Windows 10: Memory usage remains at 50% after the standard fixes on Windows 10

I have tried the suto fresh startup, ran malware software, did not defrag but it says fragmentation is at 0%. Also deleted the index on control panel and did a reindex. Memory usage remains at 50% right after startup. CPU time and Network for apps is very low across the board. This computer has 12g of Ram. Could bad ram be the problem? Suggestions?

:)

 

Memory at 50% and Disk usage at 100%

So I bought a brand new gaming laptop and it came with Windows 8 and so I used that for the first day or two and there were no problems. I installed Windows 10 and now the ram/disk was both at 100% most of the time. I was able to fix some mem leak though
the memory is ALWAYS at 50% now and the disk usage is at 100% for the first 30 minutes after start-up. How can I fix these problems?

 

memory usage stuck over 50%

so for a while (maybe 2 to 3 year never cause me any problem until recently) the memory usage of my computer have ben stuck over 50% even when idle

i have 8 gb of memory and my usage is allway around 4.0 to 5.0

before i was just thinking that it my computer that is weak or was having not enough memory

 

System and compressed memory high disk usage during file copy

Thank you Amarjeet_Paul.

I spent many more hours than I had hoped this past week reading and trying others' suggestions from this community on how to reduce high RAM usage due to ntoskrnl.exe. The "System and compressed memory" process remained the top consumer of RAM, using 500-900MB,
among all other processes running. I deemed it to be the likely culprit in making my computer use frustratingly sluggish. After completing your
third step, steps 1. & 2. provided no improvement in my case, the "System and compressed memory" process RAM usage has plummeted from the top of the Task Manager Process list to the bottom, running at a remarkable 0.1MB! That's a whole lot less than
1% of the targeted process' gluttony. You're hired! Ps. I'll be keeping an eye on the process' use as I get back to normal operations, and be back if it floats to high in the list. Or if the registry fix you suggested has compromised use in any way. Please
explain in simple terms what the insertion of your registry modification is doing.

Thanks again.
