What causes the DISM source files could not be found error?

For users who have encountered this error, there are a few known causes. These include:

Internet issues – If the DISM service can not establish an internet connection, you should expect the command to fail and trigger some error codes. Corrupted system files – If, for instance, your install.wim file is bad or corrupted, you will have issues running the DISM command. File duplicates – Once again, the install.wim file duplicated in the exact location may trigger this error. You will need to do some house cleaning to get rid of it.

Even though the main body of this error message is the same, the code for the error might differ: Here are a few possible options:

0x800f081f – In this instance, the OS has been unable to locate the .NET source file needed for an installation to proceed. 0x800f0906 – The DISM command cannot locate files needed to fix other harmful files. 0x800f0907 – It implies some system files critical to an update are missing.
