Windows Operating System:
On June 30, 1998 Microsoft released 'Windows 98', the successor to Windows 95.
On June 30, 1999 Windows 98 reached it's Second Edition (Windows 98 SE), requiring 24MB RAM,
in a step towards unification under a future version of Windows.
On December 31, 2000 Microsoft released Windows Millennium Edition (Me),
mainly a multimedia upgrade to Windows 98.
Windows XP, Windows Vista, Windows 7:
On December 31, 2001 Microsoft released
mainly an advanced multimedia upgrade to Windows Me on new 32 bit code (DOS is now an emulation),
with important new firewall-like security features in its version SP2.
The original Windows XP was supported until August 30, 2004.
Upgrade your Windows XP to the SP3 version (Service Pack 3) that is available from May 7, 2008.
On Windows XP new security updates are only available for versions SP2 and SP3.
Service Packs 2 and 3 are free, but are only available automatically to legitimate Windows XP users.
The last update was released on April 8, 2014.
Determine what versions of Windows 7 your PC can run using the program Windows 7 Upgrade Advisor. Windows 7 requieres modern processors (at least 1 GHz) and SVGA graphics processors, and 1 GB of RAM. Also a DVD-ROM drive is required for installation.
To install a 64-bit version of Windows 7, you need a CPU that's capable of running a 64-bit version of Windows. The benefits of using a 64-bit operating system are most apparent when you have a large amount of random access memory (RAM) installed on your computer, typically 4 GB of RAM or more. In such cases, because a 64-bit operating system can handle large amounts of memory more efficiently than a 32-bit operating system, a 64-bit system can be more responsive when running several programs at the same time and switching between them frequently.
Microsoft made Windows RT
(a version of Windows 8 that does not run Windows XP or Windows 7 programs) available on
new PCs and Surface tablets
on October 26, 2012.
Within the first 24 hours of Windows 10's release on July 29,
Microsoft said its newest operating system was installed on 14 million devices.
Windows 10 - Free Upgrade Offer:
Great news! We will offer a free upgrade to
for qualified new or existing Windows 7, Windows 8.1 and Windows Phone 8.1 devices that upgrade in the first year!
Search for anything, anywhere, in your PC and the web from the taskbar to find help, apps, files, settings-you name it.
Your intelligent personal assistant
Cortana will be your guide.
Microsoft Edge, Windows 10's new default web browser, doesn't support ActiveX, DirectX filters, VML vector graphics, or VBScript. But upgrading to Windows 10 doesn't mean your organization's legacy web apps won't work.
To ensure that Windows 10 was compatible with older applications (such as those that require an ActiveX control), Microsoft included Internet Explorer 11 with the new operating system. However, before you can run ActiveX controls safely, you'll need to tweak IE 11's settings.
See The trick to running legacy web apps on Windows 10 (TechRepublic, Ant Pruitt. December 2, 2015)
[To see the DirectX diagnostics for your graphics card, run the command "dxdiag" (from the Windows Start button) and select the System and Display tabs]
Physical Address Extension (PAE), NX processor bit (NX), and Streaming SIMD Extensions 2 (SSE2) are features of the processor, and they're needed to run Windows 8.1 and Windows 10.
Updates automatically download and install when they're available - which means that your PC always has the latest and best features.
If it's been less than 31 days since you upgraded to Windows 10, you won't get the November update right away; this will allow you to go back to your previous version of Windows if you choose. After the 31 days have passed, your PC will automatically download the November update.
Windows 10 periodically checks for updates. If you want to check for the update now, select the Start button, then select Settings > Update & security > Windows Update > Check for updates.
Here's how to make it stop:
The settings for the new Peer-to-Peer (P2P) option default are for sharing updates with other computers over the Internet,
not just those on your network, using your upload bandwidth and slowing down your network connection.
From How to stop Windows 10 from using your PC's bandwidth to update strangers' systems (PCWorld, Aug. 3, 2015)
If your PC clone came with an illegal copy of Windows, you can buy and install an original without loosing your installed programs or your documents.
If you can not install and keep updated a legal copy of Windows,
it is a matter of time before your vulnerabilities will be exploited, even if you expertly use a complete firewall program.
From September 28 to November 15, 2006, 90% of oarval.org visitors were using Windows, but 13% of them had unsupported versions.
Simultaneously, we are hard at work on the next release of the Office desktop suite that will be called Office 2016.
See The next chapter of Office on Windows (Office Blogs. January 22, 2015).

Linux Operating System:
For years, Linux has dominated supercomputing. The November 2014 Top 500 supercomputer ranking found 485 out of the world's fastest 500 computers running Linux (97%). UNIX, which once dominated the bi-annual listings is down to a mere 13 systems (2.6%). One system runs Windows, and the other a mix.
See Linux still owns supercomputing (Steven J. Vaughan-Nichols. November 18, 2014, ZDNet)
Ubuntu is a complete Linux-based operating system, freely available with both community and professional support.
Ubuntu is suitable for both desktop and server use.
The current Ubuntu release supports 32-bit PCs (Intel x86), 64-bit PCs (Intel x64/AMD64),
Sun UltraSPARC and T1 (Sun Fire T1000 and T2000), PowerPC (Apple iBook, Powerbook, G4 and G5) and OpenPower (Power5) architectures.
Lubuntu is a variant of Ubuntu that is lighter,
less resource hungry and more energy-efficient, using lightweight applications and LXDE,
the Lightweight X11 Desktop Environment, as its default Graphical User Interface.
On the 'Desktop ISO', the graphical installer Ubiquity requires about 800 MB of RAM to run.
Xubuntu looks like a typical linux distro,
based on the extremely light XFCE desktop environment and super-fast.
Xubuntu is for those who have low RAM old systems.
Kubuntu is a good looking distro based on the KDE desktop environment.
Those who prefer Windows would definitely like it.
It is slightly heavier than Xubuntu though almost equally fast on a low resource system.
Edubuntu is an education-oriented operating system.
Warning: Creating partitions is a delicate operation, that could result in the loss of the data on your hard drive.
Wubi is an officially supported installer for Windows XP, Vista and 7 that allows Ubuntu (or any of its interfaces) to be installed and uninstalled in a safe, easy way as with any other Windows application, without creating a new partition. The installed version is accessed as an alternative at the starting of the PC. At this time Wubi does not work with Windows 8 default boot-loader.
Samba is a suite of programs that enables interoperability between Linux/Unix servers and Windows clients. "Samba is an Open Source/Free Software suite that provides seamless file and print services to SMB/CIFS clients." Samba is freely available, unlike other SMB/CIFS implementations, and allows for interoperability between Linux/Unix servers and Windows-based clients.
Wine Allows you to run many Windows programs on Linux.
An Ubuntu 32-bit version will be faster than the 64-bit version with less than 2 GB of RAM.

Google Chrome Operating System:
The Google Chrome Operating System, also known as Chrome OS, is the first operating system for the cloud computing era. The Chrome OS is a web-based operating system, in that it relies on a variety of web-based services and applications to work; it doesn't run traditional desktop applications.
Chrome is an open source operating system, which means that it can be freely distributed without paying expensive licensing costs. It is based on a version of Linux, another operating system that itself is based on the established UNIX operating system.
The Chrome OS interface runs on top of the Linux kernel. The interface strongly resembles Google's Chrome web browser; there is no traditional desktop, as found in Microsoft Windows or Apple's Mac OS. Applications are launched in individual tabs within the Chrome browser; system operations are accessed from a single Command and Control menu. Using Chrome OS is more like browsing the Web than it is navigating a complex operating system.
If you've used the Google Chrome web browser, Chrome OS is going to look and feel very familiar. Using Chrome OS is almost identical to using the Chrome browser, complete with its multiple tabs and Address Box. The big difference is that Chrome OS not only displays web pages in its tabs, but also web applications and system operations; you use the Chrome OS Address Box to enter and search not only web URLs but also web applications. It is designed to be used on small portable computers, known as Chromebooks, which are wirelessly [or wired] connected to the Internet.
From Michael Miller, My Google Chromebook (Amazon Books. Kindle and paperback editions)
Chromebooks are a new type of computer. They're fast to use, and don't slow down over time. They have built-in security, so you're protected against viruses and malware. They come with applications for all your everyday needs, and keep your data and software safely backed up on the cloud. Since June 2011 they are being manufactured by Samsung, Acer and HP.
See Chromebooks (at Google.com)
CloudReady, from Neverware, is a lightweight operating system built on the same foundation as Google's Chrome OS, but able to run on almost any hardware.
Chromium was built without broad hardware support. CloudReady makes it run on virtually any machine by providing a single installer image with broad driver support and compatibility fixes.
CloudReady only runs one thing: a browser. This makes for a bloat-proof and lightweight OS that can keep machines up to 8 years old fast and responsive.
You don't have to settle if you want a headache-free Linux distribution. CloudReady is an alternative to other Linux distributions that gives you a clean, modern, and unobtrusive desktop.
CloudReady is Fast, Beautiful and Free.
Asymmetric Digital Subscriber Line (ADSL or DSL):
Java is a free computer programming tool and software platform used by every browser in the Internet,
and many Web sites.
It has been developed by Sun Microsystems since 1991,
and in 1995 it appeared the Web with the Netscape Navigator browser. Java brings animated interactivity to Web pages.
The most severe Secunia advisory affecting Oracle Java JRE 1.7.x / 7.x, with all vendor patches applied,
is rated Extremely Critical: Update to version 7 update 11.
Oracle recommends updating your Java to version 7 update 13, with Java Control Panel maximum security settings. But I still recommend to prevent it for working under you browsers (from the Control Panel), if you don't need it.

The program runs in the background, taking up minimal memory and Net resources.
It's simple. When you install ICQ, the program asks you to register at a server, which is connected to a broad network of servers spanning the Internet. At the time of registration, you receive a unique UIN (Universal Internet Number). In addition, ICQ gives you the option of entering personal information along with your UIN. This allows other ICQ users to recognize you when you log on.
Once you've registered, you can compile a selected list of friends and associates. ICQ uses this list to find your friends for you. Meanwhile, ICQ waits quietly in the background without interrupting any other applications in use. As soon as you log onto the Internet, ICQ automatically detects the Internet connection, announces your presence to the Internet community and alerts you when friends sign on or off.
