Is your PC very slow to start up, your applications crash constantly, you can’t install Windows updates? This little free and easy-to-use software can solve your problems.
Windows is a complex and delicate piece of machinery whose cogs can seize up, leading to a whole variety of more or less annoying bugs and malfunctions. Among the elements necessary for the proper functioning of Windows, system files are both essential and very fragile components, which unfortunately can be damaged and cause problems. Slow computer startup, unresponsive taskbar, cryptic error messages or updates that fail to install are all signs that may indicate corrupted system files.
We have already presented to you System File Checkeror SFC, a handy tool built into Windows (and therefore free) that allows you to check the status of system files and repair them if something goes wrong, all from a simple text command. But sometimes SFC detects errors and is unable to correct them, which it indicates with this worrying message: “Windows Resource Protection found damaged files, but was unable to repair them all”. Fortunately all is not lost, because there is another Windows repair tool that you can use in addition to SFC.
Entitled DISM, for Deployment Imaging and Servicing Managementor Management and maintenance of deployment images in French, this small toolbox also allows you to analyze and repair Windows, but does it on a different scale. Simply put, SFC checks each system file individually, while DISM checks the overall structure of Windows, checking the integrity of the system image. In most cases, SFC will be able to resolve issues with applications crashing or error messages appearing, but if it fails, then DISM can take over.
Like SFC, DISM is a tool that is normally used in “text mode”, via the Windows Command Prompt or Terminal, which is not very convenient for most people. However, the excellent German specialist site Deskmodder developed a small utility called DISM-Guiwhich you can download for free via this linkand which allows you to benefit from DISM functions through a very simple graphical interface. The program is portable, that is, it does not even require installation. Above all, it is very simple to use with a few buttons that you just have to click on.
If you have a persistent problem that SFC cannot seem to resolve, launch DISM-Gui and start by clicking on Check Then Scan to see if the program detects errors with system files. If this is the case, then click on the button Restore to perform a restoration of corrupted components, from a healthy Windows image that DISM will recover online. Finally, click on the button SFC Scan to relaunch the tool of the same name. Thanks to the fixes made upstream by DISM, SFC may finally be able to repair the damaged system files on which it previously failed!
