8. Mulakan Windows 10 dalam Safe Mode

You can start Windows 10 in Safe Mode to create a secure environment by turning off any services, processes and drivers that your operating system doesn’t need to work properly. Then, you can try to run Windows Update in Safe Mode to see if it works. Here’s what you need to do:

1. Right-click the Start button and select Settings
2. Click Update & Security
3. Jump to the Recovery section
4. At Advanced startup, click Restart now
5. Windows will boot in troubleshooting mode. Go to Troubleshoot > Advanced options > Startup Settings
6. Click Restart
7. Press F5 to enable Safe Mode with networking
8. After the OS starts, try to run Windows Update
9. If the update is successful, restart your PC as normal to exit Safe Mode

9. Run a clean boot

It’s possible that Windows Update is hampered not only by services, processes and drivers, but also by startup applications. For example, it could happen if you have a third-party antivirus solution that’s scheduled to run every time you turn on your computer. But you can run a clean Windows 10 boot:

1. Press Win key + R, type msconfig, and hit Enter to open the System Configuration app
2. In the General tab, choose Selective startup
3. Disable Load system services and Load startup items
4. Click Apply and exit
5. Press Ctrl + Shift + Esc to open Task Manager
6. Switch to the Startup tab
7. Disable all programs with the Enabled status
8. Restart your computer
9. Try to run Windows Update
10. If it works, restart your PC after the updates

10. Restore firewall settings to default

If you have tinkered with the Windows Defender Firewall settings, you might have unknowingly restricted the Internet access of critical files that Windows 10 needs in order to perform updates. It can be challenging to undo one setting at a time, but a simpler solution is to restore everything to default. Here’s how:

1. Click the Start button, type Windows Security, and open this app
2. Select Firewall & network protection
3. Scroll down to the bottom of the window and click Restore firewalls to default
4. Click Restore defaults and Yes to confirm
5. Try downloading system updates now

11. Uninstall system updates

It might sound absurd that a system update released by Microsoft could corrupt the very feature used by Windows 10 to check for updates. But it can happen since many system updates are unpredictable. Thankfully, you can resolve this matter by removing the most recent Windows update from your PC.

1. Press Windows key + R, type appwiz.cpl, and hit Enter
2. Click View installed updates on the left side
3. Click the Installed On column to sort the updates (newest first)
4. In the Microsoft Windows group, double-click the first update
5. Click Yes to confirm and follow any further instructions
6. Restart your PC and check for updates
7. If it works, make sure to not download the same update again

12. Fix hard disk errors

If your HDD or SSD has corrupt files or bad sectors, this could cause Windows Update functionality problems, leading to error code 0x800705b4. However, you can resort to CHKDSK (Check Disk) for help.

How to use CHKDSK:

1. Press Win key + R, type cmd, and press Ctrl + Shift + Enter to run Command Prompt with elevation rights (click Yes if asked by User Account Control to confirm)
2. If Windows is installed on the default C: partition, run chkdsk c: /f /r. Else, make sure to use the correct drive letter instead of c:
3. When you’re asked to schedule the checkup at the next system startup, type y and press Enter
4. Restart your computer. CHKDSK will check the disk and fix any errors

13. Repair corrupt system files

If CHKDSK doesn’t work, it’s likely because your operating system has corrupt files, which you can resolve with the help of SFC (System File Checker).

How to use SFC:

1. Click the Start button, search for Command Prompt, and click Run as administrator
2. Run sfc /scannow and wait until SFC does its job
3. Restart your PC and try Windows Update

If SFC doesn’t show any problems, you can use DISM to check the component store of the OS image.

How to use DISM:

1. Launch an elevated instance of Command Prompt
2. Run DISM /online /cleanup-image /scanhealth
3. If DISM finds any problems, fix them by entering DISM /online /cleanup-image /restorehealth
4. After DISM finishes its job, restart your PC
5. Relaunch Command Prompt as admin
6. Run sfc /scannow and wait
7. Restart your PC one last time and try Windows Update now

14. Check your PC for malware

It’s a good idea to run a virus scan on your PC and remove any malicious threats using Windows Defender:

1. Press the Windows key, search for Windows Security, and hit Enter
2. Select Virus & threat protection
3. Click Scan options
4. Choose Quick scan and click Scan now
5. If the scan results don’t show anything suspicious, run a new scan after selecting Windows Defender Offline scan mode
6. Allow Defender to quarantine or remove any infected files. If you think some of the alerts are false positives, make sure to add those files to a whitelist in order to exclude them from further scans
7. Reboot your computer
8. Check if you can use Windows Update now

15. Run Windows Update Diagnostic

Published by Microsoft, Windows Update Diagnostic is a tool you can download and consult to find and repair additional Windows Update problems that aren’t already covered by the integrated Windows Update troubleshooter. Here’s how you can use it:

1. Log in to Windows 10 using an administrator account
2. Download Windows Update Diagnostic from the official website
3. Fire up the application
4. Pick Windows Update and click Next. Follow the given instructions
5. Once the wizard completes, restart the app
6. Select Windows Network Diagnostics and click Next
7. Restart your PC and try to download system updates

16. Verify Group Policy settings

Windows Update needs Group Policy options to be configured in a certain way. Otherwise, you can wake up with errors like 0x800705b4 when trying to download and install system updates. Here’s what you need to do in this case:

1. Press Win key + R, type gpedit.msc, and press Enter
2. In Local Group Policy Editor, visit Computer Configuration > Administrative Templates > Windows Components > Windows Update
3. Right-click Configure Automatic Updates and select Properties
4. Choose Enabled and click Apply
5. Restart your computer

17. Remove external devices

If you started getting Windows Update errors after attaching a new piece of hardware to your computer, that might be the culprit. Some devices don’t fully support Windows 10 computers, even those with plug-and-play features. So you can expect system stability problems because of this, even a failure to check for system updates.

To test this theory and fix the problem at the same time, just unplug any new devices you attached to your PC lately, like a USB flash drive, a webcam adapter, or a Wi-Fi dongle. Then, restart your computer and try to run Windows Update.

18. Check the disk space

Insufficient disk space can lead to all sorts of computer problems because Windows doesn’t have enough room to download files and run processes. You should check the Windows 10 notifications center for any messages concerning low disk space. In this case, you can use a partition manager like Disk Management to increase the Windows drive capacity.

How to use Disk Management:

1. Click the Start button, type Disk Management, and open this app
2. Pick a big partition that doesn’t contain Windows
3. Right-click this drive and select Shrink Volume
4. Specify the new volume size by removing a considerable amount (at least 1GB) and click Shrink
5. Shift your attention to the Windows partition. Right-click the drive and select Extend volume
6. Set the volume size by adding all the available disk space. Click Extend
7. Restart your computer

An alternative solution is to remove existing files from the Windows drive, in order to make room for system updates. Try moving files to other partitions or even a removable storage device. Furthermore, you can uninstall large and unused applications and games, upload important files to a storage account, or burn DVDs.

If you still don’t have enough disk space on the Windows drive after going through all this trouble, use a system cleaner like Disk Cleanup to get rid of all junk data that unnecessarily occupies your disk space.

How to use Disk Cleanup:

1. Before getting started, visit Downloads and Recycle Bin. Make sure to save or restore any files you might need later since these folders will be cleared
2. Click the Start button, search for Control Panel, and open this app
3. Click Administrative Tools
4. Open the Disk Cleanup utility
5. Select the C: drive or where you have Windows installed
6. At Files to delete, select everything and click Clean up system files
7. Once the file scan is over, pick all items again and press OK
8. Reboot your machine

19. Fix registry settings

Windows Update error 0x800705b4 could be caused by incorrect registry settings, where a registry cleaner can’t help. Here’s how you can fix them:

2. Open the File menu and click Export
3. Set a name and destination to save a registry backup file

• Run an Internet speed test

21. Use System Restore

If you can’t find the source of the problem, consider rolling back Windows 10 to a restore point that was recorded before you started experiencing Windows Update issues. However, it means that all applications installed after the restore point was taken will no longer exist on your PC, so you will have to reinstall them.

How to roll back Windows 10:

1. Press the Win key, type Control Panel, and launch this app

How to reset Windows 10:

1. Right-click the Windows 10 Start button and go to Settings
2. Select Update & Security > Recovery
