Di ko recommended yung third party "pc boosters/turbo" kase unless hindi yan c-r-a-c-k at nagbabayad ka talaga, it will only slow down the system
And for disk defragment, dapat built-in gamitin mo, it's more than sufficient enough to defrag your hard drive. Na trauma na kase ako eh nag bootloop from using third party defrag and I had to manually recover the registry. Pero ikaw bahala haha
