Serious iPhone sync issue

Just got a new iPhone SE and have been making tracks in Garage Band for about a week.  Plugged into the PC and iTunes ask something about do I want to authorize the purchases on this device or something like that.  I cancel out, change nothing on the phone, then unplug. 

After this I notice several icons are missing, including Garage Band.  After re-installing it all 30+ of my Garage Band tracks are gone.

Windows 10 - Toshiba Satellite e55 running hot

In Win8 I watched my temps closely and was usually around 38 to 44 c under a normal load.  However since upgrading to Win10 I noticed my normal idle temps were around +45c.  Even if the computer was untouched for several minutes and the task manager said CPU usage was below 5% the CPU temps would remain high and the CPU frequency would remain high.

After installing some Toshiba drivers and switching the battery / power mode to the Toshiba's "eco" mode the temps and CPU frequency dropped immediately.  As I make this post my CPU ghz is at .78 and my temp is 40c.  Before changing to Eco the CPU mhz were constantly around 1.3+ ghz even at idle.  So even when the CPU was doing nothing Windows 10 was not scaling down the CPU freq the way it should.

Centos 7 trouble with Grub and dual booting Windows 7

Just installed Centos 7 and realized Windows is not in the boot menu. Searching turns up a lot of advice saying to edit this file
and to add some code, and then run this
grub2-mkconfig --output=/boot/grub2/grub.cfg
In my case this does not help. The Windows installation is still not detected even though I can see it on fdisk -l and have triple checked all of the commands and partition numbers. But the utility Grub Customizer is able to see the Windows partition!

 When trying to make the list I got an error about no such file, to fix this I clicked

File > Change Environment

and then changed the references to fedora to centos (confirmed via console).

 In summary :

 - for some reason sometimes grub2-mkconfig can't see Windows

 - but if you install Grub Customizer it can

 - if it gives you an error make sure the paths are right in File > Change Environment

NOTE : if you get the error and have to fix the file paths be sure to click check box Save Configuration, restart Grub Customizer, then try again

Ubuntu / Mint : "error: symbol 'grub_efi_find_last_device_path' not found"

A few months back my working Ubuntu / Windows setup suddenly stopped working.  Ubuntu boots fine but trying to open Windows gave an error like this :
"error: symbol 'grub_efi_find_last_device_path' not found"
The cause here is a bug in grub2.  To fix force a downgrade to the previous version of grub2.

World of Warcraft won't open - rundll32 high cpu usage

Very recently WoW stopped opening for me. I click the icon, my CPU usage goes to 100% but the game never loads. When I check task manager it says rundll32 is what's causing the high cpu usage. Recently I installed "360 Total Security" with has a Game Booster mode. I tried to exit the AV but still had the same problem. After I uninstalled 360 Total Security and rebooted World of Warcraft opens fine again.
