Windows doesn[SQ]t have a single, officially defined list called "STANDARD Codecs." The codecs available and used depend heavily on the version of Windows, installed media players, and any third-party codecs you[SQ]ve added. However, we can talk about codecs *commonly* included or widely supported by Windows :

For Audio:

*

Windows Media Audio (WMA):

Microsoft[SQ]s own format, often included by default.
*

MPEG-1 Audio Layer 3 (MP3):

Extremely common and widely supported, usually handled natively or via a default player.
*

AAC (Advanced Audio Coding):

Often included, especially in later versions of Windows. It[SQ]s the standard for many streaming services.

For Video:

*

MPEG-4 Part 2 (MP4):

A container format that can hold various codecs, very common and widely supported.
*

H.264 (AVC):

A widely used video compression codec typically supported.
*

H.265 (HEVC):

Becoming increasingly common, but support might require updates or additional software depending on your Windows version.

Important Considerations:

*

Container Formats vs. Codecs:

It[SQ]s crucial to distinguish between container formats (like MP4, AVI, MOV) and codecs (like H.264, AAC, WMA). A container is essentially a wrapper; the codec specifies the compression/decompression method for the audio or video *inside* the container.
*

Third-Party Codecs:

Many users install third-party codec packs (like K-Lite Codec Pack) to expand their compatibility with various video and audio formats. These packs aren[SQ]t standard in the sense they[SQ]re not inherently part of Windows itself.
*

Evolution of Support:

Windows support for codecs can change with each version update. Newer formats might require updates or additional software to play correctly.


In short, while some codecs are commonly bundled with or supported by Windows, there[SQ]s no official "STANDARD Codecs" list. The practical list depends on your specific Windows version and any supplemental software you[SQ]ve installed.
