February 6, 2016.- Bluetooth technology allows wireless communication between devices such as gaming consoles, printers, keyboards, mice, USB dongles, mobile phone headsets, etc. It can connect several devices, interference-free.
Bluetooth has a relatively short working range, which makes it less susceptible to electronic interference than is the case with 802.11 wireless systems.
Bluetooth security has been improved a great deal since Bluetooth first became available, but it is still a cause of concern.
Bluetooth Connectivity Threatens Your Security  -
How Bluetooth Works - Security -
Bluetooth wireless protocols have improved since first becoming available. It is now an ideal way of connecting small devices. By 2014, the Bluetooth protocol was up to version 4.2.
Bluetooth Devices -
Now, it is faster, provides improved security, increased range (up to 300 feet) and is even powerful enough to handle streaming music and HD video. Version 4.0 was released in 2010. It provides support for both high-performance and low-power applications. Bluetooth can be added to a PC via simple USB adapters.
Windows 8.1 and Windows 10 provide built-in support for Bluetooth. It can be added to earlier versions of Windows, which don't provide native support for it, by making use of a cheap USB/Bluetooth adapter. Here is an article on how to add a Bluetooth device to Windows Vista and Windows 7, which differ from each other:

Windows 10 Makes Bluetooth Smart Magic -
For less than U.S. $20, tiny, state-of-the-art Bluetooth 4.0 adapters, made by manufacturers such as IOGEAR and Medialink, are available that are backward-compatible with previous versions of Bluetooth. Moreover, the adapters can be upgraded to the latest version of Bluetooth by upgrading their firmware if it is made available for a particular device from the device-manufacturer's website.
February 1, 2016. - Distributions of Linux, most of them free to download and use, have come on in leaps and bounds in recent years in their user-friendliness. They can be used on the most up-to-date PC hardware and work very well indeed on old computers that are labouring under a version of Windows, such as Windows XP and Windows Vista.
How many people know that Google’s mobile operating system, Android, is a development of Linux, as is Google’s Chrome operating system used on web-based Chromebooks?
Most people have used a tablet or smartphone that uses Android and know how easy it is to use. Fully-featured versions on Linux, such as Ubuntu, come with all the free software, such as the LibreOffice suite, that most users need and work from a modern desktop similar to a version of Windows and Apple’s OS X.
Ubuntu and many other distributions of Linux can work from its boot disc, created from an ISO-file download, or a flash drive without being installed (very useful to use it as a troubleshooting tool if you can’t get Windows to boot) or it can be installed on its own partition to run alongside Windows.
There are some small distributions that function wonderfully well from a USB flash drive, providing an office suite, various tools and apps. Some of them are self-contained and don’t use a PC’s hard drive or SSD storage space and others use the PC’s storage space temporarily without installing anything. If the Linux distribution is self contained on a flash drive it is fully portable, that is, can be used on any computer with a USB port.
Such Linux distributions use generic device drivers wherever possible instead of brand-name drivers, thereby getting around the problems that would be created by incompatible drivers.
Here are some Linux distributions or information sites that you can try or explore:
1. – Ubuntu for desktops – provides all of the software that a home, school or other organisation would require, including built-in firewall and malware protection. It can boot and be run from its installation disc. –
2. – PuppyLinux – a complete operating system with a file size of only 300MB – very easy to install on a flash drive and use. Works very on computers designed to run Windows XP. –
3. – “Pendrivelinux provides simplified information to make it easy for anyone to install, boot, and run their favorite Linux Distro from a portable flash drive!” – http://www.pendrivelinux.com/
4. – Distrowatch keeps track of all of the available distributions of Linux. Use its customisable Seach box to find what you want. –
5. – Neverware Cloudready is a customised distribution of Google’s Chrome operating system used on Chromebooks, which are specifically designed to be used online. Most old laptops will run it. Chrome is a distribution of Linux, so it is open-source and can be developed by any other developers, as in this case.
Online storage is used extensively and the software it uses the provide wordprocessing, spreadsheet and presentation are Google’s online apps. It has a free and a paid-for version that provides more features. Cloudready can work on most computers dating back to 2007. Tutorials are available online on how to install and use it. –
January 21, 2016. - The vast majority of desktop and laptop PCs run on processors made by Intel and AMD.
Windows 7 SP1 and Windows 8.1 have extended security support from Microsoft to January 14, 2020 and October 1, 2023, respectively, but, according to Microsoft, only if they are not running on the upcoming Intel's Kaby Lake and AMD's Bristol Ridge processors (CPUs). Moreover, PCs using Intel's current processors, code-named Skylake, have been given 18 months notice to upgrade to Windows 10 Home, Pro or Enterprise editions. The previous generation of Intel processors, code-named Broadwell, and earlier generations of Intel processors will continue to be able to run Windows 7 SP1 and Windows 8.1.
For your information, the Windows Device Manager identifies the processor a PC is using under its Processors heading. If that information is not sufficient to identify it, there are several free tools that identify PC hardware, such as the Belarc Advisor. After the CPU has been identified, use the name as a web-search query to find out what its code-name is.
Most home users buy a desktop or laptop PC and then continue using the version of Windows that it came with, which will be Windows 10 on new PCs, so this apparent state of affairs, which goes against the support policies that Microsoft has been using for decades, won't affect most people, but it will definitely affect businesses, most of which take their time to upgrade to a new version of Windows, because staff are trained to use the version being employed and it works well.
Microsoft is very keen on getting as many Home, Pro and Enterprise users to migrate to Windows 10. To the extent that Windows 10 is free until July 2017 and some Windows 7 and 8.1 users that have hardware that Windows 10 supports have been upgraded to Windows 10, by Windows Update online, automatically, that is, without their consent. I have a laptop that is 8 years old that I upgraded successfully to Win10, so Microsoft has gone out of its way to make Win10 work on as many elderly PCs as possible.
As usual, there is more to this announcement from Microsoft than meets the eye. It is very difficult to avoid being misled by governments and big business these days. Spin and deception is the name of their game. People in the know say that upcoming processors won't require windows 10, that is not wholly true, Windows 10 is required to use all of features of the new upcoming processors from Intel and AMD. In short, you will be able to downgrade a new desktop or laptop PC from Windows 10 to Windows 7 and 8.1, but the new CPU features won't work.
It is the computer-motherboard manufacturers that provide the UEFI BIOS and the device drivers that support different versions of Windows. For example, you won't be able to buy a new motherboard that supports Windows XP because the motherboard manufacturers no longer provide the device drivers that run the motherboard's chipsets. Therefore, it is unusual for Microsoft to announce that only Windows 10 will be able to run on upcoming processors and that Intel Skylake processors will only be able to do so until July 2017. We will have to wait to find out what those manufacturers and Intel and AMD have to say about this.
Remember that you can only transfer a retail-licensed copy of Win7 and Win 8.1 on to a new PC, not an OEM-licensed version that brand-name PC manufacturers supply, because an OEM version can only ever be installed on one computer. Even if the motherboard is changed to a different make or model on that one PC, it requires a new licence. A retail copy of Windows can be installed on as many PCs as the user likes as long as it is only being used online on a single computer at any one time. If it is installed on more than one, it falls foul of Microsoft's Product Activation.
Skylake users given 18 months to upgrade to Windows 10 -
The following forum thread discusses the implications of this new state of affairs.

January 16, 2016. - Windows' Encrypting File System (EFS) is not active by default, the user has to choose to enable it. It encrypts files on a computer so that no one who has physical access to that computer can gain access to their contents. If the computer is stolen, no one would be able to read or view the contents of any of the files or images. It can be implemented on a file, directory or whole-drive basis. It is possible to enable certain EFS settings via Group Policy in Windows domain network setups. Users are provided with the recovery certificates and private keys that are used to encrypt and gain access to the files.
Encrypting File System -

Group Policy -
Encrypting files is simple, you just have to right-click on the file or folder or drive (in My Computer or Computer) that you want to encrypt, open Properties and enable the relevant check box.
EFS support is not available on all of the Home editions of very version of Windows from XP to Windows 10. There are no workarounds or hacks to enable it. If any Windows Home users want to make use of EFS, they have to upgrade to a Pro or higher edition of Windows. However, it is possible to set up file sharing or remote-desktop access on a local network to share access to unencrypted files.
Share files in File Explorer [Win10] -
How to use Remote Desktop - Applies to Windows 10 -
If you want to share encrypted data between different editions of Windows, say, between Windows 10 Home edition and Windows 10 Pro, you can use a third-party encryption tool, which would be just as secure as EFS and would work on all current versions and editions of Windows.
For example, you could use the free 7-Zip to encrypt all of the files and folders that you want to protect on your computer or stored online on, say, by using Microsoft's OneDrive storage facility that is provided with a Microsoft account, such as one created at Outlook.com. If you have files that contain sensitive information, you should always encrypt them before storing them online.
7-Zip - http://www.7-zip.org/
7-Zip uses AES-256 encryption that cannot be cracked as long as a strong password is used. The files can be accessed and decrypted while using any edition or version of Windows from Windows XP to Windows 10.

January 3, 2016. - Internet Service Providers (ISPs), such as the British companies BT, Sky, Virgin Media, Plusnet, etc., provide broadband customers with a modem router that can be used as a networking device for cabled and Wi-Fi connections and connect to the web via its modem. However, these modem routers are usually inexpensive devices that are not up to the Wi-Fi demands that many users require of them.
Fortunately that problem is easy to solve by buying a dedicated router that does not have a modem, is connected to a broadband modem router and can handle the Wi-Fi demands of many devices - desktop and laptop PCs, tablets, smartphones, printers, Blu-ray disc players, wireless Network Attached Storage (NAS) devices, etc. - and video-streaming services, such as Netflix and Amazon Prime in the UK.
Both modem routers and dedicated routers can be purchased, both can be connected to cabled and wireless devices, but only a modem router can go online using its cable or ADSL modem. The UK telephone landlines require the use of an ADSL modem for a broadband connection. Cable and superfast fibre broadband connections are also available that require their own types of modem router in order to connect multiple devices to the web and a wired/wireless network.
The latest wireless network standard is 802.11ac. Earlier standards are 802.11b, 802.11g and 802.11n that became available in that order. Here is the information that Wikipedia provides on the 802.11ac standard:
Wikipedia: "IEEE 802.11ac is a wireless networking standard in the 802.11 family (which is marketed under the brand name Wi-Fi), developed in the IEEE Standards Association process, providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. The standard was developed from 2011 through 2013 and approved in January 2014."
IEEE 802.11ac -
Currently, the best dedicated multiple-user router is the Linksys WRT1900ACS multiple-user model - currently priced at L180.00 - that supports all of the Wi-Fi standards - 802.11b/g/n/ac - which means that no wireless device needs to be discarded or all devices can be upgraded to the fastest 802.11ac standard. This router also provides many features that ISP-supplied router modems do not, such as the ability to connect to multiple devices simultaneously (older routers can only serve one device at a time) and be set to priorities them. It comes with an Ethernet cable that connects it to a modem router. An image of it is shown below.
There are apps that make customisation of devices that use Apple's iOS and Google's Android mobile operating systems easy.
Among this router's other useful features is an eSATA port that can be used to connect an external SATA hard disk drive that can be used as a Network Attached Storage (NAS) device that can be used as a file server or video-streaming device instead of using a Wi-Fi NAS.
Visit the following page on the Linksys site to find out the features that it provides.
Here is a good YouTube video review:
An alternative, cheaper (L150.00) dedicated router is the Linksys EA8500 Max-Stream AC2600 MU-MIMO Smart Wi-Fi Router.
