Free disk space & space used by a single Flash Update.

Am I the only one to notice and complain over this in W8.1.

This morning a new Adobe Flash update has appeared, KB3079777. The update is sized at 17.9mb. Nothing is running on the PC, its idle and with no disk activity. Free space is 55.4GB. I apply the update and free space immediately falls to 54.9gb. This behaviour is consistent with every such patch applied. Now over time, that space will return which suggests that something else is going on here. But what ?

Looks like it is just me then. Today brought a 4.6Mb W8.1>W10 computability update. My free space changed from 55.2Gb to 54.7Gb.

Sounds about right. Ho hum....

For now I still have a 1TB HDD, I wouldn't notice anything unless its a few GB.

Mooley how large of a hard drive do you have? Newegg.com still has 1TB 3.5" Platter drives on sale for around $56.

I have the OS on a deliberately 'small' 80Gb partition (320Gb disk) . It suits my needs and ensures any backups are quick and manageable. The size of the HDD doesn't matter for this though, its the fact that so many updates seem to need this massive payload. Or, is it some quirk and in reality its more a problem of the way space is reported although any corresponding backup suggests otherwise, it does seem very real.

For a 4.6mb update to trigger useage of 0.5Gb suggests a lot is going.
