How To Backup And Recover Files In Windows 10?

How To Backup And Recover Files In Windows 10 Using System Tools?

A lot of people do not take the time to ensure that their files are backed up, and later wish they had done so. There is no excuse for not making a backup. Protecting our data is something we should all be concerned about, especially when we store important photos, documents, or other sensitive files of any format on our computers. Even if you take precautions to protect your computer from malicious software or other potential dangers that could destroy your data permanently, there is still a chance that a hardware failure, accidental error, or other problem might happen. To restore your data without a backup could take time and expense, if indeed it is possible at all.

How To Take A Screenshot In Windows?

How To Take A Screenshot In Windows 7 & 10 Using Keyboard Shortcuts And Other Tools?

A screenshot is a still image saved from the currently visible part of your screen. The process of saving a screen image is called capturing. Here, we show different methods to capture screenshots in Windows 7 and Windows 10.

Possible destinations for the captured image are Windows clipboard (RAM memory), a file on a local hard disk, Cloud-hosted storage or social media, e-mail client for sending a captured screenshot, printer, or editing windows of programs used for taking screenshots. Your screenshot might focus on the entire screen (desktop), a screen of one of your monitors in dual or multiple monitor mode, an active window, or any selected rectangular or even arbitrary shape area. Screenshot capturing can be performed using Windows built-in utilities or third party external programs and web browser-based extensions.

How To Change Your Screen Resolution In Windows 10?

How To Easily Change Your Screen Resolution And Other Display Settings In Windows 10

Resolution refers to the number of pixels on a screen. High resolution means more pixels and more space, whereas low resolution is fewer pixels and often less space. Clarity of images and text displayed on your screen depends on the screen resolution. The higher the resolution, the sharper the items appear. They also appear smaller so more can fit on the screen. Conversely, when your screen resolution is lower, items appear larger but fewer fit on the screen. The larger your monitor, usually the higher resolution it supports. You can increase or reduce your screen resolution depending on the size and capability of your monitor, and this also depends on the type of video card installed.

How To Test Your Random-Access Memory (RAM)?

How To Easily Test Your RAM for errors?

Random Access Memory (RAM) is computer hardware that temporarily stores data within a "working" memory area. The more working memory your system has, the more information it can process simultaneously. You can purchase additional RAM for your computer to improve capacity and performance. Do not confuse RAM with hard drive storage or other memory types. Remember that RAM is temporary storage, whilst hard drive memory retains data until you delete it. Furthermore, RAM is only used when the computer is turned on - as soon as you turn it off, the memory is erased.

How to Know if You Are Running 32-bit or 64-bit Windows?

How to Know if You Are Running 32-bit or 64-bit Windows and What's The Difference?

You may have heard that Windows can be 32-bit or 64-bit. Both operating systems are designed to utilize a processor, which is named accordingly: 32-bit Windows uses a 32-bit processor, whilst 64-bit uses a 64-bit processor. The main difference between 32-bit and 64-bit is that a 32-bit processor can only address 4 gigabytes (GB) of RAM or less. If, for example, your computer has 8GB of RAM (or more) and is running 32-bit Windows, this means that your system will be using no more than 4GB, and the remaining four (or more) GB will be unused. Only 64-bit operating systems can address more than 4GB of RAM. You can run 32-bit Windows on a 64-bit computer, but to install a 64-bit version of Windows, you need a processor that is capable of running a 64-bit version of Windows. A 64-bit operating system can handle large amounts of memory more efficiently than a 32-bit system and can be more productive when running several applications at once and switching between them frequently.

How to Rotate a Video in Windows?

How to rotate a video by 90 degrees?

When you record videos on your camera or smartphone, you might rotate your device between portrait and landscape to achieve better framing. While playing back the videos on your device, you can simply tilt it and see the video correctly, and if you are viewing on a smartphone, it will rotate the screen automatically. When you transfer your video to your computer, however, the orientation will remain as it was recorded - maybe upside down or sideways - and watching it may be frustrating or impossible (literally, a pain in the neck!) Nevertheless, there are several easy ways to rotate your video in Windows with the correct tool. In this article, we will show you how.
