Alright, so you\’re having some issues with Windows 10, but you\’re really not in the mood to lose your precious files and applications. I get it, and luckily, there are a few ways to breathe some life back into your system without causing a data disaster.
Getting Started:
First things first, back up those important files! Just toss your key documents onto an external drive or cloud storage, because you can never be too safe. Check your hard drive space too – you don\’t want to run out of room mid-fix. Also, be sure you\’ve got the right Windows edition and language, just to keep everything running smoothly.
Plan A: In-Place Upgrade (Repair Install):
This one\’s kind of like hitting refresh on your Windows without touching your personal files or apps. You\’re swapping out the janky system files for shiny new ones. Here\’s what you do:
- Head over to Microsoft\’s site and snag the Windows 10 ISO or installation media.
- Open it up via File Explorer and fire up the setup.exe.
- When the options pop up, make sure to select “Keep personal files and apps.” That\’s the golden ticket to avoid unwanted data loss.
- Follow the on-screen cues. There\’ll be a few restarts, but once it\’s all done, your system files should be as good as new.
Plan B: Use DISM and SFC for Quick Fixes:
Feel like going the DIY route first? Check out DISM and SFC – these tools are like your built-in repair crew for Windows.
- Launch an elevated Command Prompt (just right-click Start and take it from there).
- Enter this command: dism /online /cleanup-image /restorehealth. This should patch things up using files from Windows Update.
- Once that\’s done, run sfc /scannow to take another sweep. Sometimes you have to rinse and repeat.
Plan C: Reset or Clean Install:
Still in the weeds? You might have to hit the reset button:
- Dive into Settings, then Update & Security, and head to Recovery. Look for “Reset this PC.” You can choose whether to keep your files, but heads up: most apps will vanish.
- If things are super messed up, a clean install might be your last resort. Just make sure that backup is solid, because this will wipe the slate clean.
A Few Extras:
If stuff like a busted Start menu or iffy context menus keeps cropping up, maybe it\’s time to double-check for malware. Make sure your antivirus is up and at \’em. Also, pause any major updates until things are stable.
So, there you go. By taking it step by step, you can hopefully sort out your Windows 10 woes and keep all your beloved data in one piece. Good luck!

Trying to fix your Windows 10 without losing everything? Don’t worry, it’s totally doable. Here’s how:
First Up: Use Windows 10 Installation Media
- Grab the Media Creation Tool: Head over to the Microsoft site and download their Media Creation Tool. This is the key to getting started.
- Make Some Installation Media: Use the tool to whip up a bootable USB drive or ISO file. You’ll need this for the repair.
- Fire Up Setup: Plug that USB into your computer and open File Explorer. Double-click on setup.exe inside the USB, and let’s get rolling.
- Go for the Upgrade: When it asks you what to do, pick “Upgrade this PC now.” This way, Windows repairs itself without messing up your files and apps.
- Wrap It Up: Just follow along with the prompts until everything is done. Before you know it, your Windows 10 should be back in shape.
Another Angle: Use SFC and DISM Tools
- Run the Command Prompt: Hit Win + X and pick Command Prompt (Admin) or Windows PowerShell (Admin).
- Try an SFC Scan: Type
sfc /scannow
and hit Enter. This checks and fixes corrupted system files for you. - Give DISM a Shot: If you’re still having trouble, type
DISM /Online /Cleanup-Image /RestoreHealth
and press Enter. This one digs a little deeper into the system issues.
These tricks should help sort out your Windows 10 woes while keeping your important stuff right where it is. Dive into the Microsoft Support pages for more nitty-gritty details if you need them.
