Type of Installations
An Unattended Installation is an automated installation technology that you can use to install with no user intervention. Unattended installation is typically used during large-scale rollouts when it would be too slow and costly to have administrators or technicians interactively install the Operating System/ Software on individual computers.
An example of unattended installation of a software: Paint.net
The installation of an operating system or application on the computer without removing the older version first and without saving any data beyond normal precautions. In-place installations of operating systems have a tendency to cause problems, especially if the new version is very different from the previous one. For example, in-place upgrades are recommended when migrating from Windows Vista to Windows 7, but not from Windows XP. In that case, a “clean install” is recommended, whereby all user data have to be saved externally and restored after the installation, and all applications have to be re-installed.
An example on how to do an In-Place Upgrade: Microsoft
A completely new installation of an operating system or application on a computer. In a clean install of an OS, the hard disk is formatted and completely erased. In a clean install of an application, the older version is uninstalled first. Installing an OS on a new computer or installing an application for the first time is automatically a clean install.
In most cases, a clean install is not necessary when upgrading your operating system. It is much easier and safer to perform a standard “upgrade and install,” which simply upgrades the necessary files and leaves the user files in place. However, sometimes an OS upgrade is not possible because important files have become lost or corrupted. In this case, a clean install may be the only option. Some users may also prefer to perform a clean install so that no lingering problems from the previous OS will affect the newly installed operating system. Additionally, a clean install may be appropriate when installing an OS on a new hard drive or when transferring ownership of a computer to another person.
Windows, Mac OS X and Linux allow you to perform a clean install when upgrading your operating system. The installer will give you the choice between a standard upgrade (typically the default option) and a clean installation near the beginning of the installation process.
How to install Linux
If your installation of Windows 10 is acting up or misbehaving, it is possible to perform a reinstallation of Windows 10 that keeps your files, documents, data, settings, and apps intact. Reinstalling Windows 10 does not format your PC, and can be used to correct problems with missing DLL errors, failed sfc scans, start menu doesn’t work, and more.
Windows 10 repair installs make it possible to fix your PC without resorting to reformat your hardrive. Windows 10 repair install, can also be used to reload Windows 10 system files, registry keys, and configuration to a known working state without the deletion or removal of user files, settings, and software. Reinstalling Windows 10 is not the same as formatting and reinstalling Windows or a clean Windows 10 install – it’s the very last thing you can try if your are experiencing problems running Windows 10 or Windows 10 applications and metro apps before resorting to a system refresh or clean install which would result in the loss of all installed software.
How to repair install your Windows 10
Dual-boot is a term used to describe a computer that utilizes two operating systems. For example, with a dual-boot you could have Windows 10 and Linux on the same machine. The concept of installing more than two operating systems is referred to as a multi-boot.
The interest in dual-booting exists because there isn’t a one-size-fits-all solution to operating systems. While any modern OS will cover the average person’s day-to-day computer needs, for those who need to use specialized programs or want to try more experimental operating systems without sacrificing their computer usability, dual-booting offers a flexible solution.
Windows 10 is the latest and greatest version of Windows, with great performance and a wide selection of programs and games available. However, not all older applications made the jump. Old games without continued developer support are especially likely to function poorly in Windows 10. Every time a new Windows version comes out, its graphics tools and drivers are updated. If the apps don’t get updated by their developers, they may not work.
In this case, you might want to load Windows 7 along with Windows 10 or another OS from the boot menu (more on this below). Apple’s MacOS is popular due to its great usability and features, and Linux is favored by those who want complete control over their operating system. Dual-booting allows you to switch OS on the fly and make the most out of your computer, whatever your preferences and needs may be.

Remote Network Installation
Remote Network Installation is an easy-to-use network application designed for centralized software management and audit across a Network. The program allows you to audit software installed on remote PCs across your network and deploy software automatically on remote PCs. The program deploys software in parallel on remote PCs, so you can deploy within a few minutes across entire network.
