Windows 10 Start menu search is not working

I had the annoying issue that my Windows 10 Search bar stops working for some reason. Trying to restart the services, restart Windows and kill the Cortana processes doesn’t work in my situation. After a lot of searching, I’ve found the solution in some forum.

Invoke-WebRequest : The response content cannot be parsed because the Internet Explorer engine is not available

Yesterday I was facing this error when running a SMA Runbook with the invoke-webrequest cmdlet. For troubleshooting I had to enable SMA script logging for this runbook so I was able to see wats going wrong. The error says you must run the “getting started setup” of internet explorer for the service account which is running the scripts.

 

This is not ideally when you run this script on multiple servers. Now there are 2 options available to ignore this stupid error:

1. Enable the Group policy object (GPO) for Prevent running first run wizard. This setting is in “Computer configuration -> Policies -> Administrative templates -> Windows Components -> Internet Explorer”. Set the “Prevent running first run wizard” to enabled.

2. Run the Invoke-webrequest with the –UseBasicParsing CMDlet.

MSMQ errors in ClusterLog

What is MSMQ:

You can use MSMQ for Application communication across heterogeneous networks and systems that may be temporarily offline. Applications send messages to queues and read messages from queues. A queue is a temporary storage location from which messages can be sent and received reliably, as and when conditions permit. This enables communication across networks and between computers, running Windows, which may not always be connected.

When MSMQ is not enabled or not configured you get a lots of errors in your Windows Cluster log.
In our Hyper-v cluster we don’t need MSMQ.

Errors we faced:

ERR   [RHS] s_RhsRpcCreateResType: (21)’ because of ‘Startup routine for ResType MSMQTriggers returned 21.’
INFO  [RCM] result of first load attempt for type MSMQTriggers: 21
WARN  [RCM] Failed to load restype ‘MSMQTriggers’: error 21.
