Memory leak (usage gradually increases)

Ever since I upgraded to Windows 10, I have noticed something. The memory usage gradually increases over time (starts off just under 30%, takes only a few days to climb to 50%, depending on how many programs I use) and I inevitably have to reboot, after which the whole cycle starts over again. All I know is that something in the background is gradually eating away at the memory and I have been unable to track down what it is. I looked in the Resource Manager once and found that the processes using the largest amounts of memory were OSDSrv.exe, the webcam which I don't know how to turn off, MsMpEng.exe (the Windows Defender process), and SearchUI.exe which is just Cortana sitting idle in the background. Can anyone help me? Also the non-paged pool of memory is larger than the paged pool of memory but they are within 100MB of each other.

When I said the memory usage I meant to say the memory usage without anything open.

I would check in Task Manager -> Startup tab, and disable all unnecessary applications. See if the Webcam software is in that list.

Regarding Paged and Non-Paged pool sizes, how large are they? If you do have a pool leak you'll want to use PoolMonX, and sort by KBytes from highest to lowest. Monitor it over the course of several hours or day (feel free to post screenshots) and see if any "Tag" (left most column) is taking up an ever increasing amount of KBytes.

Don't forget if you're using Windows Metro Apps a lot, disable their background tasks on settings to prevent apps from caching to memory when they're not being used.

The apps I use often are Chrome, MS Paint, MS Word, Minecraft, MCEdit (the world editor for Minecraft), and my recording software. Also I do not find anything in task manager when the memory usage without anything open is high and the things using the most memory are usually the Antimalware Service Executable and Service Host: Local System (Network Restricted). Also I would disable the webcam but only problem is I do minecraft youtube videos and I think that would turn the mic off.

How much memory do you have? Windows will use RAM to anticipate programs that you use often to speed up the program's startup. This is normal.

How high does the RAM use go?

Also, it is better if you include the details of your system under the system specs. This makes it easier for people to assist you.

I have 6 gigabytes of RAM. I usually reboot when the usage with nothing open is around 50% but I am just doing what I inevitably have to do because one time it climbed all the way up to 67% and in fact I think it would just keep climbing.

Hey allam447635,
That OSDSrv appears to be for a dell wireless keyboard caps lock indicator. Check for it Task Manager > Startup for IndicatorOSD and disable it. Also check Windows Services for 'ChiconyOSDService' (OSDSvc) and set the Startup Type to Manual.

For your web cam check Windows Services for web cam name/software and set Startup Type to Manual. It might also be in Task Scheduler with multiple triggers defined and one of them is probably run at user login, so you could disable it.

I do not see OSD Service Application in the startup menu. Also I am sure that that is not what is causing the gradual increase in the RAM usage.

Post a screenshot of Task Manager - Performance tab showing memory info when the problem occurs. Otherwise this is all just guesswork.
