3 .dll files are missing, can't find it on the internet

Hey, i have Windows 8.1 x64 on my PC.

Many programs don't work, so i scanned the .exe files of all non-working programs with Dependency Walker.

Almost all the missing .dll files are placed now, except 3.

These are:

• API-MS-WIN-CORE-SHUTDOWN-L1-1-1.DLL


• EXT-MS-WIN-MF-PAL-L1-1-0.DLL


• EXT-MS-WIN-NTUSER-UICONTEXT-EXT-L1-1-0.DLL

How can i find this files?
