"system analysis tool"

[Gt-truth]

It's the time to develop a new thing called "system analysis tool" for us!Therefore, such a tool would be wonderful and useful for the analysis of our Windows systems in search for any suspicious system files / Windows system files are missing / corrupted Windows files!

How To Use SFC /Scannow to Repair Protected Windows Operating System Files

 

By Tim Fisher, About.com Guide

• command prompt commands
• sfc
• system file checker

The sfc scannow option is one of several specific switches available in the sfc command, the Command Prompt command used to run System File Checker. Sfc /scannow is the most common way that the sfc command is used.

 

Sfc /scannow will inspect all of the important Windows files on your computer, including Windows DLL files. If System File Checker finds an issue with any of these protected files, it will replace it.

 

Follow these steps for using sfc with the scannow option to repair important Windows files:

 

Difficulty: Easy

Time Required: Using sfc /scannow to repair important Windows files usually takes 5 to 10 minutes.

Here's How:

1. Open Command Prompt as an administrator, often referred to as an "elevated" Command Prompt.

   Important: For the sfc /scannow command to work properly, it must be executed from an elevated Command Prompt window in Windows 8, Windows 7 and Windows Vista. This is not required in previous versions of Windows.

2. Once Command Prompt is open, type the following command and then press Enter.

   sfc /scannow

   Note: There's a space between sfc and /scannow.

   Important: If you're trying to use System File Checker from the Command Prompt available from Advanced Startup Options or System Recovery Options, see Tip #1 at the bottom of the page for some changes in how you execute sfc /scannow.

3. System File Checker will now verify the integrity of every protected operating system file on your computer.

   Note: In some situations, especially in Windows XP and Windows 2000, you may also need access to your original Windows installation CD or DVD.

4. Restart your computer if sfc /scannow did actually repair any files.

   Note: System File Checker may or may not prompt you to restart but even if it doesn't, you should restart anyway.

5. Repeat whatever process caused your original problem to see if sfc /scannow corrected the issue.

Tips:

1. When running sfc /scannow from outside of Windows, like from the Command Prompt available when you boot from your Windows disc or flash drive, or from your System Repair Disc or Recovery Drive, you'll have to tell the sfc command exactly where Windows exists, as in this example:

   sfc /scannow /offbootdir=d:\ /offwindir=d:\windows

   The /offbootdir= option specifies the drive letter, while the /offwindir= option specifies the Windows path, again including the drive letter.

   Note: Depending on how your computer is setup, the Command Prompt, when used from outside of Windows, doesn't always assign drive letters in the same way that you see them from inside Windows. In other words, Windows might be at C:\Windows when you're using it, but D:\Windows from the Command Prompt in System Recovery Options.

2. In most installations of Windows 8 and Windows 7, C: usually becomes D: and in Windows Vista, C: is usually still C:. To check for sure, look for the drive with the Users folder on it - that will be the drive Windows is installed on, unless you have multiple installations of Windows on multiple drives.

Links to articles about using System File Checker (SFC) and many other helpful resources can be found here. Ron's compiled quite a handy list of tools and resources there.

There are already tons of those, so I don't think we will be using resources to develop one unless there's a need for it. DDS, OTL and other similar tools are quite capable and widely used at the moment and for troubleshooting our own software, we have mbam-check.exe.

whats up !

This mbam-check-tool is not even in the list of products and how can we know these things and you do not declare it in public?Just like Kaspersky, they have their own tool and have the support forum for this tool!

And you do not even have our own tool for gathering information and this is not acceptable to all and would like to see this tool very soon

 

If you want to expand and grow in your field of work and even the development of new software and tools then we can help you to develop software and new tools so that we can to track down a bug!

For many you have an only a few of the programs and tools compared to new/old companies and this is good for a company like Kaspersky and others!

And you do not even have portable protection programs, as is the case with other companies and should at least provide other solutions such as a rescue disk! For emergencies!

It's used frequently by our own Support team. It's of little use to anyone who doesn't know how to read the logs and interpret the information it provides.

We've done pretty well with what we have so far. We have unique offerings like Chameleon that often eliminate the kinds of problems that result in people resorting to bootable tools. I see little use of 'portable' tools at all because I know from experience that if a program is blocked from running on the system if installed locally, it's also going to be blocked from running from portable media such as a flash drive or CD.

We've been diversifying our offerings quite a bit, but we also don't want to stretch ourselves too thin. The entire reason we exist and have been so successful is because these larger vendors with all their great tools have failed to provide adequate protection from all of the nasty 0-day threats in the wild. By keeping our focus on what we do best while still expanding (though gradually) only when we are confident that we can continue to do our primary job of detecting the latest malware, we're able to stay on top of the bad guys instead of having tons of different tools and software that amount to little because they can't eliminate the latest infections. I don't see the decisions we've made up to this point as having hurt us. In fact, if anything, it's helped us. Our company and software has gained steadily in popularity, with more and more users turning up every day and we have a responsibility to them to continue to offer the best protection possible, so that is our primary area of focus.
