Performance :: Computer Powers On Itself Every Day At 6 Am

A note about that complex command on PowerShell, it returned this:

PS D:> Get-ScheduledTask | ? { $_.Settings.WakeToRun -eq $true -and $_.State -ne "Disabled"} | % { $_.Settings.WakeToRun = $false; Set-ScheduledTask $_ }

I can't take this anymore. I find it useful to put the PC on sleep or hibernation because I have a lot applications open for work and I find it useful not having to close all down every day and reopen the next day. But lately, either I put the PC on sleep, hibernation or even I shut it down, it wakes up 95% of the times at 6 a.m.
