Some users have reported an issue in which they are suddenly unable to play streaming Windows Media files from various websites. These include the Sirius and XM streaming sites as well as other outlets.
Fix
This issue can usually be resolved by simply setting Windows Media Player as the default playback program. This can be accomplished as follows:
- Click the Start button
- Go to Default Programs>Set Default Programs in Windows Vista (or All Programs>Program Access and Defaults in Windows XP)
- Set Windows Media Player as the default media player.
If the above process does not work, you may need to rename the folder “Windows Media” in %appdata%\local\microsoft then re-try streaming.

Windows Media Player may erroneously deliver the message “Your computer is running low on memory. Quit other programs, and then try again” when attempting to play DVDs, stored movies or other media. This message can be the result of an unregistered Windows Media Player .dll instead of an actual scarcity of memory.
To fix this issue, follow these steps:
- Launch a commpand prompt in administrator mode. Navigate to Programs > Accessories > then right-click “Command Prompt” and select “Run as Administrator”
- Copy and paste the following command: for %a in (%systemroot%\system32\wm*.dll) do regsvr32 /s %a into the command prompt.
- Press enter and wait for the command to process.
After performing these steps, re-attempt usage of Windows Media Player.
