Bypass NTFS File Permissions

Friday, May 1st, 2009

I knew it would be possible to write a program to run as a system service and allow me bypass NTFS file permissions, but I hoped I could find a way to do it a lot simpler, and I’ve finally found it.

CREATE THE SERVICE WITH THIS COMMAND: (Copy and paste this as one line)
sc create SuperCMD binPath= “C:\WINDOWS\system32\cmd.exe /c c:\windows\system32\cmd.exe” type= own type= interact

START THE SERVICE WITH THIS COMMAND:

sc start SuperCMD

The first command pretty much registers CMD.exe starting CMD.exe as a system service, and allows it to interact with the desktop so you can see it. The second command starts the service, which really opens up a command prompt running with system privileges, thus allowing you to navigate into folders that you don’t have permission to enter. The second command will give an error, but as long the little black box is open, it doesn’t matter.

You can also run programs as the system account by typing the name of the program (sometimes you’ll need the full path), but explorer.exe will open as your regular user account, so if you want a GUI file manager, you’ll have to find something else. I actually used 7-Zip since since it was already installed on my computer and it worked fine.

This is a big help when working with customer’s hard drives as I can easily go through their profiles to remove malware files (with some special vb scripts I will release open sourced someday) or for copying their files to a FAT32 partition when Windows needs re-installed from scratch or a blank hard drive.

Computer Maintenance Made Simple

Computer Maintenance Made Simple

Just like cleaning is an important part of any maintenance procedure, whether it is your automobile or whether it is your house, it is important for you to cleanup your PC while performing computer maintenance as well. In this article, we are going to discuss a few handy tools that enable you to cleanup your PC and maintain it in a good working condition.

Registry Cleaner Tool

The Windows registry is like the brain of your Windows PC. Even a small activity, such as browsing the Web or opening a Word document, affects the registry in some way or another. As your PC grows older, the registry, where all configuration information of your system is stored, gets cluttered with loads of outdated, obsolete, and incorrect data. This digital junk causes your registry to grow at an uncontrollable speed, eventually damaging it. A damaged registry generates frequent system errors and causes system freezes and crashes.

To fix registry errors and free it from all the junk data, you need to use a reliable and efficient registry utility. Using a registry utility, you can perform several registry repair tasks, such as scan, detect, and remove unwanted files, defrag the registry to make it contiguous, and create regular registry backups that can be restored easily if the registry fails.

Disk Cleanup Tool

Just like the registry, your hard disk also bears the load of unwanted program installation files, obsolete temporary files, and loads of other outdated, unwanted files and folders. The Disk Cleanup tool that is shipped with your Windows XP operating system is one tool that you can use to get rid all this unwanted data in one go. The Disk Cleanup tool also enables you to uninstall unwanted applications and Windows components, delete obsolete System Restore snapshots and compress old files.

To start the Disk Cleanup tool, open the Start menu, select All Programs, select Accessories, select System Tools and then select Disk Cleanup.

After you have cleaned your hard disk with the Disk Cleanup tool, you may use the Disk Defragmenter tool—also available in System Tools—to analyze your hard disk for fragmented files and make them contiguous.

Windows Uninstaller Tool

The Add or Remove Program option available in Windows systems to uninstall applications from your system, usually fails in completely removing the applications. To counter this problem, many advanced third-party tools are available on the Internet. These tools come in handy when you are cleaning up your PC. They work by scanning your entire system and registry for any files and folders related to the program you want to uninstall, and enable you to delete them, and to completely get rid of the application you are uninstalling.

Antivirus and Antispyware Tools

Last but not least, the PC cleanup process requires you to scan your system for any malicious files and registry entries added by malware programs, such as virus, Trojans, worms, spyware and aware, and delete them. In order to perform these tasks, you need to use the Antivirus and Antispyware tools. You must always keep these tools updated with the latest virus definitions to ensure that your PC is protected against the latest threats. It is also recommended that you opt for tools that provide you with the real time protection feature. This feature, as the name implies, works in real time and blocks malicious files from infiltrating your system.

Using the above tools regularly not only helps you in maintaining a PC free from junk, but also enables you to enjoy an excellent computing experience for a long time to come.
