This morning a blue banner appeared on my screen asking me when I wanted to restart my computer to continue to download the update to Win 8.1 (I have Windows 8). At no time did I start the download process. I selected "Remind me later" from the drop
down. A few minutes later, the download started, and the drop down only allowed me to select a time period to restart my computer (Now, 1 hour, 2 hours, 4 hours)!. I was committed, and I never authorized this! So I selected "Now" just to see what would
happen. I went to the Windows Store and lo and behold the update was downloading. The update failed (I got an error 0xC1900101). I disabled the update notification reminder using regedit (I was sick of seeing it every time I powered down my computer anyway)-but
how could this happen? This looked like a legitimate Windows notification.
