How To Use System File Checker to Repair Files on Windows 10

If you notice some random errors on your Windows or while booting up there occurs some issues then there is very good chance that the System Files and Folders present  are corrupted.

Windows 10 has been pretty good in handling the files required for proper functioning compared to its older versions however the instability occurs when there is a Windows Update.

So in order to check whether your system has corrupted files Windows 10 has a built-in System File Checker which is a command-line utility that automatically scans and repairs corrupted files if present any, with a proper and stable version.

Here’s a step-by-step guide on using this service:

Implementing SFC:

  1. Click on Windows icon on bottom left-> search Command Prompt.
  2. Right Click on Command-Prompt->Select Run as Administrator also called as elevated command prompt.
  3. Now type sfc /scannow (Note that there is a space in between).
  4. Wait for the process to complete as this might take some time.

After the process gets 100% completed look in the Command Prompt screen

  • If you get a message as displayed below then there were some file errors which were detected and restored.

Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not supported in offline servicing scenarios.

  • And if the message is displayed like the one below then there were no problems detected with the files.

Windows Resource Protection did not find any integrity violations.

  • If message displayed is like the one below then Windows was not able to repair those files.

Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log.

Note: If there were any repairs made by the System File Checker then Restart your device as the SFC might not prompt you to do so.

Did you notice CBS.log which is mentioned whenever errors are detected?This is a LOG file where list of all the corrupted files which were restored or not are saved.

So if you want to check the list of files here’s how you can access it , go to C:\Windows\Logs\CBS\CBS.log. If you want to analyse the files check out on  How To analyse the Log Files created by SFC

Conclusion:

The Built-In System File Checker is one the best tools you can use to view corrupted files however if you’re not satisfied you can always try and implement the third party software available online.

 

What Is Virtualization?

Virtualization is a term used when a software application is used as a  hardware emulator

How Virtualization works:

When software is installed on the host device , the operating system of the host device which usually communicates with its real hardware is now communicating with with software emulator of the same hardware.

Though the performance of virtual system is not as good as the real one, it is used because most host devices do not require full participation of hardware

Initially coined for Server Virtualization the concept is used for desktop,data and network virtualization.

Benefits of  virtualization:

1) Run Apps Supported by Different OS:

Having a Windows OS and want to run application supported on Linux or vice-versa, download from CD in case of Windows and from online if the OS you need is Linux, now install the required OS on the Virtual Machine and then download required app  [What Is Virtual Box]

This is how it will appear


2.Access to Virus-Infected Data:

Having a file which your antivirus software has flagged but you have to access it anyway?With the help of virtualization you can access virus infected files .

VM comes with a snapshot functionality which saves the state of all your hardware and virtual OS like freezing time.

So while accessing your file if the virus causes havoc,just click the restore VMoption Viola! Clean virtual computer.

Using the same functionality you can test software upgrades & new configurations

TYPES OF VIRTUALIZATION:

1: Server Virtualization 

Most servers operate at less than their full  capacity resulting in waste of expensive hardware resources .  Server virtualization improves these inefficiencies by allowing multiple operating systems to run on a single physical server as virtual machines, multiplying the capacity of every single physical machine.

Software : VMware vSphere

2:Network Virtualization:

Network virtualization is the complete replica of physical network.It consists logical networking devices – i.e. logical ports,logical switches,firewalls,router and more.Virtual networks offer same features as the physical network but with hardware independence

Here you can see multiple x-86 processors replaced by single x-86 with multiple VM.

*Hypervisor is a virtual machine manager which creates and runs virtual machines.

Software: Apache:Openstack and VMware NSX

3: Desktop Virtualization

In today’s time-efficient world everyone wants to access their data from anywhere across the globe so that their work does not meet hurdles

This is where desktop virtualization comes into picture.With the use of Remote Desktop Services employee is given a virtualized computer with company’s data being saved on a central server.Thus employee is able to access it’s data by simply logging in the central server .

Even if the employees computer is damaged all the data can be recovered from company’s central server instead of repairing individual computer of employee.

The access of employee can be can be restricted by restricting the access of the virtualized computer to the central server.

Disadvantage is that if the security of server is breached all the data of the central server is at risk thus privacy of central server is of the utmost importance

Software: VMware Horizon

Add useful commands to Windows right click menu

Using context menu is the quickest way to do certain tasks on Windows-based PCs. You can immediately access a software, execute a command or do edit operations from right-click menu.

The right-click menu or context menu already has the wide range of useful options, but there might be some things to which you need quick access.

Earlier we used to do it by editing registry and going through some complex procedure and the procedure used to differ for different Windows versions. But when you are using a software to do it, it becomes all much easier and quicker.

Easy Context Menu is one such free software which can be used on all latest Windows systems. When you start the program you will see a list of commands ready to be added to different context menus.

Easy Conext Menu

All the options shown are self-explanatory, you just need to select the options that you want to add to context menu. You can read more about this over here

Easy Context Menu is compatible with Windows 7 and Windows Vista (32-bit + 64-bit both). You can download this small free software from the link given below.
