Make Windows go faster and faster

The following directions, if completed on a regular basis, will allow your computer to run at its optimal speed. Performance is greatly reduced over time, due to the accumulation of spyware, unnecessary files, a disorganized hard drive, and worst of all… viruses!


I. Temporary Internet Files

Every time you surf the internet, order something online, or read e-mail, information is stored on your computer for later use. Over time, this junk accumulates and eventually influences the performance of your computer.

6) Click the Uninstall/Change button towards the top of the window.

Review of Oracle VM Virtual Box - Windows inside a window


Its Very amazing thing to know that we can run a window in other windows without restart i.e multiple windows at same time. For this We Need a software Named As Virtual Machine and One of the Most Popular Virtual Machine is Oracle VM VirtualBox. It is Very good software of people who used multiple type of operating windows as their profession or education purpose.

Oracle VM VirtualBox! 
  VirtualBox is a cross-platform virtualization application. What does that mean? For one thing, it installs on your existing Intel or AMD-based computers, whether they are running Windows, Mac,  Linux or Solaris operating systems.     Secondly,  it extends the capabilities of your existing computer so that it can run multiple operating systems (inside multiple virtual machines) at the same time. So, for example, you can run Windows and Linux on your Mac, run Windows Server 2008 on your Linux server, run Linux on your Windows PC, and so on, all alongside your existing applications.  You can install and run as many virtual machines as you like – the only practical limits are disk space and memory. 
  VirtualBox  is  deceptively  simple  yet  also  very  powerful. It  can  run  everywhere  from  small embedded  systems  or  desktop  class  machines  all  the  way  up  to  datacenter  deployments  and even Cloud environments.

Why is virtualization useful? 

The techniques and features that VirtualBox provides are useful for several scenarios: 
  • Running multiple operating systems simultaneously. VirtualBox allows you to run more than  one  operating  system  at  a  time.   This  way,  you  can  run  software  written  for  one operating system on another (for example, Windows software on Linux or a Mac) without having to reboot to use it. Since you can configure what kinds of “virtual” hardware should be presented to each such operating system, you can install an old operating system such as  DOS  or  OS/2  even  if  your  real  computer’s  hardware  is  no  longer  supported  by  that operating system. 
  • Easier software installations.Software vendors can use virtual machines to ship entire software configurations.  For example, installing a complete mail server solution on a real machine can be a tedious task.  With VirtualBox, such a complex setup (then often called an “appliance”) can be packed into a virtual machine. Installing and running a mail server becomes as easy as importing such an appliance into VirtualBox. 
  • Testing and disaster recovery. Once installed, a virtual machine and its virtual hard disks can be considered a “container” that can be arbitrarily frozen, woken up, copied, backed up, and transported between hosts. 
  • Infrastructure consolidation.  Virtualization can significantly reduce hardware and elec- tricity costs. Most of the time, computers today only use a fraction of their potential power and run with low average system loads.  A lot of hardware resources as well as electricity is thereby wasted. So, instead of running many such physical computers that are only par- tially used, one can pack many virtual machines onto a few powerful hosts and balance the loads between them.


Key Features
Here’s a brief outline of VirtualBox’s main features: 

  • Portability. VirtualBox runs on a large number of 32-bit and 64-bit host operating systems 
  • VirtualBox is a so-called “hosted” hypervisor (sometimes referred to as a “type 2” hypervisor).  Whereas a “bare-metal” or “type 1” hypervisor would run directly on the hardware,VirtualBox requires an existing operating system to be installed.  It can thus run alongside existing applications on that host. 
  • To a very large degree, VirtualBox is functionally identical on all of the host platforms, and the same file and image formats are used. This allows you to run virtual machines created on one host on another host with a different host operating system; for example, you can create a virtual machine on Windows and then run it under Linux. 
  • In addition, virtual machines can easily be imported and exported using the Open Virtual- ization Format  and exporting virtual machines,  an industry standard created for this purpose. You can even import OVFs that were created with a different virtualization software. 
  • No hardware virtualization required. For many scenarios, VirtualBox does not require the  processor  features  built  into  newer  hardware  like  Intel  VT-x  or  AMD-V.  As  opposed to  many  other  virtualization  solutions,  you  can  therefore  use  VirtualBox  even  on  older hardware  where  these  features  are  not  present.  
  • Guest Additions: shared folders, seamless windows, 3D virtualization. The VirtualBox Guest  Additions  are  software  packages  which  can  be  installed  inside  of  supported  guest systems to improve their performance and to provide additional integration and communi- cation with the host system. After installing the Guest Additions, a virtual machine will sup- port automatic adjustment of video resolutions, seamless windows, accelerated 3D graphics and more.


Great hardware support. Among others, VirtualBox supports: 
  1. Guest multiprocessing (SMP). VirtualBox can present up to 32 virtual CPUs to each virtual machine, irrespective of how many CPU cores are physically present on your host. 
  2. USB device support. VirtualBox implements a virtual USB controller and allows you to connect arbitrary USB devices to your virtual machines without having to install device-specific drivers on the host.  USB support is not limited to certain device cate- gories. For details, see chapter 3.10.1, USB settings, page 49. 
  3. Hardware compatibility. VirtualBox virtualizes a vast array of virtual devices, among them many devices that are typically provided by other virtualization platforms. That includes IDE, SCSI and SATA hard disk controllers, several virtual network cards and sound  cards,  virtual  serial  and  parallel  ports  and  an  Input/Output  Advanced  Pro-  grammable Interrupt Controller (I/O APIC), which is found in many modern PC systems. This eases cloning of PC images from real machines and importing of third-party virtual machines into VirtualBox. 
  4. Full ACPI support.  The Advanced Configuration and Power Interface (ACPI) is fully supported by VirtualBox. This eases cloning of PC images from real machines or third party virtual machines into VirtualBox.  With its unique ACPI power status support, VirtualBox can even report to ACPI-aware guest operating systems the power status of the host.  For mobile systems running on battery, the guest can thus enable energy saving and notify the user of the remaining power (e.g. in fullscreen modes). 
  5. Multiscreen  resolutions.      VirtualBox  virtual  machines  support  screen  resolutions many times that of a physical screen, allowing them to be spread over a large number of screens attached to the host system. 
  6. Built-in iSCSI support.  This unique feature allows you to connect a virtual machine directly to an iSCSI storage server without going through the host system.The VM accesses the iSCSI target directly without the extra overhead that is required for virtu- 
  7. alizing hard disks in container files.  
  8. PXE Network boot.  The integrated virtual network cards of VirtualBox fully support remote booting via the Preboot Execution Environment (PXE). 

  • Multigeneration  branched  snapshots. VirtualBox  can  save  arbitrary  snapshots  of  the state of the virtual machine. You can go back in time and revert the virtual machine to any such snapshot and start an alternative VM configuration from there, effectively creating a whole snapshot tree.
  •   Clean  architecture;  unprecedented  modularity.  VirtualBox  has  an  extremely  modular design with well-defined internal programming interfaces and a clean separation of client and  server  code.   This  makes  it  easy  to  control  it  from  several  interfaces  at  once: for example,  you  can  start  a  VM  simply  by  clicking  on  a  button  in  the  VirtualBox  graphical user interface and then control that machine from the  command line,  or even remotely. 

On top of this special capacity, VirtualBox offers you more unique features: 

  • Extensible RDP authentication. VirtualBox already supports Winlogon on Windows and PAM on Linux for RDP authentication. In addition, it includes an easy-to-use SDK which allows you to create arbitrary interfaces for other methods of authentication; 
  • USB over RDP. Via RDP virtual channel support, VirtualBox also allows you to connect arbitrary  USB  devices  locally  to  a  virtual  machine  which  is  running  remotely  on  a VirtualBox RDP server.
