I'm sure reserving 10GB of space will greatly "improve the reliability" of my Windows installation on a 60GB partition (on a 120GB dual boot SSD) with 5 GB free.
Not sure how I feel about MS hijacking 7-10GB of a system as a “reserved space” to download Windows updates to.
I mean, if that’s what they need to do to get Windows Updates to function with any degree of reliability then their OS is truly fucked.
