Step 1: Download Visual Pinball here and PinMAME here.
Step 2: Run the installation for Visual Pinball and install it wherever you please.
Step 3: Unpack PinMAME to the same folder you installed Visual Pinball to.
Step 4: Run setup.exe for PinMAME and configure everything to your liking (Just remember where you're gonna put things afterwards)
Step 5: Download a table and it's corresponding roms from here. Unzip the table into a folder you have assigned for Visual Pinball Tables (Usually the "Tables" folder where you installed VP) and leave the roms zipped in the folder you told PinMAME to use for roms.
Step 6: Download the needed VBS Scripts from here (It's at the top of the page) and unpack ALL of them where you just unpacked your table to.
Step 7: Open Visual Pinball, go to FILE > OPEN and select the table you want. (Don't forget to set your options in PREFERENCES regarding video and keys!)
Step 8: Click on the big PLAY button to the left in the pane, or select TABLE > PLAY from the dropdown menu.
There! You should be playing Pinball games on your PC in no time!
