Third-party apps may add a small metadata header (e.g., BAK1.0 ) to the file. WhatsApp’s decryption routine expects a pure crypt12 header (12 bytes of salt + IV). If that header is damaged, the restore will fail with an "unable to restore" error.
Yes, using third-party forensic tools, but with significant caveats.
When manually copying msgstore.db.crypt12 to a PC or cloud storage, always keep the original extension. Do not let backup software auto-rename.
You must take ownership of the WindowsApps folder as it is restricted by default.

Uninstall WhatsApp completely, then reinstall it from the Play Store. When prompted to restore from Google Drive, skip that option. Instead, WhatsApp should automatically detect the local msgstore.db.crypt12 file and offer to restore it.
Demystifying WSAppBak: The Ultimate Guide to Backing Up and Repacking Windows Store Apps
Microsoft has officially dropped store support for older operating systems like Windows 8, 8.1, and early builds of Windows 10. Consequently, many classic Metro-era games and utilities have been removed from the live servers. Users who still have these apps installed on working hardware use WSAppBak to extract and preserve them before the local machines are wiped or decommissioned. Sideloading and Custom Deployment Third-party apps may add a small metadata header (e
Modern versions of Microsoft Windows download applications via the Microsoft Store into a heavily restricted system folder known as WindowsApps . This folder is guarded by complex Access Control Lists (ACLs) and SYSTEM-level ownership protections, preventing standard copy-and-paste backups.
If the file is a database, it often needs to be renamed back to msgstore.db.cryptXX and placed in the /WhatsApp/Databases/ folder for the app to recognize it.
When you run a “cleanup” or “duplicate finder” app, the tool scans for large .crypt12 files. Some of these apps (particularly older versions) do not recognize the .crypt12 extension. To prevent accidental deletion, they rename the file to a neutral extension—like .wsappbak —and move it to a folder such as ./backups/temp/ or ./WhatsApp/Backups/Manual/ .
However, WSAppBak is not a magic bullet. Compatibility issues exist, and the repackaging process does not always succeed. Alternative methods—particularly direct APPX downloads from store.rg-adguard.net —are often simpler and more reliable when they work. Yes, using third-party forensic tools, but with significant
Note: You may need to take ownership of this folder to access it.
: It automates the process of identifying installed application files, extracting their metadata, and recompiling them into a distributable .appx format.
Some adware trojans rename database files to .wsappbak to trick users into ignoring them, then request unnecessary permissions. Run a scan with or Bitdefender if wsappbak files appear outside of expected backup folders.
