Mammon slept. And the beast reborn spread over the earth
 and its numbers grew legion. And they proclaimed the times
 and sacrificed crops unto the fire, with the cunning
of foxes. And they built a new world in their own
 image as promised  by the sacred words, and spoke
 of the beast with their children. Mammon awoke,
 and lo! it was naught but a follower.

If you’ve already installed windows and want to convert to NTFS file system then you need to use converter tool. Follow the steps shown below to convert your drive to NTFS file system:

1. Open command prompt.
2. Type the following command on prompt:

convert drive_letter: /fs:ntfs

Here you need to replace drive_letter with c: or d: or whatever the letter of the drive that you wish to convert into NTFS. If you converted your partition this way into NTFS then there will be no going backwards. If you wish to back to FAT32/FAT file system then in that case you need to reformat and erase the drive which will remove your data as well. So think before you convert to either filesystem.

1. Right click on empty area on task-bar.
2. Select Properties > Then select “Notification Area” Tab.
3. Turn on “Hide Inactive icons” then click “customize”.
4. You’ll see current active items which you can hide or set to “hide when inactive”.
5. Click OK when you’re done.

Changes will take place immediately once you hit “OK”.
