I have a HP pavilion laptop running windows 8.1 and office 2013.
Things have been fine from Feb to until Nov this year, after which point I noticed the mouse cursor showing the busy revolving circle all the time, performance was reduced and the computer sounded like it was constantly working.
I traced the problem to the Microsoft office Click-to-run process running with high CPU (5+%) and memory (50+mb). If I restarted the click-to-run service the use of computer resources dropped to minimal and the problems described in the first paragraph disappeared.
Unfortunately as time has gone on an error occurs when trying to stop the click-to-run process so the above restart fix does not work and the longer the laptop is on the worse the performance gets.
I have reinstalled office twice, I hace clicked the office repair option and searched the web for a solution all to no avail.
Please can somebody help find a solution as it is driving me mad and making my new laptop unusable. BTW my partner has a similar laptop setup with no issues.
