Windows 7 Tips & Tricks Guide

The cool tips and tricks that make Windows 7 fun.
here are the best ones to help you get the most out of your Win 7.


1. Use Keyboard Shortcuts

Using the mouse, you can drag-‘n-dock windows to either side of the screen, or drag it to the top to maximize it. These keyboard shortcuts are even faster:

• Win+Left Arrow and Win+Right Arrow dock the window to the left and right side of the screen
• Win+Up Arrow and Win+Down Arrow maximize and restore/minimize
• Win+M minimizes everything
• Alt+Up, Alt+Left Arrow, Alt+Right Arrow navigate to parent folder, or browse Back and Forward through folders in Explorer
• Win+Home minimizes/restores all open windows except the active window
• Alt+Win+# accesses the Jump List of program number ‘#’ on the taskbar.

2. Access Jump Lists with the Left Mouse Button

Jump Lists usually show up when you right-click on a taskbar icon. However, they can also be accessed by holding the left mouse button and dragging upwards. If you’re using a laptop touchpad or a touch screen, this is convenient because you do not have to click any button to access a context menu.

3. Add Any Folder to Favorites

You can add any library or folder to the Favorites section in Windows Explorer. To add a folder, navigate to it in Explorer, right-clickFavorites in the left navigation pane, and select Add current location to Favorites. Now you get quick access to your favorite folders in all File->Save As dialogs!

4. Pin Frequently Used Folders to the Taskbar

Right-click, drag, and pin your favorite folders to Windows Explorer on the taskbar. They will now show up in the Jump List when you right click on Explorer giving you quick access to your favorite folders.

5. Pin Control Panel to the Taskbar

You cannot pin the Control Panel to the taskbar via the Start Menu or by drag and drop. Open the Control Panel and right-click its taskbar icon to pin it to the taskbar. An advantage of this is that Control Panel’s Jump List allows quick access to recently used functions.

6. Create Keyboard Shortcuts for Programs

You can create keyboard shortcuts for any program in Windows 7. Right-click the program icon and select Properties. Select theShortcut tab, click in Shortcut key, to set the keyboard shortcut for that program.

7. Open Command Prompt in Any Folder

Like the command prompt? Miss the ‘Open Command Window Here’ Windows XP power toy? Press ‘Shift’ when right-clicking on a folder to get that option in the context menu. This also works on the desktop. No power toy required!

8. View Expanded ‘Send To’ Menu

Press Shift when right-clicking on a folder to get an expanded Send To menu.

9. Adjust Screen Text with Clear Type

Use Clear Type Tuner for the best look on your LCD monitor or laptop screen. Run ‘cttune.exe’ from the Start Menu search box, or go to the Control Panel Display applet, and select Adjust ClearType Text from the left.

10. Get Exact Colors On Your Screen

If you are an artist or you work with colors, use the Calibrate Color option in the Control Panel Display applet or run dccw.exe from the Start Menu search box. You can adjust gamma, brightness, contrast, and color balance, ensuring that colors are displayed correctly on your screen.

11. Customize the Power Button

If you restart your computer more often than you shut it down, change the default Shutdown power button to Restart. Right-click on Start, select Properties, and choose the Power button action that you use the most.

12. Customize Number of Items in Jump Lists & Start Menu

Right-click Start, select Properties, click Customize and choose the number of recent programs to be shown in the Start Menu and the number of items displayed in Jump Lists from the Start Menu Size section below.

13. Search Internet from the Start Menu

Enable Internet search from the Start Menu using your default browser. Run GPEDIT.MSC from the Start Menu search box to start the Group Policy Editor. In the left pane, go to User Configuration->Administrative Templates->Start Menu and Taskbar. In the right pane, right-click to Edit and Enable Add Search Internet link to Start Menu. 

14. Add Videos to Start Menu

Windows 7 does not place a link to your videos on the Start Menu by default. To add a link to your videos on the Start Menu, right-clickStart, select Properties, click on Customize. In the Videos section at the bottom, choose Display as a link.

15. Single Click Screen Lock

You can lock your computer using the Win+L keyboard shortcut. Here’s another way to do it with a single mouse click. Right-click on your desktop, select New, Shortcut. In Type the location of the item, enter rundll32.exe user32.dll,LockWorkStation. Click Next, name the shortcut ‘Quick Lock’, and Finish.

If you wish, you can make it look pretty by giving it a lock or keys icon: Right-click, select Properties, click Change Icon, entershell32.dll, and select any icon you wish. Drag this shortcut and pin it to the taskbar, after which you can delete the desktop shortcut.

16. Customize Sticky Notes

You can format your Sticky Notes, by selecting text and using different keyboard shortcuts as shown in this screen capture:

17. Shortcut to Run Program as Administrator

You can Ctrl+Shift+Click on a taskbar icon to run the application as an Administrator with full rights (provided your account has permissions). Simply Shift+Right-Click on any program shortcut to run it as a different user, if for example you need higher privileges when logged in with your child’s account.

18. Boost performance with ReadyBoost

ReadyBoost improves your system performance by using faster USB Flash Drives instead of slower hard disks for system operations. It works best using flash drives with at least 1 GB of storage. Simply insert your flash drive, and if it meets certain performance benchmarks, Windows 7 will ask you if you want to use it for ReadyBoost and recommend the size to reserve.

19. Secure USB Drives with BitLocker

Secure your USB flash drives using BitLocker encryption. Right-click on your USB drive in My Computer, select Turn on BitLocker and follow the instructions to protect sensitive data on your thumb drives.
The next time you use your USB drive on another computer, it will prompt you for the password before allowing you read-only access to your flash drive. You can even use the drive on older computers running Windows XP/Vista.

Follow the next tip only if you’re knowledgeable enough to edit the Windows registry. Before making any changes, make sure you back up your registry.

20. Faster Thumbnail Previews

The taskbar shows thumbnail previews of opened windows when you hover the mouse over the program icon. By default, it takes a little time for the preview to appear. Make the previews appear faster with this registry tweak:
Go to Start, enter and run regedit. Navigate to HKEY_CURRENT_USER\Control Panel\Mouse. On the right, open theMouseHoverTime key and reduce its value from the default 400 to around 150.
Be careful, as decreasing it further may cause problems.

10 Reasons why PCs Crash - Must Know

• "Fatal error: the system has become unstable or is busy”

• Blue Screen of Death.
• Fatal Exception Error. (RAM)
• Parity error messages. (RAM)
• RAM lock up and freeze the computer’s display. (BIOS)
• Fatal OE exceptions and VXD errors. (Video Card)
• Computer can not start.
• Computer loop on BIOS.
• Blank screen
• Black screen of Death.

Cause of problem:

1. Hardware conflict

The number one reason why Windows crashes is hardware conflict. If there are a lot of devices, or if the hardware are not installed properly, when the user tries to use both devices at the same time, a crash can happen. 

Sometimes mismatch driver also can make your device can function properly.

Troubleshoot:

• Go to 'Device Manager' to check if all your device functional properly and all the driver for the device is install.
• Make sure your computer drive is up-to-date.

2. Bad Random-Access Memory(RAM)

RAM problems might bring on a fatal error message that indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing. But a fatal error caused by RAM might be caused by a mismatch of chips or mismatch speed of RAM. 

Troubleshoot:

• Enter the BIOS settings and increase the wait state of the RAM.
• Rearrange the RAM chips on the motherboard, or take some of them out.(Do not to touch the gold connections, as they can be easily damaged.)

3. BIOS settings

A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up. Usually BIOS problem is come up, if you change something in the BIOS and the computer becomes more unstable.

Troubleshoot:

• Write down on a piece of paper all the BIOS settings that appear on the screen. That way, you will know what settings to revert to.
• Restore BIOS setting to default.

4. Hard disk drives

After a few weeks, the information on a hard disk drive starts to become fragmented. Hard disks will slow down and crash if they are too full.

Troubleshoot:

• Defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. (Use Windows Disk Defragment or any defragment application such as Diskeeper.)
• Empty the Recycle Bin every week to free more space. 
• Scanned your hard disk every week for errors or bad sectors.

5. Video card

Troubleshoot:

• Take a look at the color settings in 'Display Setting'. For most desktops, high colour 16-bit depth is adequate.
• Make sure it does not have a hardware conflict. Check it in 'Device Manager'
• Look up your video card’s manufacturer on the internet and search for the most recent drivers for it.

6. Viruses

Some viruses erase the boot sector of a hard drive, making it impossible to start. Viruses also can 'eat' all your files in your hard drives including system files. 

Troubleshoot:

• Install and update antivirus in your computer.
• Install also spyware application such as Spyware Doctor.

7. Printers
The action of sending a document to print creates a bigger file, often called a postscript file.

Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer’s performance.

Troubleshoot:
A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer’s default settings and you may be able to carry on.

8. Software

A common cause of computer crash is faulty or badly-installed software. Incompatible software also cause of this problem. For example, you install Bitdefender and Kaspersky antivirus in a computer. 

Troubleshoot:

• Use application like Your Uninstaller to uninstall this software.
• Make sure you have remove all the software before install a new software. To be safe, restart your computer after uninstall or remove a software.
• Use registry cleaner like Registry Booster to remove obsolete entries.
• Entering Safe Mode(Press F4 when Windows Start). Restore your computer to previous restore point.

9. Overheating

Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or fills with dust it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.

Troubleshoot:

• Install bigger and faster fan on the CPU.
• Install more fan to make air flow move faster.
• Clean your fan.

10. Power supply problems

Sometime computer crash because data lost in your computer. Computer is not properly shutdown may be the cause of the problem.

Troubleshoot:

• Buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.

GOD MODE in Windows 7.

GodMode is actually a hidden (or, at least it used to be hidden) developer shortcut in Windows 7 that provides more direct access to features and functions of the operating system. To be clear, GodMode doesn't add functionality. But it helps administrators work more efficiently by collecting all these tweaks and controls in one place.

Accessing GodMode in Windows 7

Follow these steps to access GodMode:

• Create a new folder wherever you want the GodMode folder to be. Right-click in Windows Explorer, select New, then click Folder.
• Next, rename the folder. You can name the folder anything you like as long as you add a period followed by this exact text string: 
  GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}
• The folder icon should be replaced by the Control Panel icon, and the folder should now be filled with a variety of tweaks and tools.
