what is runtime broker, and why does it use so much memory?

I've also posted about this before.   The only way I could eventually definitely stop Runtime Broker 'taking over' was to end the process each time the computer was turned on but this was a pain to do each time.  But I just got into the habit of doing it.

But since a week or two ago, after a very significant update of Windows 10, the problem really does seem to have finally been sorted.  I haven't knowingly changed anything but Runtime broker now never uses any significant amount of RAM or processing power.   I thought I should post this in case you want to try again with Windows 10!

I've posted about this a few times.

I eventually 'fixed' the problem with using a different windows image and turning most everything off.

I had several weeks of trouble free computing. Then MS decided we needed an update that restored Runtime to its former glory. And back I went to 100% CPU usage.

I considered my options and wondered what the point was of having Win 10 if much of it has to be disabled.

I have now gone back to Win 7.

For the information of others I had tried each of the fixes and none worked. In the end I disabled RTB and all the live tiles.

I have/had no significant 3rd party software. I do have a NAS server.

Norton has been a memory problem for years - I have now given it up completely.  The problem does usually come from badly written programs that runtime broker is trying to work with.  I have a number of options I use (Iobit, panda, glary utilities etc) to handle my security as well as secure routers between my modem and my computers.  I regularly check Task Manager if things slow down to see what is hogging too much memory and I uninstall anything that uses too much.  There are many better options than Norton (check CNET and ZDNET for their reviews of the latest offerings - their efficacy changes from year to year) and be prepared to change your security preferences.  Also try the iobit uninstaller as it is very good at finding all the **** that the high level progs leave behind and which sit in the registry clogging up the running of Windows 10 (and 8).

So start with a secure router and only add what is needed to keep yourself safe. Monitor your spam file to see what is getting through and don't add more security than you need.  And don't open messages that come from unknown sources.  Also chrome and gmail are very good at spotting and blocking nasties.  One other tip - before you click on a link, mouse over it.  In Chrome, you can see the real URL that the link will take you too - if it looks suspect it almost certainly is.  Common sense always helps.
