Here is the NSI process after 2 days UP TIME.
I have Windows Update set to NOTIFY ME when updates are available, NOT DOWNLOAD and NOTIFY, or DOWNLOAD and INSTALL. This way I can assure my system does not reboot while trying to monitor this. Also, this was AFTER installing MS Office, and all it's updates through Windows Update.
Feel like I am chasing a ghost at this point. My memory usage is minimal, goes up during updates, but settles back around 1.4GB of 8GB available at idle. NO strange spikes, no strange processes draining anything. Granted, this is a whole new computer, SAME OS, and SAME network connection.
All I can say to those affected... As much as it sucks... TRY a fresh install. That is what I am on with this new build, and no issues so far. Granted, like others, the problem may pop up after 16 days of up time, I will monitor and let you all know. Still have IE 9 active, IE 10 and IE 11 HIDDEN from the update list. ONCE I get 16 days CLEAN, I will update to IE 11.
Good luck guys!
