What Is Spreview?

Spreview is a Microsoft program that exists as an executable file, Spreview.exe. The genuine file is a component of the Microsoft Windows Operating System by Microsoft Corporation. The file is installed on a Windows system during the installation of a Service Pack from Windows Update.

– Is Spreview Safe?

A genuine SP is a safe file and not a virus. The executable file installs as C:WindowsSystem32SPReviewspreview.exe, where C represents the operating system drive. This installation also sets a registry key in HKEY_USERS.DEFAULTSoftwareMicrosoftWindowsCurrentVersionRunOnce and its HKCU counterpart.

The program loads once and will present a message that the SP has been installed at the next boot only. This is normal rebooting after the installation of the Windows Service Pack.

If the reboot is successful, the RunOnce key is deleted, and “SPReview.exe” is removed. Nevertheless, if the message appears repeatedly, it means reboots since the installation was unsuccessful.

SPReview is the short form for Windows Service Pack Installation Reviewer and is referred to as sp reviewer.

Note that SP is a program that is a part of the installation which acknowledges the installation of the service pack on your computer. Deleting any files within the ‘System32’ folder is not recommended, as they are system files.

The program is recognizable on the Task Manager and as a window. Microsoft itself digitally signs the genuine file to guarantee its authenticity. Therefore, experts largely regard it as a safe file.

However, this file has variants, and such variants are usually malicious. Besides, an outdated file can affect how your computer functions.

You can quickly check whether the file you have is legit. Here is how to check whether the file is safe:

  1. Launch the Task Manager.
  2. Click View and then Columns.
  3. Choose “Image Path Name” to add a location column. If you see any suspicious directory, investigate that process further.
  4. Add Verified Signer to one column.
  5. Check the Verified Signer value; if it reads Unable to verify, it could be a virus.

SPReview.exe Issues

Some spreview.exe errors occur when the file is loading, either at startup or when it is already running. These are commonly called runtime errors. Note that runtime errors are pretty common when using Windows. Therefore, you should know how they present themselves and how you can fix them.

More often, spreview.exe runtime errors that occur while the program runs will terminate the program abruptly. Typically, these spreview error messages mean that Microsoft Windows could not locate this file on startup or the file is corrupt. This results in a prematurely-aborted startup process.

  • Spreview.exe – Bad Image.
  • Spreview.exe could not be found.
  • Spreview.exe Application Error.
  • Spreview.exe could not be installed.
  • Cannot find spreview.exe.

In some instances, these errors could be due to malware infection, which corrupts files. So, it is vital to ensure that you regularly scan your system.

Finding the source of a spreview error is critical in effectively solving the errors. Those errors occurring at runtime, i.e., while using MS Windows OS, could be due to:

  • Poor programming by Microsoft Corporation.
  • The file conflicts with third-party software or another software.
  • You have accidentally deleted or moved a file.
