Note:

1. Windows Server 2012 and Windows Server 2016 take up more memory. Installing other applications makes memory consumption higher, which may lead to installation failure due to insufficient memory. Therefore, it is recommended to increase physical memory. If it is an IO optimized instance, you can turn on system virtual memory as appropriate.

two。 If the installation error: 0x800f081f, then check whether the public network is normal. If so, the update failure may be caused by an unstable link to Microsoft update server. It is recommended to try again during the replacement period.
