When you buy a new system, reinstall everything
immediately.
I had to use the recovery CD on an eMachine® when Windows ME pooped out after about 1 1/2 years. The process stumbled somewhere around 85% completed, with error messages about a few files that couldn't be read. Then it zoomed onward to 100% and announced that it was finished. When I tried to boot Win Me, there was nothing there.
Then I used a DOS diskette to wipe the HD clean, repartition, & reformat. I tried the restore CD again, twice, with exactly the same results. Good ol` eMachines® gave us a defective CD, and I only found out about it after the warranty was gone.
I installed an illegal copy of Windows 98SE (screw`em, an OS was already paid for once) but the drivers for the motherboard's integrated sound were lost on the defective CD, so I had to add a new sound card. Couldn't use the passive speakers any more either, so I had to get a set of powered speakers too.
