  • Bitlocker Encryption for USB Drives Bitlocker Is a Security Feature. the Purpose of Bitlocker Is to Encrypt Your Data
    BitLocker Encryption for USB Drives BitLocker is a security feature. The purpose of BitLocker is to encrypt your data. This is extremely necessary for any data that is not to be shared with other persons. This will prevent anyone from being able to access your files. In order to have access to your files, you will need to provide a secure password. This password should be unique only to you. More information is provided below on how to make a unique password in step 2. During this process, step 3 offers the option to save a recovery key. The recovery key is 48 characters long and consist of numbers and letters. This key will be saved to Active Directory and allow the IS Department to access your USB/External drive should you forget your password. To get started I would recommend encrypting the USB/External drive BEFORE adding any files. Once the drive is encrypted and you enter your password it will function as any other USB/External drive. So you may add, edit, or delete your files as you normally would. If you have any trouble following this guide or have any questions please do not hesitate to contact the IS department. You will need a USB or External drive in order to successfully complete this process. Multiple ways to navigate to BitLocker: 1. Control Panel System & Security BitLocker Drive Encryption 2. Search bar type in “BitLocker” Manage BitLocker Steps to encrypt your USB drive: Step 1: Click “Turn on BitLocker” Step 2: Check the “Use a password to unlock the drive” and enter your password.

  • Getting Started with Windows Speech Recognition
    Getting Started with Windows™ Speech Recognition (WSR) A. OVERVIEW After reading Part One, the first time user will dictate an E-mail or document quickly with high accuracy. The instructions allow you to create, dictate, and send an E-mail without touching the keyboard. The second part discusses steps to attain highest accuracy. The final part has suggestions for increasing productivity when using Windows™ Speech Recognition. II. PART ONE A. WHY USE SPEECH RECOGNITION? Most people will be able to dictate faster and more accurately than they type. My experience with Windows™ Speech Recognition is the ability to dictate over 80 words a minute with accuracy of about 99%. If you truly can type at 80 words a minute with accuracy approaching 99%, you do not need speech recognition. However, even a good keyboarder will benefit from reduced strain on the hands and arms by using Windows™ Speech Recognition. It takes time to become comfortable with dictation into a computer. There will be moments of frustration as you go through the learning curve. If you are impatient or are a perfectionist, DO NOT read on and do not use Windows™ Speech Recognition. If you have reasonable patience, you will learn to dictate accurately and comfortably. The best strategy is to keep things simple for first several days of using Windows™ Speech Recognition. When you are comfortable with the basics, move to part two of this document. B. THE MICROPHONE A good microphone makes dictation into a computer a pleasure instead of a battle. Good microphones reproduce your voice accurately and block out background noise that distorts the audio signal.

  • The Control Panel and Settings in Windows 10 Most Programs and Apps Have Settings Specific to That Program
    GGCS Introduction to Windows 10 Part 3: The Control Panel and Settings in Windows 10 Most programs and apps have settings specific to that program. For example, in a word processor such as Microsoft Word there are settings for margins, fonts, tabs, etc. If you have another word processor, it can have different settings for margins, fonts, etc. These specific settings only affect one program. The settings in the Control Panel and in Settings are more general and affect the whole computer and peripherals such as the mouse, keyboard, monitor and printers. For example, if you switch the right and left buttons on the mouse in the Control Panel or in Settings, they are switched for everything you click on. If you change the resolution of the monitor, it is changed for the desktop, menus, Word, Internet Explorer and Edge, etc. How to display the Control Panel 1. Right-click the Windows Start button or press the Windows key on the keyboard + X. 2. Click “Control Panel” on the popup menu as shown in the first screen capture. In Windows 10, many of the settings that once were in the Control Panel have moved to Settings. However, there are often links in Settings that take you back to the Control Panel and many other settings that still only exist in the Control Panel. Settings versus Control Panel is an evolving part of Windows design that started with Windows 8. It is not clear at this time whether the Control Panel will eventually go away or whether it will simply be used less frequently by most users.
