If you can\u2019t install the latest updates for your system via the Windows Update utility because you keep seeing the error code 0x800f0845, the solutions in this article will help you get rid of the error.<\/p>\n
The Windows Update Troubleshooter is a dedicated tool that checks for glitches affecting the Windows Update utility. It will go over the services related to Windows Update and try to resolve any application conflicts that might be preventing the tool from running properly. Once you run the Troubleshooter, it will tell you what errors have occurred and allow you to apply the necessary fixes if they are available.

To resolve the problem, in this case, you have to run the System File Checker tool to find missing or corrupted system files and replace them automatically.<\/p>\n Since you’re using Windows 10, you will have to run the inbox Deployment Image Servicing and Management tool before you run the System File Checker. The job of DISM is to provide the files that will be used to replace the problematic ones.<\/p>\n The following steps will show you how to run DISM and SFC:<\/strong><\/p>\n The command will prompt the DISM tool to fetch the repair files, using the Windows Update utility.

You can also mount a Windows 10 ISO file as a virtual DVD and use it as the repair source.

Try scanning your computer and check if that has resolved the problem.<\/p>\n It is important that you run a full scan instead of allowing your antivirus program to run the regular quick scan. The full scan will scour different corners of your system and make sure no stone is left unturned. You can easily go to the Scan menu of your antivirus program to initiate the full scan.
