If you're a hardcore computer user like me, your system runs 24/7 with no screen or power saver options (I turn off the monitors when not in use). I like to walk into my office and have it ready to go. So when I noticed that my version of Windows still had the Hiberfil.sys file and I do not use hibernation, it was time to remove this file and regain that drive space back (in my case, 16 GB).

The Hiberfil.sys is a hidden system file located in the drive's root folder where Windows is installed. The Windows Kernel Power Manager creates this file when you install Windows. The computer uses the Hiberfil.sys file to store a copy of the system memory on the drive when hibernation is turned on.

The size of the Hiberfil.sys file is approximately equal to how much Random Access Memory (RAM) is installed on the computer. The computer cannot go into hibernation if this file is not present. And even if you have disabled hibernation, your computer can still go to sleep. Here is the difference between sleep and hibernation:

• Sleep: Windows can turn off the screen(s) and drive(s) while continuing to run in memory. A tap on the keyboard or moving the mouse will turn the screen(s) and drive(s) back on.
• Hibernation: Windows takes the active memory, writes it to the Hiberfil.sys, and then turns the computer off. Pressing the power button will start Windows back up, where it loads the Hiberfil.sys file.

How to turn on or off hibernation in Windows

To disable hibernation, you must open a Command Prompt with Administrator privileges. Since this article covers multiple versions of Windows, click on the link below that matches your version of Windows for how to open an Admin Command Prompt. All links open in a new window.

2. At the Command Prompt, type powercfg.exe /hibernate on and press ENTER.
3. Type exit and then press ENTER to close the Command Prompt window.

One of the most useful items I use daily is keyboard shortcuts. Especially shortcuts that I can perform with just my left hand, allowing me to keep my right hand on the mouse. You can use keyboard shortcuts to open frequently used files, folders, and programs like File Explorer. Windows has a ton of built-in keyboard shortcuts (see links at the bottom of this article), plus you can create your own custom keyboard shortcuts. Here are my favorite left-hand keyboard shortcuts.

Press	To
+ E	Open File Explorer
+ R	Open the Run dialog box
+ D	Display the Desktop
+ F	Search for a file or folder (Windows 7 / 8.1)
+ S	Search for a file or folder (Windows 10 / Windows 11)
CTRL + A	Select all
CTRL + X	Cut
CTRL + C	Copy
CTRL+ V	Paste
CTRL + ALT + (KEY)	Custom keyboard shortcut (see below)

Create your own Windows keyboard shortcuts

You can create keyboard shortcuts that use CTRL + ALT + (your choice of a key) for frequently used files, folders, and programs. You will need to have a shortcut to the file, folder, or program you want to open first. You can use an existing shortcut (on your desktop or the Start menu) or create a new one.

How to create a shortcut in Windows

Once you have a shortcut:

1. Right-click on the shortcut
2. From the context menu, click Properties
3. On the Properties box, select the Shortcut tab
   
4. Click inside the Shortcut key box and press the key which you want to combine with CTRL + ALT

Note:
You can not use the following keys for keyboard shortcuts: ESC, ENTER, TAB, SPACEBAR, PRINT SCREEN, SHIFT, or BACKSPACE.

A while back. I wrote an article about creating panoramic images with Microsoft Image Composite Editor (ICE) and Photosynth. With ICE and Photosynth, you can create panoramic images and then upload them to the Photosynth website. But what if you wanted to upload them to your website? That's where HD View comes into the picture.

Microsoft HD View is a new viewer to display large images (gigapixels) across the internet. It allows you to create panoramic images for web pages that do not take a lot of bandwidth. When someone views the image, they are only downloading what is required for that view. It is only when they pan or zoom that more of the image is downloaded. HD View / Deep Zoom is now included in ICE, also as a stand-alone command-line utility, and (here's the best), a Photoshop plug-in.

HD View / Deep Zoom export in Photoshop plug-in

So if you're a Photoshop user, you can now export those panoramic images that Photoshop can create directly to HD View / Deep Zoom format. The Photoshop plug-in is available in both 32-bit and 64-bit. Here's a quote from the HD View website:

About HD View
HD View is a new viewer developed by Microsoft Research's Interactive Visual Media group to aid in the display and interaction with very large images. The HDView development team included Johannes Kopf, Matt Uyttendaele, Howard Good, and Michael Cohen along with Jonathan Fay of the Next Media group.

Recent advances in camera and sensor technology and software for stitching images together has led to the creation of images containing billions of pixels (gigapixels). These images are often panoramic, that is, they cover very wide fields of view. Since monitors typically contain only one to two million pixels, it is only possible to actually see 1/1000th of such image data at once. Also, viewing very wide fields of view require unwrapping of an image projected onto a curved surface (think of a map of the world) which can cause distortions.

HD View leverages current graphics hardware to allow smooth panning and zooming as well as the viewing transformation described below.

HD View was developed with a number of goals in mind. It should:

• allow smooth panning and zooming on large images,
• only download enough data to create the current view (and possibly look ahead to the next), and
• always display the current field of view with an appropriate projection. This means that when zoomed way in you should be presented with a standard perspective projection providing a sense of immersion, and when zoomed out you experience a curved projection so that get a full overview of the scene. In between the projection should smoothly transition.
• Finally, it should be easy to create your own HD View content and present it to the world via the web.

The HD View plug-in currently supports all major browsers on the Windows platform. The first time that you visit a page with HD View content you will be prompted to install the HD View plug-in.

Let's face it, some of the software we use on a daily basis has become subject to security vulnerabilities and exploits. Software manufacturers do their best to develop and test fixes / patches as fast as possible, but this can take time. A lot of users just cannot keep up with all of the updates and hotfixes. A few years ago Microsoft released the Enhanced Mitigation Experience Toolkit (EMET) to deal with just this issue.

So what is EMET? EMET monitors selected programs (Internet Explorer, Microsoft Office, etc.) for known attack actions and techniques. When one of the several pseudo mitigation technologies is triggered, EMET will either block the programs' access to the resource it is trying to reach or just terminate it. EMET expands on the technologies that Microsoft implemented with Data Execution Prevention (DEP), which has been included in the Windows operating system since Windows XP SP2. It will also validate digitally signed SSL certificates inside of Internet Explorer.

So how does EMET work? EMET acts as a shim between the program being monitored and the operating system. The monitored program thinks it's talking directly to the operating system, but it's actually talking to it through EMET. EMET comes with predefined profiles for some of the more common programs like Microsoft Office, Internet Explorer, Adobe Acrobat and Java. You can also add to the predefined profiles or create your own. I recommend that you monitor any program that can open files on or from the Internet.

What security exploits are currently covered

Here's is the current list of mitigations EMET 5.5 currently looks for.

• Attack Surface Reduction (ASR) Mitigation
• Export Address Table Filtering (EAF+) Security Mitigation
• Data Execution Prevention (DEP) Security Mitigation
• Structured Execution Handling Overwrite Protection (SEHOP) Security Mitigation
• NullPage Security Mitigation
• Heapspray Allocation Security Mitigation
• Export Address Table Filtering (EAF) Security Mitigation
• Mandatory Address Space Layout Randomization (ASLR) Security Mitigation
• Load Library Check - Return Oriented Programming (ROP) Security Mitigation
• Memory Protection Check - Return Oriented Programming (ROP) Security Mitigation
• Caller Checks - Return Oriented Programming (ROP) Security Mitigation
• Simulate Execution Flow - Return Oriented Programming (ROP) Security Mitigation
• Stack Pivot - Return Oriented Programming (ROP) Security Mitigation
• Windows 10 untrusted fonts

What programs should you harden / mitigate

You only want to harden / mitigate certain programs that are targeted on a regular basis. Web browsers like Chrome, Firefox and Internet Explorer, production / office programs like Microsoft Word, Excel and PowerPoint, e-mail clients like Outlook and Windows Live Mail are some of the few. I recommend that you harden any program that can open files on or from the Internet.

What programs should you not harden / mitigate

You should never configure EMET to monitor anti-virus, anti-malware, intrusion prevention / detection software, debuggers, software that handles Digital Rights Management (DRM) technologies or software that uses anti-debugging, obfuscation, or hooking technologies.

Installation notes

New installation: Just download EMET and install

Upgrade install: Since the registry keys for EMET changed with this version, you can either export your existing EMET settings using the method in the 'What's new' section below, download the converter or reconfigure all of the program settings. With the drastic change with the EMET data format inside of the registry, I think that it would be just easier to reconfigure EMET then try the export / import method. Either way, remember to uninstall any older version of EMET and restart your computer before you install this version.

What's new in EMET 5.5?

• Full-featured GPO management, compatible with reporting and compliance requirements
• Command line: new syntax and options
• Implementation of certificate pinning now based on root CA thumbprints. Exceptions logic removed.
• Export and Import now memorize path
• EMET registry has been refactored. To convert settings from previous versions of EMET (including EMET 5.5 Beta), registry values must be saved in a file then imported back with the use of the converter PowerShell script after EMET 5.5 is installed. Here are the steps to follow:

1. Export settings. With elevated PowerShell, run the following command:
   .\Migrate-EmetSettings.ps1 -RegFile .\NewEmetSettings.reg -MissingCertCsv .\MissingCerts.csv PowerShell script Migrate-EmetSettings.ps1 is provided with EMET 5.5 RTM. It includes documentation about its usage.
2. Uninstall former version of EMET.
3. Install EMET 5.5 RTM. When asked to choose between Use recommended settings and Configure manually later, chose option Configure manually later.
4. Import settings. With elevated PowerShell, run the following command:
   reg.exe import .\NewEmetSettings.reg

Supported Operating Systems

Windows 10 , Windows 7, Windows 8.1, Windows Server 2008, Windows Server 2012, Windows Server 2012 R2, Windows Vista

• EMET 5.5 requires .NET Framework 4.5.
• For Internet Explorer 10 on Windows 8 you need to install KB2790907 - a mandatory Application Compatibility update that has been released on March 12th, 2013 or any other Application Compatibility updates for Windows 8 after that

One of the questions I often get asked is, "What can I do to maintain my computer". So in this article, I am going to share my five favorite tips for maintaining your Windows-based computer.

Regularly check your drive(s) for errors

This is one of the first things I do when I get a system in the shop. An error on the disk can cause all sorts of issues, so occasionally running a quick standard disk check is recommended. It is always best to try fixing any errors before they become huge problems.

For more information on how to perform a checkdisk, select your operating system below.

Manually defragment and optimize your drive(s)

Even though Windows runs Defrag as part of the routine maintenance (usually weekly), you can always occasionally run it, as it is probably the best single thing you can do to speed up your computer. Imagine a filing cabinet where all of the folders were out of order and files were misplaced throughout the cabinet. How could you find anything? Same thing with your computer's drive. Disk Defragmenter takes care of that for you. And you can run it as a scheduled task too.

Select your operating system below for more information on how to use Disk Defragmenter.

Clean up your drive(s) regularly

Now, Windows does include programs to clean up the miscellaneous files that build up over time, but by default, it is not set up to run automatically. You can set up Windows to perform these routine tasks, which include deleting temporary files and emptying the Recycle Bin.

Install Windows updates when they become available

Once a month, Microsoft releases security patches called Cumulative Updates. They fix known security issues and should be applied as soon as possible. Microsoft has been using the same schedule for
releasing them for decades now. The second Tuesday of every month is known in the IT world as 'Patch Tuesday', so mark your calendar. And if, for some reason, Windows Update does not work correctly, click on the link below.

Troubleshooting problems with Windows Update

Backup of your computer on a regular schedule

Nothing can beat a complete backup when it comes to getting a computer back running after a drive failure. Sure, a drive failure is an extreme example, but it could be an update that did not install correctly or a corrupt driver that is preventing your system from booting correctly. And the software is already built-in; all you need is an external drive for the backup and a USB flash drive for a repair drive.
