists. Record the former file path.

Step 2. Choose a Loss-Specific Mode

Use Fast Scan for recent deletion on an accessible volume. If an entire partition is missing after the update, Disk Scan may be more relevant, but stop if the disk is unstable.

Step 3. Select the Pre-Update Disk

Choose the physical disk that held the files, verifying capacity. Do not scan a newly connected backup drive by mistake.

Step 4. Inspect Dates and Contents

Filter for known file types and preview candidates. A file with an old name may be an older version, not the state immediately before the update.

Step 5. Recover to Another Device

Click Recover for useful results and save to another disk. Open and compare them with any Windows.old or cloud copies.

Keep the Best Copy

Choose the most complete verified version from backups, cloud, Windows.old, or scan results. Avoid copying a partial result over an intact earlier version.

For future major updates, make a verified backup first. An update rollback facility is not a substitute for a personal-file backup.

Frequently Asked Questions

Does every Windows update create Windows.old?

No. It depends on the type of update and installation; check whether the folder actually exists.

Can another update restore deleted personal files?

Do not rely on it. Search existing copies and protect the disk from more writes.

Should I scan if the files are visible under another account?

No. Copy accessible files after confirming ownership; a deleted-file scan is unnecessary.

If the files disappeared after rolling back a Windows 11 upgrade, follow the upgrade rollback file-recovery checklist to check profile folders and backups before scanning.
