lag.dll - Some say it's a sneaky little file Microsoft stuck in Window

Some say it's a sneaky little file Microsoft stuck in Windows to make your computer feel like it's been hit by a truck.

My computer is slower than my grandma’s walking pace. Lag. dll must be laughing at me.

I opened a photo and my screen froze. It’s probably lag. dll’s fault again.

I swear lag. dll is a secret agent working for Microsoft to ruin my life.
