If you’re having issues where you’re not able to download any updates including Windows Defender’s using Windows Update in Windows 10 and receiving “we couldn’t connect to update service’ you’re not alone, the issue seems to be with Microsoft servers and the outage.servers. also confirms the issue exists for users in some countries. While we’re able to download app updates from Microsoft Store (this issue is also reported by users) but noticed Windows Update section without the check for updates button for the first time, here is the workaround that worked for us and for you to fix updates issues you’re having.
1. Right click on Network icon in the Notification area
2. Open Network & Internet Settings
3. Click change adapter options
4. Right click on Network Adapter, select Properties
5. Select Internet Protocol version 4 (TCP/IP4), properties
6. And assign following Google DNS server addresses after selecting ‘Use the following DNS Server addresses”
See if the issue gets resolved on your end, this worked for us, try this if Windows Update is having trouble downloading updates also, expect issues with Windows Activation also.
Generally, if you’ve issues with Windows Update, you should be running Windows Update troubleshooter, since the issue is on Microsoft servers end or could be related to your DNS, running troubleshooter may not help, but workaround mentioned above should work.
Some of the affected users who’re not able to download Windows Update Defender definitions or download apps from Microsoft Store posted on Reddit here and here and still contacting @MicrosfotHelps on Twitter for support on this issue.
The following tweet summarizes the issue users are facing right now at different parts of the world.
That’s a useless link MS. You have major issues with the update servers. Widespread issues with defender definitions getting stuck downloading and store apps being affected. Why do you carry on like it’s the first you’ve heard of it? I have already tweeted this over 24 hours ago
