Ntdll.dll, Advapi32.dll, Gdi32.dll files explained
The DLL also called Dynamic Linked Library to hold a set of functions available in the Windows 10/8/7 operating system. Another program can call and execute the function. DLLs are built so that they can be updated and managed separately. Today, we explain about three of these DLL files – Ntdll.dll, Advapi32.dll, and Gdi32.dll
Remember that these are Windows system files, that is, part of the main operating system. They are important and should not be deleted. If they are missing, you will need to run the SFC or DISM tools to replace the corrupt files or copy the new files.
1) What is Ntdll.dll

3) What is Gdi32.dll
Gdi32.dll = 32-bit graphics device interface
It contains features required by the Windows or GDI graphics device interface to print graphics and text on a screen and printer. The applications request Gdi32.dll, which in turn sends the instructions to the graphics hardware to complete the drawing and font management requests. It is only available for 32-bit applications. 64-bit applications must use GDI +.
If you manage to delete or the file is corrupted, any application you launch will generate an error stating:The program can not start because GDI32.dll is missing from your computer. Try to reinstall the program to resolve this problem.
If that's what you see, it would be best to start the computer in safe mode and run the SFC tool to replace it with a new copy.
All of these files are located in the System32 or SysWOW64 directory. If you also find them somewhere else, it is best to run your virus scan.
