Customer PC, Windows 10 with Avast IS 11.2, unable to install latest W10 anniversary update (1607)
- error "couldn't update system reserved partition"
Turns out his 100MB EFI System Partition (ESP) only had 13MB available, not enough for an update (15MB?). I looked inside the partition and found that there was a 35MB "snapshots" directory created in May 2016 - after some research it appears that this directory and files are created by Avast, as part of its sandbox virtualization feature. I could not find any reference about this in my searches here or in google, but I did the following and hope that it will prevent Avast from taking up any of the scarce space in the ESP again:
- in Avast Sandbox settings, changed Sandbox Storage setting from "same drive as modified file" to "C:\" - hoping it will henceforth only create snapshots on C:
- deleted existing snapshots directory from ESP
Curious if anyone else has come across this?
cheers,
