Take advantage of Windows 8 apps

Windows 8 comes included with several apps to help you get the most from your computer. Below are just a few of the included apps.

People

Microsoft touts the People feature in Windows 8 because they understand how many people are using social networks today. In the People feature you'll be able to connect your Windows computer to all the major social networks including Facebook, LinkedIn, and Twitter. Once connected, you can pin the people app and monitor your social network (as shown below), use People in Search to find people, and get an overview of what is happening in all your social networks.

Reader

The Reader app will give you PDF support right out of the box.

SkyDrive

The SkyDrive app will give you access to the Microsoft cloud service SkyDrive, which allows you to store your photos, documents, and other files in the cloud and access or share those files with any computer with Internet access.

Store

Take advantage of the Windows Store and install one or more of the thousands of available apps designed for Windows 8. The Store is found in the Start screen, or use Search to search the Store app for any apps that you are trying to find.

Windows 8 Task Manager

The Windows 8 Task Manager has been significantly improved over previous versions of Windows. Some of the new changes include showing a total percent usage at the top of your Processes, which makes it easier to determine total memory and CPU usage, improved Performance graphs, a Startup tab to see startup processes and their impact to system performance, and the App history tab (as shown below) that gives you the total resources an app has used over a period of time. Press Ctrl + Shift + Esc to start exploring the new Task Manager.

Employ the hottest hotkeys of Window 8

In these key combinations, hold down the Windows key (normally located between Alt and Ctrl) and another key, as described on this list.

• Press the Windows key to enter the tiled Start screen.
• The Windows key + M minimizes everything that's showing on the desktop.
• The Windows key + E opens Explorer for quick access to folders.
• On the Start screen, press the Windows key + D to instantly get to the desktop.
• The Windows key + Tab opens a list of currently running programs.
• The Windows key + Print Screen takes a screenshot and saves it in a Screenshots folder nested in your Pictures folder. 
• To take a screenshot on a Windows 8 tablet, simultaneously press the Windows button and the volume-down button on the tablet chassis.
• The Windows key + Q opens a global search menu. Type what you're looking for and where you would like to look.
• The Windows key + W opens a search in your system settings to quickly locate and change system properties.
• The Windows key + F opens a file and folder search.
• The Windows key + Pause opens the system properties page to show you a quick rundown of your specs.
• The Windows key + "," (that's the comma sign!) makes all current windows transparent, giving you a peek at the desktop as long as you hold down the Windows key.
• The Windows key + "." (the period) snaps a window to the right or left side (toggling each time you press ".").
• The Windows key + R prompts the Run command—useful for quickly launching apps and other routines with a command prompt.
• The Windows key + X opens the Quick Access Menu, exposing system functionality such as the Command Prompt, Disk Management, File Explorer, Run, and more. Alternatively, you can right-click on the bottom right corner of the screen to spawn the Quick Access Menu.
• The Windows key + I opens the settings menu, giving you quick access to the Control Panel, Personalization, and your Power button, among other features.
• The Windows key + O locks orientation on devices with an accelerometer.

Use a picture password to log into your computer

Windows 8 includes a new feature called Picture password, which allows you to authenticate with the computer using a series of gestures that include circles, straight lines, and taps. Enable this feature if you want a new way to access your computer or have a hard time with passwords.

1. Open the Windows Charms.
2. Click Settings and then More PC settings
3. In the PC settings window click Users and then select Create a picture password

Bonus tip: A four digit pin password can also be created and used to access your computer.

New 25 GPU Monster Devours Passwords In Seconds

ditor’s note: I’ve updated the article with some new (and in some cases) clarifying detail from Jeremi. I’ve left changes in where they were made. The biggest changes: 1) an updated link to slides 2) clarifying that VCL refers to Virtual OpenCL and 3)  that the quote regarding 14char passwords falling in 6 minutes was for LM encrypted – not NTLM encrypted passwords. Long (8 char) NTLM passwords would take much longer…around 5.5 hours.  

There needs to be some kind of Moore’s law analog to capture the tremendous advances in the speed of password cracking operations. Just within the last five years, there’s been an explosion in innovation in this ancient art, as researchers have realized that they can harness specialized silicon and cloud based computing pools to quickly and efficiently break passwords.

A presentation at the Passwords^12 Conference in Oslo, Norway (slidesavailable here - PDF), has moved the goalposts, again. Speaking on Monday, researcher Jeremi Gosney(a.k.a epixoip) demonstrated a rig that leveraged the Open Computing Language (OpenCL) framework and a technology known as Virtual OpenCL 
Open Cluster (VCL) to run the HashCat password cracking  program across a cluster of five, 4U servers equipped with 25 AMD Radeon GPUs and communicating at  10 Gbps 
and 20 Gbps over  Infiniband switched fabric.

Gosney’s system elevates password cracking to the next level, and effectively renders even the strongest passwords protected with weaker encryption algorithms, like Microsoft’s LM and NTLM, obsolete.

In a test, the researcher’s system was able to churn through 348 billion NTLM password hashes per second. That renders even the most secure password vulnerable to compute-intensive brute force and wordlist (or dictionary) attacks. A 14 character Windows XP password hashed using LM NTLM (NT Lan Manager), for example, would fall in just six minutes, said Per Thorsheim, organizer of the Passwords^12 Conference.

[Note of clarification from Jeremi: "LM Is what is used on Win XP, and  LM converts all lowercase chars to uppercase, is at most 14 chars long, and splits the password into two 7 char strings before hashing -- so we only have to crack 69^7 combinations at most for LM. At 20 G/s we can get through that in about 6 minutes. With 348 billion NTLM per second, this means we could rip through any 8 character password (95^8 combinations) in 5.5 hours." ]

“Passwords on Windows XP? Not good enough anymore,” Thorsheim said.

Tools like Gosney’s GPU cluster aren’t suited for an “online” attack scenario against a live system. Rather, they’re used in “offline” attacks against collections of leaked or stolen passwords that were stored in encrypted form, Thorsheim said. In that situation, attackers aren’t limited to a set number of password attempts – hardwareand software limitations are all that matter.

The clustered GPUs clocked impressive speeds against more sturdy hashing algorithms as well, including MD5 (180 billion attempts per second, 63 billion/second for SHA1 and 20 billion/second for passwords hashed using the LM algorithm. So called “slow hash” algorithms fared better. The bcrypt (05) and sha512crypt permitted 71,000 and 364,000 per second, respectively.
