How to Fix Windows 11 Update & Installation Errors (Step-by-Step Guide)”

If your Windows 11 updates keep failing or installation gets stuck, you’re not alone. Many users face issues like “Windows Update failed to install”, error 0x800f0922, or endless update loops. Fortunately, you can fix most of these problems with a few simple Command Prompt (CMD) commands — no need to reinstall Windows!

Follow this step-by-step guide carefully, and you’ll have your Windows 11 system running smoothly again.

🔹 Step 1: Stop Windows Update and Clear the SoftwareDistribution Folder

The SoftwareDistribution folder stores temporary Windows Update files. When these files get corrupted, updates can fail or freeze. Here’s how to fix it:

1. Press Windows + R, type services.msc, and press Enter.
2. In the Services window, find Windows Update.
3. Right-click it and choose Stop — keep the Services window open.
4. Now open File Explorer and navigate to:
   This PC → Local Disk (C:) → Windows → SoftwareDistribution
5. Select everything inside that folder and delete it.
6. Return to the Services window, right-click Windows Update, and set:
   • Startup type: Automatic
   • Click Start → Apply → OK

This clears any corrupted update files and resets Windows Update to a fresh state.

🔹 Step 2: Refresh Group Policy with gpupdate /force

Open Command Prompt as Administrator and run:

gpupdate /force

This forces Windows to refresh all Group Policy settings. It helps if your system isn’t applying update policies properly. Wait for it to show “Policy update completed successfully.”

🔹 Step 3: Reset the Catroot2 Folder

The Catroot2 folder contains crucial Windows Update components and digital signatures. If it becomes corrupted, updates may fail. Reset it with these commands. Hit Enter after each command:

net stop cryptsvc
ren C:\Windows\System32\catroot2 catroot2.old
net start cryptsvc

Explanation:

• net stop cryptsvc — Stops the Cryptographic Service
• ren ... catroot2.old — Renames the folder (Windows creates a fresh one)
• net start cryptsvc — Restarts the service

🔹 Step 4: Repair System Files with SFC (System File Checker)

Sometimes corrupted system files prevent installation. Run this command:

sfc /scannow

This scans and repairs damaged system files. Let it complete fully — it may take 10–20 minutes. Restart your PC afterward.

🔹 Step 5: Repair Windows Image with DISM

If SFC didn’t fix everything, use DISM (Deployment Image Servicing and Management) to repair Windows image corruption:

DISM /Online /Cleanup-Image /RestoreHealth

This checks your Windows image for corruption and downloads healthy files from Microsoft servers. Restart your PC when done.

🔹 Step 6: Try Updating Windows Again

After completing all steps:

1. Go to Settings → Windows Update
2. Click Check for updates

Windows should now install updates successfully without errors or interruptions.

💡 Bonus Tip

If issues persist, use Microsoft’s official Windows 11 Installation Assistant to reinstall or upgrade without losing your files.

🏁 Final Thoughts

By following these steps — stopping and resetting Windows Update, deleting the SoftwareDistribution folder, refreshing Group Policy, resetting Catroot2, and running SFC and DISM — you can safely fix most Windows 11 update or installation errors.

How to Delete, Hide, or Forget WiFi Network Name in Windows Laptop/PC (Windows 10 & 11 Guide)

If your Windows laptop keeps showing a long list of old WiFi networks you no longer use, it’s time to clean things up. Whether you want to delete, hide, or forget WiFi networks completely, Windows gives you full control — both through normal settings and using simple CMD commands. In this article, I’ll show you exactly how to do it in a clean, safe, and efficient way.

Forget or Delete a Saved WiFi Network

The easiest way to remove a saved WiFi connection is through Windows settings.

1. Go to Settings → Network & Internet → Wi-Fi → Manage Known Networks.

2. Find the WiFi name you want to remove.

3. Click Forget.

That’s it! Your PC won’t connect to that WiFi automatically anymore. But for more advanced users, the Command Prompt (CMD) method gives deeper control — especially for hiding specific or all WiFi names.

Hide or Delete a Specific WiFi Network

If you want to block a specific WiFi name from appearing in your list, use this command in Command Prompt (Admin mode):

netsh wlan add filter permission=block ssid="YOURWIFINAME" networktype=infrastructure

Just replace YOURWIFINAME with the network name (SSID). Once you hit Enter, that WiFi will disappear from your list — hidden and blocked from view.

Bring Back a Hidden WiFi Network

Changed your mind? You can easily bring that WiFi network back using this simple command:

netsh wlan delete filter permission=block ssid="YOURWIFINAME" networktype=infrastructure

This removes the block filter, and the WiFi name will reappear in your available networks. Just replace YOURWIFINAME with the network name (SSID).

Not Sure About the WiFi Name?

If you’re unsure which WiFi networks are being filtered or hidden, check them all by typing:

netsh wlan show filters

This shows every filter currently applied to your system, helping you manage and clean them up as needed.

Hide All WiFi Networks (Block Every SSID)

Want to completely hide all available WiFi networks on your computer? This is especially useful for offices, schools, or shared PCs where you don’t want users connecting to random networks. Just type:

netsh wlan add filter permission=denyall networktype=infrastructure

Now your laptop will stop showing any WiFi networks at all.

Bring Back All Hidden WiFi Networks

If you want to make all networks visible again, simply delete the restriction with this command:

netsh wlan delete filter permission=denyall networktype=infrastructure

This restores full WiFi visibility and allows your system to detect all nearby networks again.

Why Use These Commands?

Using these netsh wlan commands gives you more control over your wireless environment. They help you:

• Improve security by hiding your SSID from others.

• Clean up unnecessary or outdated WiFi names.

• Avoid confusion with multiple similar network names.

• Limit access on shared or public computers.

And the best part? You don’t need to install any third-party apps — just use Windows’ built-in tools.

Final Thoughts

Managing WiFi networks in Windows doesn’t need to be complicated. With a few simple commands, you can delete, hide, or forget WiFi network names and even block all WiFi connections if needed. Whether you’re troubleshooting, improving privacy, or just tidying up your system, these commands make it quick and effective.
