You're doing this at your own risk. If you think you might want to vet each step, you should. 

Worked for me. Your mileage may vary.

1. Download exiftool, an open-source, Perl [sic]-powered tool
• I'll recommend the installer here.
2. Install the exe somewhere and get its location
3. Create a .bat file with this content (hat tip):
• for %%v in (*.%1) do c:\path\to\exiftool.exe -all= "%%v"
• If you want it to recursively spider down folders, use this:
• for /r %%v in (*.%1) do c:\path\to\exiftool.exe -all= "%%v"
4. Call the .bat file in the folder where you have the images
• C:\path\to\myBat.bat jpg
• Note that this does one extension at a time but you can enter * instead to do every file (including non images) in the directory
• C:\path\to\myBat.bat *
• You could also rewrite that bat command to look for common file extensions.
5. Profit.
