Episode 1393 (1:27:44)

SanDisk SSD

Sean has a nine year old desktop loaded with software. Will he be able to get updates to Windows XP to end of life? Leo says there's a good chance of that. He just won't get anything through SP2.

He also wants to know if he'll have to defrag his SSD. Leo says no, he won't need to, but he can do it to force TRIM to speed up the SSD.
