    "registry" process permanently writes to disk


    I noticed for some time, that I have a process called "Registry" in Task Manager which randomly uses 0.1-1% CPU usage. I dont have this process running on my Desktop or tablet, just my laptop.
    I opened MS Process Monitor, filtered the name and disk usage and this showed up:

    It seems to write all the time some log entries.

    Anyone know, why this is, and why I just have this behavior on my laptop and not my other Windows 10 devices?

    That was not an answer to my question. Why is it writing all the time log files on my laptop and my other devices not.

    The purpose of the Registry process is to optimize performance and memory usage of the registry. The details of how all this works have not been documented and probably won't be. There is much about Windows that has not been documented outside Microsoft. The same is true for other operating systems.

    You need to look at what else is running on your system that is causing the registry process to be this active.
    I see 0 activity on my system as a rule.

    That is why I am asking here... it seems that Registry, but also System are writing all the time 24/7 with 0.1MB/s to disk

    And I am worried about my SSD life time.

    There is nothing really running on the laptop, it also has 16GB of RAM. The laptop is about 6 months old but the SSD already has 5.6TB of bytes written to it, which I dont really know where this is coming from, it seems a lot to me for that time.

    Well, my Samsung 860 EVO 500GB SSD is 2.5 months old and has 16.5TB of data written to it. I have not taken, nor will I take any special precautions to protect the drive. I use it just as I would a normal HDD.

    I have not moved my user files off the SSD, I run my Oracle VMs from it and all my software except a few games are on it as well.
    I expect to get at least 5 years from it, hopefully more. By the time I have to replace it, a 1TB SSD will probably cost less than $50.

    I also have good backups.

    I agree though it would be good to know what is causing all the disk I/O.

    I looked at mine with the same filter, much quieter than yours:

    @Ztruker If you enable also the duration tab, you may also see, that the process is kinda high compared to aother processes in time and is producing a "lag". Mine literally writes all the time to disk, seems quieter than yours, but yours also does it. I wonder if this is maybe a bug. I didnt notice this before 1809 I think, or a year ago maybe. Wonder if there is some "debug" or "log" flag somehow set accidentally, which causes this behavior. Very problematic also seems to be Chrome in writing to disk because of its stupid cache. There were a lot of people complaining about this in the past, but Google never did anything about it. There is also no option to disable the cache and putting it onto another disk (like a 500MB RAM disk for example) is a bit tricky and doesnt work correctly too. I have a very fast Internet connection and would like to disable the cache actually, but there is no option for that. Browsing the web literalyl for 4 hours or so makes Chrome already write 20GB to disk or somethign stupid like that, if you use sites with images like tumblr, twitter, or video pages like youtube, twitch ect. The hibernate file also seems to be written randomly to it, with no reason at all. The pagefile too, even I am not even close in filling up my RAM.
