    I was trying to get permission from Trustedinstaller but, in retaliation, I passed the permissions to the SYSTEM entity, but looks like I can't log into it as quoted inthis topic. Now, what should I do? Thanks in advance.

    :)

    Put processes that consume a lot of resource on the top of the list in Task Mananger

    A main use of Task Manager is to find which program is consuming resources. Now we need to sort by CPU/sort by Disk/sort By network to find the problem. Its better if list all the huge resource consuming programs at the top of the list what ever the resource
    is so we don't need to sort in most cases.

    How can I stop MsMpEng.exe from consuming my computer resources once and for all?

    MsMpEng extreme and almost constant disk usage after Windows update (aprox.2016-08-03)

    MsMpEng and System constantly (mostly) reads disk at high rate. The problem has started couple of days ago. The only thing that was installed during that time was windows update (ok and Adobe and Steam updates).

    After some time the disk activity will stop, however it will resume sometime latter.
    And no, I had not installed any third party security applications.

    In resource monitor it can be seen that Diks activity is 2-8 mb/sec and process name is either System or MsMpEng .

    Sometimes there are significant pagefile usage (computer has 4gb) and nothing is currently running (like now I am running only Internet Explorer with this Microsoft page and my Windows are using pagefile like there is no tomorow) . When pagefile usage creeps
    up then all kinds of processes are using the pagefile. However resource monitor memory tab shows bigest process beeing MsMpEng with 644kb (note again it should not cause 4gb system to run out of memory). Right now system is writing 2mb/sec (read 0.4kb/sec) to
    pagefile and MsMpEng is reading 2mb/sec from pagefile.

    And no, running said Windows defender does not show up any viruses.

    Basicaly - this is rant about apparently bugy latest Windows update.
