My new job provided me a laptop 6 months ago. It was NOT out of the box but was ordered refurbished. They told me I could blow away the operating system so I installed Linux and Windows side by side with most of my activity on the latter. I'm planning on switching concentrations within my field and want to take online classes. Unfortunately my personal laptop went down yesterday and can't afford another one right now. Since I deleted the original OS and installed from scratch can my employer still see that I'm taking classes online, away from company premises at my house?
