The esent.dll file is the Extensible Storage Engine Runtime in Windows. It manages internal databases for system search, Windows updates, and user profiles. Errors usually happen due to registry corruption, malware, or failing system files.

Here is how to fix it without downloading anything from the internet.

1. Run SFC and DISM Tools

Windows has built-in repair tools that automatically replace missing or corrupted system files like esent.dll using safe, local copies.

Press the Windows Key.
Type cmd.
Right-click Command Prompt and choose Run as administrator.
Type sfc /scannow and press Enter. Wait for the scan to finish.
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
Restart your computer.

2. Re-register the DLL File

If the file exists but Windows cannot read it, you can force the system to register it again in the database.

Open Command Prompt as administrator (same as step 1).
Type regsvr32 %systemroot%\system32\esent.dll and press Enter.
Click OK on the confirmation popup.
Restart your PC.

3. Check for File System Errors

A corrupted hard drive sector can make esent.dll unreadable. You can use the Check Disk tool to repair it.

Open Command Prompt as administrator.
Type chkdsk c: /f /r and press Enter.
Type Y when asked to schedule the scan on the next restart.
Restart your computer and let the scan finish.

4. Use Windows System Restore

If the error started recently, you can roll back your system configuration to a time when it worked perfectly.

Press Windows Key + R to open the Run box.
Type rstrui and press Enter.
Click Next and choose a restore date before the error started.
Click Finish and wait for the process to complete.
