Run the game and wait for it to get to the main menu.
Be aware that the MEUITM mod adds a new splash image, so be sure to re-delete/rename it again should you choose to install/reinstall it.
Delete or rename Splash.bmp, this prevents Borderless Gaming from making the splash window borderless, as this causes a crash for unknown reasons.
Compatibility mode for 7 (if you're running 8+) is fine, should you need it. Make sure you haven't set the game to run in compatibility mode for XP nor Vista, the former causes borderless to be glitchy and the latter leads to a crash.
Set the game to run in windowed mode in the in-game video settings, make sure it's set to the same resolution as your desktop.

Obviously you’ll find weapon mods in the veteran and spectre packs, but they won’t be nearly as cost effective if you’re only looking for weapon mods. Weapon mods only come in common and uncommon form, so you really only need to purchase recruit packs to get them. You earn points to buy card packs (or you can use real money if you’d like), open the packs, and you get to use whatever you get from those packs when you play online. In Mass Effect 3 for the PC, PS3, and Xbox 360, unlocking weapon mods to use in multiplayer games is based on a card system.
