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 off and press ENTER.
   
3. Type exit and then press ENTER to close the Command Prompt window.

To recreate the Hiberfil.sys file and make hibernation available, follow these steps:

1. Open a Command Prompt with Administrator privileges (see instructions above)
   
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.

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.

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.
