If you encounter error 0x800f0954 when installing optional Windows features, it may be because your system is unable to access the Windows Update server. This is especially true for domain-joined computers that are configured to download updates from a WSUS server. It’s also possible that your computer was once part of a domain or corporate network and the Group Policy settings are still there. The same error can occur when trying to install additional speech recognition or additional fonts using optional features on the Settings page or using the DISM command line.
