Reset the SoftwareDistribution and Catroot2 folders
You must delete the contents of the SoftwareDistribution folder. All update files are downloaded to the Software Distribution folder, which is located in C: \ Windows \ SoftwareDistribution. First, delete all the files it contains after stopping Windows Update services. Second, try restarting your computer a few times to see if the update process starts automatically.
You should also reset the Catroot2 folder, which stores Windows Update package signatures and makes installation easier.
Clear temporary files
You’ve probably heard (or tried) the rollback option available in the recovery menu. Windows 10 actually keeps the installation of the previous version so you can reboot your system if something goes wrong. On paper, that’s great. However, some users have suggested that clearing these and other temporary files might fix error 0x800f0900.
To run Disk Cleanup and remove any redundant files:
- Open this computer or explorer.
- Right click on the section where you want to delete unneeded data and open Properties.
- Click Disk Cleanup.
- Select the option to Clean up system files.
- Check all the boxes and click OK.
Perform a clean install
If none of the previously recommended steps helped, a clean reinstall is the only viable solution. Here we have explained the whole process. It doesn’t take long and you can still save your data. Of course, you need to back up the files from the system partition to an additional partition or external drive. The bootable USB drive created with the Media Creation Tool in the previous step should be sufficient to reinstall the system.
