Issue: How to fix SAFE_OS phase error during REPLICATE_OC operation in Windows 10?

Hi, I have been trying to update Windows for more than six months now, to no avail. Whenever I try, I always receive an error code 0x8007001F – 0x20006 “The installation failed in the SAFE_OS phase with an error during REPLICATE_OC operation.” It would be great if you could provide some solutions to this. Thanks.

Solved Answer

Microsoft operates Windows as a service, which means that users can expect to get constant updates. Usually, these updates are shipped every second Tuesday of every month; they improve stability and performance, fix bugs, improve UI[1] elements, add new features, and patch security vulnerabilities.

However, every six months or so (this might vary in some cases), Microsoft releases a new version, which includes much bigger changes. Since the release of Windows 10 back in 2015, there have been 12 upgrades provided.[2] At the time of the writing, the newest update version is 21H1.

Not all users are able to proceed with implementing the newest Windows version, however. Some users reported that they could not upgrade the operating system for months or even years, thanks to the errors that occur during this process.

“The installation failed in the SAFE_OS phase with an error during REPLICATE_OC operation” is just one of many errors that might prevent users from installing the newest updates or newest Windows version. The error message is also typically accompanied by an error code 0x8007001F – 0x2000.

In most cases, the reason for this error to show up during the Windows update is incorrect settings to certain OS components. Disabled services might also be a major contributor. In some cases, updating your drivers[3] might help you solve the issue.

Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speeds.
