windows defender slow start-up

[boden08]

Hi all,
I have been having some huge issues with windows 10 regarding to the system start up and opening up other application.

The issue started after the new Threshold 2 build ( 10586.29). previous to this build the operating system was running perfect and didn't have a single complaint.

The problem starts the moment windows starts to load up, just very slow then seems to hang for a short period then the desktop shows and nothing is loaded on the desktop. Each icon then loads slowly including the task bar and in total could take up to 2-3 minuets where as previously would take a maximum of 30 seconds for everything to be loaded.

This problem then continues on with other applications, for example just loading up Google could take up to 30 seconds if not more where as before it was instant.

I have Google this problem and tried to solve the problem through the various fixes with the slow start up problem but most was related to first build of windows 10 or regarding to a certain application like Skype.

When first booting up the operating system i open up task manager and find the anti malware services (windows defender) causing my hdd to be running at 100%. so i run another test and turn off defender and again do another reboot. system starts up perfect no problems and takes around the normal 30 seconds to boot up with everything loaded.

so I now know it is windows defender causing the system to be so slow but would like to continue to use defender as i have not had a single attack since using it at the start of windows 8, other antivirus has failed me in the past and i tend to stick to what i know and works.

so does anyone know of any information regarding to this problem or any suggestions it would be greatly appreciated.

if any other information is needed just ask.

thank m boden

I'm assuming you're not using a real AV program, Win Def finishes at the bottom (by a large margin) of every AV test site anywhere in the world.

That said, I suspect that Win Def is doing a system scan at start up.

Go to win def in the Control Panel run through the options and uncheck everything except Scheduled Scans.

Go to task Manager, Startup and uncheck everything. If you had a real AV program, you would leave that checked, as it does a Root check on start up.

thanks for the reply fallon,
I have tested quite a few av programs including avast and f secure both do the same. since my post I have done a complete fresh install of windows 10, with just the os on the disk the hdd usage is still the same even with no av enabled. I'm assume my disk is on the way out.

I have tried two different defrag software's and once the defrag is complete and says 0% fragmentation I run another analyst of the hdd and again the fragmentation is back to 13%.
