Windows 7: Windows Media Player - Rebuild Corrupted Libraries

20 Feb 2015   #40

Microsoft Windows 7 Home Premium 64-bit 7601 Multiprocessor Free Service Pack 1

When I go to C:\Users\(user)\AppData\Local. I get two media player folders. One is just titled Media Player and the other is named Media Player.old.

They both have 37 items, 30 .wmdb files each, 24 in curly brackets (archived?) and 6 that aren't. What to do? I'm not sure I want to delete either folder. I wonder if this is why I have to rebuild the library so often. I sometimes do it from within WMP, sometimes when the troubleshooter pops up and sometimes from the Fixit file Microsoft provides online. I've used your method also, Gornot, until now... I don't know what to delete.

Had this same problem with a trashed library db.

For me this happened when I tried to upgrade in place from Windows 7 to Windows 10. Turned out that there was some graphics driver incompatibility between the W10 drivers for my Mobo Intel chipset and my NVidia GE200 card. So after about 3 days of trying everything the Internet and Nvidia had to offer, I had to get some real work done (as opposed to working unpaid hours debugging their products for them!). I had no choice but to drop back to Windows 7.

After that point my WM library was hosed (I'm surmising because Windows 10 does some changes to it that don't get undone during the drop back and therefore the W7 service manager thinks it's trashed?). Whatever the cause, each time I restarted WMP after that it embarked on a complete library rebuild and volume levelling exercise - which takes a good long while

Followed this procedure and now (after a single rebuild cycle lasting over 6 hours - mostly re-volume-levelling - it is a BIG library) all is well again. the library persists at the next start-up of the system without a rebuild.

Thanks guys.

So I was just starting to love libraries in Windows 7 and decided I'd setup WMP on my media server, and now I'm stuck.
