Last week, multiple Windows 10 users complained that they were unable to gain access to the Windows Update service and also failed to download anything from the Microsoft Store. The software giant immediately launched an investigation into the issue after acknowledging the problem, but without giving any explanation about its cause at the time.
Now, Microsoft has confirmed that the service-side issue has been fixed and the company also shed more light on the bug that prevented some users from connecting to Windows Update. The company said via the Windows Support page:
“The Windows Update service was impacted by a data corruption issue in an external DNS service provider global outage on January 29, 2019. The issue was resolved on the same day and Windows Update is now operating normally, but a few customers have continued to report issues connecting to the Windows Update service. We expect these issues will go away as downstream DNS servers are updated with the corrected Windows Update DNS entries.”
There was no mention of a fix for the Microsoft Store-related issue, however. Although Microsoft didn't go into detail, the issue might have been related to Comcast's service, as claimed by a Windows 10 user.
The issue surfaced a few days after an older version of a particular Windows update was trying to make its way to Windows 10 PCs again following its release in December 2018. That eventually resulted in an installation error due to duplicate copies of the update.
