I knew something was not right with my PC. No, it wasn’t unstable. It didn’t even crash randomly. However, everything felt delayed. My apps would take longer to open, my browser stuttered at times, and even simple tasks like typing lagged behind my thoughts. When this started happening frequently, I blamed my hardware. I thought maybe it was actually time to upgrade RAM, or even my entire machine. In reality, it turned out that hardware wasn’t the problem. There was one app silently draining performance in the background. And I had no idea until I decided to open a simple Windows tool on my PC.
