Caution
Windows
Installing a program might overwrite shared system files such as dynamic-link libraries (DLL files)* and
executable files (EXE files). When system files are overwritten, system performance becomes unpredictable,
programs behave erratically, and the operating system can fail.
Never delete files with the following extensions: SYS, DLL, OCX, TTF, or FON.
In Windows
DLL, OCX, TTF, FON, and EXE files. Windows File Protection runs in the background and protects all files
installed by the Windows Setup program.
Windows File Protection detects attempts by other programs to replace or move a protected system file.
It also checks the file's digital signature.
* This is an operating system feature that allows executable routines (generally serving a specific function or set of functions) to be
stored separately as files with DLL extensions. These routines are loaded only when needed by the program that calls them.
File Signature verification

files with unsigned or incompatible versions, which provokes system instability.
