- Right-click Start and run Command Prompt (Admin).
- In the command line type
netsh winhttp show proxy
- In case you are prompted with Direct Access (no proxy server) message, everything is safe and sound.
To disable your proxy, do the following:
- Press Windows Key + I to open the Settings app.
- Now navigate to the Network & Internet section.
- From the menu on the left, select Proxy. In the right pane disable all options.
After doing that, your proxy should be disabled and the update error 0x80242ff should be resolved. If you still want to protect your privacy online, we strongly suggest that you consider using a VPN instead of a proxy.
There are many great VPN services available, and one of the best is Private Internet Access (PIA), so be sure to try it out.
3. Check the integrity of your system files
- Press Windows Key + X and select Command Prompt (Admin) from the list (or PowerShell for older systems).
- Enter sfc /scannow and press Enter.
- The SFC scan will now start. The scanning process can take about 15 minutes, so don’t interrupt it.
This process finds and fixes corrupt files, if any. Once the SFC scan is finished, check if the problem is still there.
If it is, you need to run a DISM scan. You can do that by following these steps:
- Open Command Prompt as administrator.
- Now run the following command and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth
- Once again, the scanning should take about 20 minutes, so don’t interfere with it.
After the DISM scan finishes, check if the problem is resolved. If you want, you can also repeat the SFC scan once again and check if that solves the problem.
4. Start system in Clean Boot
- Press Windows Key +R, enter msconfig and press Enter.
- Go to the Services tab and check Hide all Microsoft services box.
- Then click Disable All and confirm with Apply.
- Go to the Startup tab and choose Open Task Manager.
- Disable all startup programs individually and press OK.
- Restart your PC and try updating.
5. Reset Windows Update services
- Start Command Prompt as administrator.
- Disable your network connection.
- Now run the following commands one by one:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
After running these commands enable your Internet connection once again and restart your PC. Once your PC restarts, check if the problem is resolved.
6. Turn off the Windows Firewall
- Press Windows Key + S and type firewall.
- Choose Windows Defender Firewall from the list.
- Select Turn Windows Defender Firewall on or off.
- Select Turn off Windows Defender Firewall (not recommended) for both Private and Public networks.
- After doing that, click the OK to save changes.
Once you disable Windows Firewall, check if the problem is still there. If the issue is resolved, update Windows and then turn the firewall back on again.
7. Download the update from the Microsoft Update Catalog
If you can’t download a specific update due to update error 0x80242ff, you might be able to fix that problem by downloading the update directly from Microsoft’s online Update Catalog.
Before you can do that, go to the Windows Update section on your device and look for the update code of the update you’re trying to install.
The update will contain KB plus an array of numbers. Once you find the update code, do the following:
- Go to the Microsoft Update Catalog website and enter the update code in the search box.
- Pick the update that uses the same architecture as your PC and click the Download button.
- Once the download is finished, double-click the setup file to run the installation.
After the update is installed, your Windows will be updated to the latest version.
Keep in mind that this method might not fix the core problem, but it will allow you to circumvent the error message and install the update.
8. Perform an in-place upgrade
- Download and run the Media Creation Tool.
- Choose Upgrade this PC now.
- Wait while the setup prepares the necessary files.
- Choose Download and install updates (recommended)option.
- Now click the Next button.
- The setup will now download the updates. This might take a bit, so be patient.
- After the updates are downloaded, follow the instructions on the screen.
- Once you reach the Ready to install screen, click Change what to keep.
- Select Keep personal files and apps and click Next.
- Follow the instructions to complete the setup.
Once you complete the in-place upgrade, you’ll have a fresh up-to-date version of Windows. Of course, all your files and applications will be preserved, so you can continue where you left off.
These were possible workarounds for this update problem. We certainly hope you’ll find it useful and manage to resolve the 0x80242ff error in no time.
