What should I do if Win10 Preview 14946 fails to upgrade? Some anti-virus software led to win10 can not be upgraded solution

Although several recent Windows 10 Preview versions have brought us a lot of new features worthy of attention, but small problems are still there. For the Windows 10 Preview Build 14946 version that Microsoft just released, some anti-virus software is not working properly. Let's take a look at the details below!

However, it is not a big problem to use these anti-virus software normally, but if you have installed security software such as Kaspersky, there may be some problems that may cause the upgrade if it is updated to this version.

Microsoft mentioned in the blog:

If you have anti-virus software such as Bitdefender, Kaspersky Antivirus, F-Secure Antivirus or Malwarebytes installed on your device.

There may be an error when you upgrade to this version, causing it to fail to install properly, and the system will automatically roll back to the previous version.

So in order to avoid unnecessary trouble, I suggest you uninstall these anti-virus software and try to upgrade to the latest Windows 10 beta.

Of course, if you are used to using these anti-virus software, you can also not update, waiting for Microsoft to release the next test version.

It's interesting to note that Kaspersky also posted a blog yesterday saying that there are still some problems that prevent some of Kaspersky's features from being used on Windows 10 (official version).

There are still compatibility issues with the official version of Windows 10, so the beta version can't be used normally, but it's normal, so keep waiting.
