Is your PC very slow to start, your applications crash constantly, you can’t install Windows updates? This small, free and easy-to-use software can solve your problems.
Windows is a complex and delicate machine whose cogs can seize up, leading to a variety of bugs and malfunctions that are more or less annoying. Among the elements necessary for the proper functioning of Windows, system files are both essential and very fragile components, which can unfortunately be damaged and cause problems. Slow computer startup, unresponsive taskbar, cryptic error messages or updates that do not install are all signs that can indicate corrupted system files.
We have already introduced you System File Checkeror SFC, a handy tool built into Windows (and therefore free) that lets you check the status of system files and repair them if there are any problems, 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 corrupted 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.
Called DISM, for Deployment Imaging and Servicing Managementor Deployment Image Servicing and Management in French, this small toolbox also allows you to analyze and repair Windows, but does so on a different scale. In a simplified way, 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 solve problems with applications that crash or error messages that appear, 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 has developed a small utility called DISM-Guiwhich you can download for free via this linkand which allows you to enjoy DISM functions through a very simple graphical interface. The program is portable, that is to say, it does not even require installation. Above all, it is very simple to use with a few buttons that you just have to click.
If you have a persistent problem that SFC can’t seem to fix, then launch DISM-Gui and start by clicking on Check Then Scan to see if the program detects errors with system files. If so, then click the button Restore to perform a restore of corrupted components, from a healthy Windows image that DISM will recover online. Finally, click on the button SFC Scan to re-run 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!
