Here are some guidelines to follow if you receive error 0x800f0805. While activation problems are easy to resolve, update errors can be more complicated to resolve.
What causes the product key error 0x800F0805?
- Damaged or missing system files: Improper installation of the operating system can cause this, which in turn leads to this error. System files are important to ensure that your device works properly. Sometimes system files get corrupted or deleted, which can cause Windows license/update installation to fail. Another reason may be corrupted areas of your hard drive that may be infected with viruses and malware.
- Not enough disk space: If this error code is associated with a Windows update installation error, there is a possibility that the Windows drive (default C drive) does not have enough space to install Windows updates, which eventually leads to this error. Before looking for a solution, make sure you have at least 16 GB and 20 GB of free space on your C drive for 32- and 64-bit versions of Windows 10, respectively.
- Poor Internet connection: Obviously, the Windows update/license installation process will display errors if you do not have an active Internet connection (good bandwidth). Limited Internet access despite having an Internet connection indicates that the problem is with your Internet connection and not with the Windows upgrade/installation key.
- Update installation error: In rare cases, the Windows update installation error is due to errors in the updates supplied to your computer. This indicates that there is no problem with your system, but Microsoft’s servers are having problems due to errors.
- Outdated drivers: Drivers are needed to run components not originally compatible with Windows 10, such as video cards, network cards, etc. If the driver has not been updated for some time, this may cause problems with Windows Update.
- Major programs/processes: Some applications run automatically in the background, such as antivirus software and major system processes when you start your computer. These services can prevent you from updating Windows to the latest version or installing Windows updates, which ultimately causes errors.
