00:00Welcome to the definitive 2026 guide for Windows System Repair.
00:04Even with modern advancements, system corruption can still cause unexpected crash and slow performance in your workspace.
00:12Before you even think about formatting your drive and losing your data, there are two powerful, built-in tools that
00:19can fix almost any integrity issue.
00:21Let's dive in.
00:22The first line of defense is the System File Checker, or SFC.
00:26This tool scans all protected system files and replaces corrupted ones with a cached copy.
00:32To start, click on the search bar and type CMD.
00:35It is absolutely critical that you right-click the command, prompt and select Run as Administrator for full access.
00:42In the dark console window, type SFC, then a space, followed by a forward slash and a word scanner.
00:49Press Enter to initiate the verification process.
00:52The system will now begin a multi-stage scan.
00:55It checks the digital signature of every critical file to ensure they haven't been modified or damaged by software errors.
01:03This can take several minutes.
01:04If SFC finds a problem, it will automatically pull a healthy version of the file from the Windows Component Store
01:11to fix it.
01:12Once the verification reaches 100%, you'll see a report.
01:16If it says it found corrupt files but was unable to fix some, don't worry.
01:21That's our next step.
01:23Sometimes the local cache itself is damaged.
01:25For this, we use DISM, which stands for Deployment Image Servicing and Management.
01:31It's the ultimate repair tool.
01:33Back in the Administrator command prompt, type, DISM, then a space, forward slash online, space, forward slash, cleanup image, space,
01:43forward slash, restore health.
01:45This command is different because it connects to Windows Update.
01:48It downloads fresh, original files directly from Microsoft's servers to replace your corrupted local image.
01:56This process requires an internet connection.
01:59It might appear to hang at certain percentages, like 20 or 40%, but be patient and let it finish.
02:05When the operation completes successfully, your core Windows files are now in a perfect, factory-fresh state, even if you've
02:13been using the system for years.
02:15Now that the image is repaired, we run the SFC scan one last time.
02:19This ensures that the newly downloaded healthy files are correctly placed in your active system.
02:25Finally, we need to reboot.
02:27A restart clears out temporary data and allows Windows to initialize the newly repaired files upon startup.
02:33Watch how quickly the system loads, the interface is snappy, the errors are gone, and your PC is running exactly
02:41as it did the day you bought it.
02:42By using SFC and DISM, you've saved your system without the hassle of a full reinstallation.
02:49Keep these commands in your toolkit for future maintenance.
