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.

How to Disable Startup Programs in Windows 7 & 10?

How to disable startup programs?

Startup programs in Windows 7 and Windows 10 are user programs that are launched automatically after Windows boots on your PC. Any program in Windows can become a startup program if it is included in the Startup programs list. Sometimes, during installation of a Windows program, the user is given the option to include the program in the Startup list. Other programs may be added without such notifications. Often, various programs responsible for product updates and upgrades are added to the Startup list and continually poll update servers for new software versions. Typical examples of startup programs are Spotify, Skype, Dropbox, Microsoft OneDrive, etc. Unfortunately, Malware programs can also appear in your Startup list. It is convenient to maintain useful programs in the list that you know you will need every day, however, the more programs that reside in your Startup, the longer it takes to launch Windows.

How to Open Command Prompt in Windows 10?

Various ways to open Command Prompt in Windows 10 

Command prompt, a command line interpreter application also known as cmd.exe or cmd, is available in most Windows Operating Systems. It is used to execute up to 300 available commands. To use this application, you simply type in the commands or instructions you want and press Enter. It is often used to perform administrative functions, troubleshoot, and solve technical Windows issues. The commands are used to perform certain tasks from the command line rather than the more popular graphical interface (GUI). It is a powerful tool that allows you to do virtually anything that is possible via the GUI, but using text commands. You can move, delete, copy files, create folders, or launch any application. There are some tools that cannot be accessed using the GUI, but are available through Command Prompt. In this article, we show various ways to open the Command Prompt in Windows 10 (these methods also apply to Windows 8 and 7).

How To Electronically Sign Your PDF Documents?

How To Electronically Sign Your PDF Documents in Windows & MacOS?

Are you tired of printing out documents and having to scan them back just to add your signature? There are many ways to sign them electronically. In this guide, we show you how to sign your documents virtually (without the inconvenience of printing, signing, and scanning) before sending. This is a great shortcut, especially when you have a number of documents to sign - save time by electronically signing! Firstly, be aware that there are two completely different signatures: electronic and digital. An electronic signature is a broad category, which includes just a simple image of your signature, whereas a digital signature is far more sophisticated and secure. A digital signature is your identity, which is cryptographically attached to a document and cannot be forged. Do not confuse these two, since this article is about electronic signatures, which are more for personal use. 

How To Prevent Windows from Automatically Downloading and Installing Updates

How To Prevent Windows 10 & 7 From Automatically Downloading and Installing Updates?

In earlier Windows versions (before Windows 10), the automatic update install feature could be disabled - you could still let Windows check for updates, but decide if and when the download and install took place. Alternatively, it was possible to completely disable checks for updates. Installing updates takes time (depending on the size of the updates) and so you may wish to skip or delay this process. Windows 10 automatically downloads and installs updates, regardless. On the other hand, automatic updates are typically a good thing, as they allow improvements to your current system. This is especially important in the security updates area. If, however, you prefer to disable them, this article explains how.

How to Print to PDF?

How to print to PDF in Windows 10 and Windows 7?

PDF is a portable file standard and a more compatible format than other types of documents. Today, most computer or mobile device operating systems can open PDF documents. Usually, you do not require additional software to open and view a PDF file. When it comes to printing to PDF, Windows is not the most friendly operating system to use (if you are using an older operating system, this feature is probably not available). Generally, however, printing to a PDF is quite simple - you can install a free 'PDF printer' or use various other programs. And, if you are using Windows 10, then it is very simple. This article will show you some easy ways to print to PDF in Windows.
