How To Fix Error 0x800704cf In Windows 10?

Reader Question:
“Hi Wally, Since I’ve upgraded my computer to Windows 10, its been working fine I have some problems though, Teamspeak isn’t working since the upgrade, and I can’t get hotmail and outlook synced with each other. It gives me this error: 0x800704cf.” – Michelle T., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: Windows 10 has seen an amazing adoption rate. Microsoft’s statistics show that activations reached the 75 Million mark after a month of its public release. No software is perfect though, and Windows is different. Here we will look at how to fix Error 0x800704cf.


Can’t sync Hotmail and outlook in Windows 10 due to error 0x800704cf. People have seen this problem when trying to use their Hotmail client with Windows 10.


Here are some ways to fix the 0x800704cf error:

Use The SFC Scan

SFC is used to fix corrupt system files. Missing system files can also be replaced automatically through this command.

  1. Press the Windows Key > type cmd to search for the Command Prompt.
  2. Right-click Command Prompt > Click Run as administrator
  3. In the Command Prompt window, type sfc /scannow > Press Enter to run the command.
    Windows 10 Start Menu - sfc scannow - 2 -- Windows Wally

Use The Device Manager To Fix The Problem

This is a network driver related problem, so we need to solve it from the network driver. Here’s how you’d do it:

  1. Press the Windows Key + X > click Device Manager
    0x800704cf - Windows Key + X - Device Manager -- Windows Wally
  2. Expand the Network Adapter category
    0x800704cf - Device manager - Expand - Network adapter -- Windows Wally
  3. Press Alt+V to open the View menu.
  4. Click Show hidden devices
    0x800704cf - Device manager - Show hidden devices -- Windows Wally
  5. Right-click and Uninstall each device under the Network category one-by-one. Some of them won’t get Uninstalled, don’t try to uninstall them.
    0x800704cf - Device manager - Show hidden devices - Uninstall -- Windows Wally
  6. After doing this, right-click the remaining devices in the Network category, and click Scan for hardware changes. Do this for all remaining devices.

This should uninstall corrupt drivers and install stable versions of them, ready for use.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
