Method 2: Clear the Windows Update Cache (Advanced Fix)

Difficulty Level: Intermediate | Success Rate: 75-80% | Time Required: 15-20 minutes

Windows Update stores temporary files in a folder called SoftwareDistribution. If these files become corrupted, the update process fails. This method resets those files.

Prerequisites

Administrator account access
Backup important files (optional but recommended)

Step-by-Step Instructions

Step 1: Open Command Prompt as Administrator

Click the Windows Start button
Type command prompt in the search box
Right-click Command Prompt
Select Run as administrator
Click Yes when prompted by User Account Control

Step 2: Stop Windows Update Services

Type the following commands one at a time, pressing Enter after each. Wait for each command to complete before typing the next:

textnet stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver

What These Commands Do:

wuauserv – Windows Update service
cryptSvc – Cryptographic service (required for update verification)
bits – Background Intelligent Transfer Service (downloads updates)
msiserver – Windows Installer service

Step 3: Rename the SoftwareDistribution Folder

Type these commands (including spaces exactly as shown):

textren %systemroot%\softwaredistribution softwaredistribution.bak
ren %systemroot%\system32\catroot2 catroot2.bak

Why Renaming Works: Windows automatically recreates these folders when services restart. By renaming rather than deleting, you preserve the old files as a backup in case you need to restore them.

Step 4: Restart Windows Update Services

textnet start wuauserv
net start cryptSvc
net start bits
net start msiserver

Step 5: Close Command Prompt and Restart

Type exit and press Enter to close Command Prompt
Click the Windows Start button
Click the Power icon
Select Restart
Allow your computer to fully restart (this may take 2-3 minutes)

Step 6: Check for Updates

After restart, go to Settings > System > Windows Update
Click Check for updates
Download and install any available updates

Troubleshooting This Method

Problem	Solution
“Access Denied” error	Ensure you’re running Command Prompt as administrator. Some antivirus software may block folder operations—temporarily disable it.
Folders won’t rename	Restart your computer in Safe Mode and attempt the rename again.
Services won’t stop	Check if other programs are using update services. Close all applications except Command Prompt.

Method 3: Repair Windows System Files Using SFC (Deep Repair)

Difficulty Level: Intermediate | Success Rate: 60-65% | Time Required: 30-45 minutes

You’ll see a progress bar showing “Scanning”
This process can take 15-30 minutes depending on your hard drive speed
Do not close the Command Prompt window until the scan completes
You may see messages like “Scanning system files” and “Repairing files”

Step 3: Review the Results

Once complete, you’ll see one of these messages:

“The operation completed successfully” – Corrupted files were found and repaired. Proceed to Step 4.
“Windows Resource Protection could not perform the requested operation” – Try running the command again or restart in Safe Mode and retry.
“Windows Resource Protection did not find any integrity violations” – No corrupted files detected. Proceed to Method 4.

Step 4: Restart Your Computer

Type exit and press Enter
Restart your computer through Start > Power > Restart

Step 5: Check for Updates Again
