Hi there! This is really annoying me now. I recently installed Windows 7 and now when I open a folder containing wav files explorer jumps up to 50 to 80 CPU usage. The folder contains wav music files because I am converting them from 320 mp3, and FLAC to use in Ableton Live, which is a music workstation. The folder it originally happened to came from my previous hard drive, which may have got damaged, so the files might be corrupt.. but this issue didn't happen with the folder in question after the hard drives incident (which may have resulted it having bad sectors), when I was using windows xp. Recently I converted a FLAC file to wav using this new windows 7 install. When I tried to access the folder that it was put it, again explorer jumped up to 80 percent, dllhost.exe is also contributing the cpu strain, with around 30 cpu usage. I googled this and I was recommend to download a patch for windows 7 which promised to solve the exact problem I had, it said something about explorer taking up CPU and corrupt wav files, however even after this fix, I am still having the problem. Any one have any ideas? Its doing my head in. Thanks!
