WMP Tag Plus Version History
Version 2.12 (November 12, 2021)
- Fixed: "One of the core components of WMP Tag Plus is missing or
failed to load properly" error message at Windows Media Player startup
on Windows 11, as well as on newer versions of Windows 10.
Version 2.11 (October 30, 2020)
- New: since Windows Media Player on Windows 10 appears to be designed to never
write any FLAC tag changes to file, WMP Tag Plus now overrides this
behavior and forces Windows Media Player to write the changes to file
after all. A corresponding new setting (which is enabled by default) has
been added to the Advanced tab of the plug-in's settings.
- Fixed: the tag support added by WMP Tag Plus didn't work anymore
since the May 2020 Update of Windows 10 (version 2004).
- Fixed: on high DPI displays, the WMP Tag Plus settings dialog appeared oversized when
being opened from Windows Media Player's Options dialog.
- Windows 10 includes native Ogg Vorbis support but its tagging
capabilities are very limited: only a small subset of tags is supported,
such as duration and bitrate. Because of this, WMP Tag Plus now
overrides the native Ogg Vorbis tagging support in Windows Media Player
with its own tagging support
while the plug-in is active.
- WMP Tag Plus now shows a warning at Windows Media Player startup if
Write media information changes in Windows Media Player's Library
options is turned off, and offers you to turn it back on. This warning
can be disabled by the user. Note that when choosing to turn the setting
back on, WMP Tag Plus needs to restart Windows Media Player for the
change to take effect.
- Fixed: memory leak when using the Refresh song tags
- Fixed: non-responding user interface when using a laptop pointing stick or
touchpad to scroll the credits on the WMP Tag Plus About tab.
Version 2.10 (July 19, 2018)
- Fixed: "Windows Media Player is not installed properly and must be
reinstalled" error at Windows Media Player startup in the Spring Creators
Update of Windows 10.
- Fixed: compatibility issue with Symantec Endpoint Protection
- Fixed: various small memory leaks.
Version 2.9 (January 7, 2017)
- Fixed: in newer versions of Windows 10, the tag
support added by WMP Tag Plus didn't work anymore.
Version 2.8 (October 29, 2016)
- Fixed: Windows Media Player would hang when scrolling the credits on
the WMP Tag Plus About tab if the system had been running for 25
days or more. This bug was introduced in version 2.7.
Version 2.7 (September 11, 2016)
- Fixed: possible "Assertion failed" error when WMP Tag Plus tried to
read the tags of an MPEG-4 file that was tagged by Windows 10's File
Explorer or Windows Media Player. Fix contributed by Dan Hinsley.
- Fixed: in newer Windows 10 builds, the (superfluous) Apple Lossless
support was visible again in settings where it should stay hidden.
- Fixed: memory leak when writing embedded album art to Ogg Vorbis
- Added a fix for Windows Media Player 12 leaking memory while it
reads embedded album art, more information
This fix was actually already present in earlier versions of WMP Tag
Plus, but required a registry change to become enabled. It's now visible
in settings (on the Advanced tab),
and enabled by default for new installations.
- After adding new file extensions in WMP Tag Plus settings while the
plug-in is disabled, the user is now still asked to restart Windows
Media Player when the plug-in gets enabled at a later time in the same
Windows Media Player instance.
- Removed .aac from the default list of supported file extensions
(this only affects new installations).
- Updated the included TagLib library to
Version 2.6 (August 15, 2015)
- Support for Windows Media Player 12 on the final (RTM) release of
- On Windows 10, the plug-in now disables and hides its Apple Lossless
support since it's not needed anymore there (Microsoft has added native
Version 2.5 (March 29, 2015)
- New: support for reading/writing star ratings in FLAC and Ogg Vorbis
- New: support for reading/writing star ratings in MPEG-4 files
(Windows Media Player 11 only). This is compatible with the native
MPEG-4 star rating support in Windows Media Player 12.
- New: when adding new file extensions in WMP Tag Plus settings, the user
is now asked to restart Windows Media Player for the changes to take
effect. After the restart, WMP Tag Plus will scan all library locations
again, so that existing files with the new extensions get added to the
- New: the aforementioned scan of all library locations is also
performed when WMP Tag Plus has just been installed, and has also been
added to the existing Refresh song tags scan.
- Fixed: broken plug-in functionality on Windows 8.1 after
installation of several Windows Updates. Special thanks to rv2798 and
dynaxer for reporting.
- Fixed: with WMP Tag Plus disabled, the usual warning at Windows
Media Player startup didn't appear if the Comodo Firewall software was
- To prevent possible loss of all tags in a music file (as caused by
an overzealous Windows Media Player, especially on Windows 8), WMP Tag
Plus now ignores all tag delete requests for files whose duration isn't
known yet in the library. Such files can be 'fixed' by using Refresh
song tags in settings, after which all tag writes are allowed again.
Version 2.2 (November 29, 2013)
- Fixed: when trying to access the WMP Tag Plus settings while the
plug-in was disabled, either the settings didn't appear or Windows Media
- Fixed: possible broken Apple Lossless support on Windows 8. Special
thanks to Ralph Knox for reporting.
- Fixed: WMP Tag Plus didn't retrieve the duration of MPEG-4 files not
containing any tags.
- Fixed: "Failed to set data for 'PerceivedType'" error on Windows
Media Player startup in some circumstances.
- When installing WMP Tag Plus on Windows 7 or 8 with Windows Media
Player Plus! already installed, MPEG-4 tag support was still disabled by
default to prevent compatibility issues present in older versions of WMP Tag
Plus. Because these issues have already been fixed in WMP Tag Plus 2.0,
MPEG-4 tag support is now always enabled by default.
- Updated the included TagLib library to
This, for one, means that WMP Tag Plus can now also read the audio
properties (duration, bitrate etc.) of Musepack SV8 files.
Version 2.1 (June 2, 2012)
- Fixed: crash when closing Windows Media Player after it had been
opened by double-clicking a video file in Windows 7's Video library.
Special thanks to Lieuandy for reporting and for testing the fix.
Version 2.0 (May 13, 2012)
- New: support for reading/writing embedded album art in FLAC, Vorbis
and MPEG-4 files.
- New: library album art support for all formats. This also fixes the
"Album art can't be changed when a song from the album is in use" error
message when pasting album art in Windows Media Player 12's library.
- New: Monkey's Audio (.ape) and Musepack (.mpc) tag support.
- New: Apple Lossless (ALAC) support for Windows Media Player 12, allowing
Apple Lossless .m4a files to be added to the Music section of the media
library. Before this, Apple Lossless files were always added to Other
media by Windows Media Player 12. Special thanks to John Lockwood for
(Note: Apple Lossless is still supported on older Windows Media Player
- New: Refresh song tags function. WMP Tag Plus can scan the library
for untagged songs of the newly supported formats and re-add these songs
to the library to refresh their tags, freeing the user from having to do this manually. This scan can
be initiated from settings, but will also run once after a clean install
of the plug-in.
- If the WMP Tag Plus plug-in is disabled, it will now show a warning
at Windows Media Player startup, to prevent untagged songs in the
library and tag changes not getting saved to file. This warning can
turned off again easily.
- MPEG-4 tag support now reads/writes the Publisher, Data provider and
Date created tags as well. This is done using the
same format as the native MPEG-4 tag support in Windows 7 and
later. Special thanks to ErikSka for reverse engineering this format and
for providing the necessary code.
- Fixed: when a song was started on Windows Media Player 12 before WMP
Tag Plus had loaded, the tag support for that song's format was not
functional until after a Windows Media Player restart.
- Fixed: on Windows Media Player 12, it was possible that changes in
file extension and tag format settings only took effect after restarting
Windows Media Player.
- Fixed: changes in the plug-in's settings possibly didn't get saved
when the user hadn't switched to the Formats tab.
- Fixed: MPEG-4 tag support wasn't compatible with filenames
containing Unicode characters.
- Fixed: the Beats per minute (BPM) tag didn't get read or written.
- Fixed: WMP Tag Plus always tried to show its settings window on the
first Windows Media Player run after install, even when Windows Media
Player was running invisibly in the background (such as is the case with
Windows Media Center). This also caused 'unauthorized window' errors in
the event log while using a Windows Media Center Extender. Special
thanks to schottjy for reporting and for testing the fix.
- Support for Windows Media Player 12 on Windows 8.
- Updated the included TagLib library to
- Updated the included MP4v2 library to revision 483.
(February 12, 2010)
- Fixed: possible crash while accessing the file properties of a media
file from within Windows Media Player 11.
(November 7, 2009)
WMP Tag Plus failed to correctly write tag changes to certain FLAC files.
Updated the included TagLib to
version 1.6.1, which fixes some other small bugs.
