Can Windows Media Player play M4A without conversion?

Recent Windows builds decode M4A/AAC natively, so no conversion is needed there. The need arises with older setups — WMP 11 on XP-era machines, Windows CE devices, and hardware players from the WMA generation that never learned MP4.

How should I set the bitrate for the WMA output?

Use at least the source's bitrate and prefer 160-192 kbps — WMA's encoder is less efficient than AAC, so matching bitrates exactly drops quality. This transcode compounds two lossy passes, making generous settings the only protection.

Are there M4A files this conversion can't handle?

Apple Music streaming downloads are DRM-protected and won't convert — that protection is tied to the subscription and is intentional. iTunes Store purchases from 2009 onward are DRM-free and convert normally, as do your own recordings.

Carrying M4A audio over to WMA serves the Windows Media generation of hardware — older PCs, Zune-era portable players, and 2000s car units. It exists purely for backward compatibility with Microsoft's pre-MP4 world.

Why convert M4A to WMA?

Play iTunes-era purchases and recordings on Zune-generation players and WMA-first car stereos.
Fit into old office setups where Windows Media Player is the mandated, locked-down audio tool.
Feed dated presentation or e-learning software that embeds WMA more reliably than MP4 audio.

Tip: Both formats are lossy and WMA is the more limited of the two — convert only what the legacy device needs and keep the M4A files as your working copies.
