Users have no need to install any extra software, especially if they are not intending to make changes to the Windows system. Some companies, however, will also need to use a non-Windows application for various reasons. Many of these Windows applications can be used to run at their full potential and functions that were previously reserved for the Microsoft operating system can now be accessed with ease. The hardware in a computer can also be updated using third-party software, such as their motherboard, memory chips, hard drive and so on. It is possible to restore the BIOS or booting from a CD. You can also download new software, as long as it has been developed specifically for Windows, and then run it on your PC.
If you need to update your BIOS on your PC then you will need to use a free program. You can use that particular Windows software to update the BIOS and then use this to boot up. You will be able to use any of the hardware that is present on your computer - the motherboard, graphics card, hard drive, etc. in any order you wish. Sometimes certain hardware components such as hard drives are considered "incompatible" and this causes them to run slower. Having that particular piece of hardware running slower will cause users to be frustrated and to want to give up before they try any further.
In order to speed up your system you can download a Windows upgrade which will also allow you to do some of the same things. This kind of software is very popular and is available in most download sites and even in some online stores. This is how to download free software for your PC that works with all versions of Windows. It is the same software you would use if you wanted to change your PC to use a different operating system.
