Portable application Wikipedia. A portable application portable app, sometimes also called standalone, is a program designed to read and write its configuration settings into an accessible folder in the computer, usually the folder where the portable application can be found. This makes it easier to transfer the program with the users preferences and data between different computers. A program that doesnt have any configuration options is also a portable application. Portable applications can be stored on any data storage device, including internal mass storage, a file share, cloud storage or external storage such as USB drives and floppy disksstoring its program files and any configuration information and data on the storage medium alone. If no configuration information is required a portable program can be run from read only storage such as CD ROMs and DVD ROMs. Some applications are available in both installable and portable versions. Some applications which are not portable by default do support optional portability through other mechanisms, the most common being command line arguments. Examples might include portable to simply instruct the program to behave as a portable program, or cfgpathinifile to specify the configuration file location. Like any application, portable applications must be compatible with the computer system hardware and operating system. Torrent Bigasoft Mkv Converter'>Torrent Bigasoft Mkv Converter. Depending on the operating system, portability is more or less complex to implement to operating systems such as Amiga. Install Virtualbox Without Admin Privileges In Vista' title='Install Virtualbox Without Admin Privileges In Vista' />OS, all applications are by definition portable. Portable apps are distinct from software portability, source code written to be compilable into different executable programs for different computing platforms. Portable Windows applicationseditA portable application does not leave its files or settings on the host computer or modify the existing system and its configuration. The application does not write to the Windows registry or store its configuration files such as an INI file in the users profile instead, it stores its configuration files in the portable directory. Another requirement, since file paths will often differ on changing computers due to variation in Windows drive letter assignments, is the need for applications to store them in a relative format. While some applications have options to support this behavior, many programs are not designed to do this. A common technique for such programs is the use of a launcher program to copy necessary settings and files to the host computer when the application starts and move them back to the applications directory when it closes. An alternative strategy for achieving application portability within Windows, without requiring application source code changes, is application virtualization An application is sequenced or packaged against a runtime layer that transparently intercepts its file system and registry calls, then redirects these to other persistent storage without the applications knowledge. This approach leaves the application itself unchanged, yet portable. The same approach is used for individual application components run time libraries, COM components or Active. X, not only for the entire application. As a result, when individual components are ported in such manner they are able to be integrated into original portable applications, repeatedly instantiated virtually installed with different configurationssettings on the same operating system OS without mutual conflicts. As the ported components do not affect the OS protected related entities registry and files, the components will not require administrative privileges for installation and management. Microsoft saw the need for an application specific registry for its Windows operating system as far back as 2. It eventually incorporated some of this technology, using the techniques mentioned above, via its Application Compatibility Database 3 using its Detours 4 code library, into Windows XP. It did not make any of this technology available via its system APIs. Portability on Linux and Unix like systemseditPrograms written with a Unix like base in mind often do not make any assumptions. Whereas many Windows programs assume the user is an administratorsomething very prevalent in the days of Windows 9. ME and to some degree in Windows XP2. Windows Vista or Windows 7such would quickly result in Permission denied errors in Unix like environments since users will be in an unprivileged state much more often. Programs are therefore generally designed around using the HOME environment variable to store settings e. HOME. w. 3m for the w. The dynamic linker provides an environment variable LDLIBRARYPATH that programs can use to load libraries from non standard directories. Assuming mnt contains the portable programs and configuration, a command line may look like HOMEmnthomeuser LDLIBRARYPATHmntusrlib mntusrbinw. A Linux application without need for a user interaction e. GCCLinker option ORIGIN which allows a relative library search path. Not all programs honor thissome completely ignore HOME and instead do a user look up in etcpasswd to find the home directory, therefore thwarting portability.

Locker encrypted drives with the manage bde command. Michael Pietroforte is the founder and editor of 4sysops. He is a Microsoft Most Valuable Professional MVP with more than 3. IT management and system administration. Latest posts by Michael Pietroforte see allA while back, I claimed that hard drives in business PCs should always be encrypted for various reasons. Even though many third party encryption solutions are available, Bit. Locker would always be my first choice because it is perfectly integrated into Windows. Unfortunately, by default this is not the case for Windows PE. A disadvantage of hard drive encryption is that you cant easily access the system drive for troubleshooting if Windows is unable to boot up properly. Imagine a high ranking manager coming to your office one morning, telling you that her laptop doesnt boot up and that she has important data on the encrypted system disk that she desperately needs later today. Ah, and by the way, her flight leaves in an hour. What will you do One option is to boot up from your Windows PE rescue USB stick, unlock the Bit. Locker encrypted drive, retrieve the important data, and be a hero. Another option would be to look for another job, but we wont pursue this problem solution here. To unlock a Bit. Locker encrypted drive from the command prompt, you need the Windows command manage bde. However, if you only have a common bootable Windows PE USB stick, your heroic deed will miserably fail with this error message ERROR An error occurred code 0x. Class not registered. Not nice if your impatient manager is looking over your shoulder, claiming that she has booked a business class flight that will not wait for her. To avoid this embarrassing situation, youd better have a Windows PE rescue stick at hand where all Windows PE WMI classes have been installed. To create a Windows PE installation that you can use to unlock Bit. Locker encrypted drives, you have to download the Windows AIK WAIK for Windows 7, install the WAIK, launch the Deployment Tools Command Prompt with admin privileges, and then follow this procedure Create a Windows PE WIM image to unlock Bit.

Under Windows 7, you can create the bootable Windows PE DVD through the context menu of the ISO file. Download Tricks In Checkers Game on this page. I have already explained in detail how to create a bootable Windows PE USB stick before, so I wont repeat this procedure here. Unlock Bit. Locker with manage bde Once you have booted up Windows PE, you can unlock the Bit. Locker encrypted system drive with this command. I assume here that you have stored all Bit. Locker recovery keys either in Active Directory or at another safe place. Of course, without a recovery key, you cant access a Bit. Locker encrypted drive from a second Windows installation. After all, that is the point of encrypting hard drives. Tip Copy the recovery key file to your USB stick before you boot up. Then you can open the recovery key file with Notepad and paste the key on the command line. Manage bde also has the recoverykey parameter, which is supposed to allow you to read the recovery key file from a drive. However, when I tried this option I only got this error message ERROR An error occurred while attempting to read the key from disk. I got the same error message under Windows 7, so I somehow think there is a bug involved because the recovery key worked fine. Please let me know if this option worked for you.
