Windows Reliability Monitor errors

skcusime · 23 Jul 2017

Windows 10 64 bit , 15063.483, Office 365, Malwarebytes pro all up to date.
I have daily errors of "Microsoft Windows Search Protocol Host" or "SearchProtocolHost.exe" stopped working.
The only changes major changes in the past month is the migration from Office 2007 to Office 365, but that was a month ago and this daily problem only started about 14 days ago. Nothing actually effects the working of the computer, and there are no signs anything has stopped working - it just shows up in the reliability monitor.
Any clues what may be causing this issue?
I've done full Windows Defender scans, full Malwarebytes scans, and the system is up to date.
SFC /scannow shows no errors.

Hi, this can happen if there's a failure to access or index a file.

In particular, problems have been reported a number of times with respect to Outlook files.
Example: this very old thread:
Windows Search Protocol Host Has Stopped Working [vista]

You can also try this basic check in case sthg has happened to your file system:

From an admin command prompt
[Windows key + X, click command prompt (admin)]
chkdsk C: /F
Your PC will need to restart.
Post back the result, which you can get after a restart as follows:

Make sure the result is clear or fixed.

If you have a red flag and if your only option given is :check for a solution",then put your cursor on it BUT RIGHT CLICK ONLY.This will bring up another option"view tech details",left click on it and a data page will appear.
The line entitled Bucket id will give you the information for a search to see if a solution exists.

Also see the first report here:
OUTLOOK 2016 SEARCHPROTOCOLHOST.EXE STOPPED WORKING - Microsoft Community

Do you see any similar excessive CPU use?

Whilst you can try rebuilding your search index, it is quite probable that will not solve this issue- worth trying anyway.

Thanks for your replies.
Results of chkdsk here. Nothing strikes me as anything outstanding.
