Windows 10: Why does MS download such LARGE files when logon?
Caledon Ken said:
Hi Ken, That part of my reply was only as an answer to your original reply. Just this evening, it did it again (20 plus minutes downloading so far 400+MB data and there are no updates in windows or defender. This ex win8.1 NEW HP was completely wiped and the free win 10 clean install was done (HP bloatware AND the 8.1/10 update left me with a LOOOOOONG bootup and slow system so I found the post on wiping the HDD and clean installing this win 10). Although I HAD to have the MS account (according to the prompts) I do not use cloud, MS (any more than I have to), nor want or care to use 'cortana'. I would like to explore the possible 'cortana' automatic downloading thing because of the MANY IP's in the resource monitor (network window) leads to a large number of (searched) MS controlled IP's. It is so annoying to log in wanting to do some surfing, emails but having the laptop locked up doing this HUGE download. This isn't my primary system so it isn't turned on as often as my win 7 machine (which does not have this quirk). Lets please see if it is this auto-Cortana non-prompted force-ware download is causing this, and stop it from locking my system?
Storageman, your idea sounds logical, can I just find that file and delete it, or can I just 'disable' (simply) this 'cortana' unwelcome demand of my time and system?
Hi Mike, it isn't sync-ing with anything in my house. You see, I am too dumb for a 'smart' phone and I have no 'smart' or 'wifi' devices/appliances in my home. The large list of IP's that I look up mostly come back as a MS owned/leased IP. I don't 'cloud', or use a MS account, and don't know how too anyway. I just want to be able to log on and search/email (and sometimes 'smurf' the net). Not 'connected' in the way many are today.
Adding to my prior, was not feeling well the last 1 1/2 months, I do apologize that I was not in the forum and responding sooner. Although it is extremely annoying, it catches me every time I do start this laptop up (you would think I would learn to 'start' it up and go eat breakfast or something until it is done). I figure why does MS 'stress' the system (and my nerves). I also do not understand why MS seems to be so invasive? Sign of the times, I suppose. Please excuse me in advance, if I do not get back for a couple of weeks, for any responses posted? I do hope it is an easy task, to disable this 'cortana' application (if factually it is causing this).
OK, done some reading (some of which I actually understood), and ask what portion of 'cortana' is needing all this data? Is it data that 'helps' by having it locally, or what? I cannot see how so much data can be useful for every machine. Not only does it take all my bandwidth until it is done (cannot IE search or do anything else that would use my connection), but does it 'stay' on my system? Why does MS/win 10 want/need all this data when I start/connect?

Reason: added information
Is Windows Defenders disabled? It's definitions can be that large sometimes.
Go to the control panel and click on Windows Defender. It'll say it's off if it's off.
This is an interesting idea and could help confirm if Cortana, Defender or any other app.

OP - Per your quote "Storageman, your idea sounds logical, can I just find that file and delete it, or can I just 'disable' (simply) this 'cortana' unwelcome demand of my time and system?" - The name of the file is "SearchUI.exe". He is the downloader. What I did was search for his name on my WINDOWS drive (Note Directory name = "C:/windows/SystemApps/Microsoft.Windows.Cortana.cw5n1h2txyewy) and then I took "ownership" of the directory (note TenForums has a tutorial to add "Take Ownership" to the right click pull down menu - I forgot the link - you will have to search for it) and then I just RENAMED "SearchUI.exe" to "SearchUI.old".
Please note that I've observed several (not all) cumulative updates that will re-install "SearchUI.exe", which will require you to do the procedure again.
That will stop Cortana from downloading any info !
FYI - I forgot that you will receive once a week 3 new "Cortana Error events" in your event log. Just disregard them.
IT IS DONE! This morning, I checked to see if there was a reply and SURPRISE! No more huge files downloading. I suspect yesterday's download was maybe 'queued' and not interruptible (at the time I did the 'ownership' and rename)? Thank you storageman, so much, for your SPOT-ON diagnosis, and solution. IF people have the 'cortana' disabled, MS should have this 'SearchUI' disabled as well. Just another instance of MS not thinking (or is there another reason for it to be running?). Anyway, I can NOW log onto my laptop and use it right away instead of waiting for these danged time/resources delay!
The computer run into BSOD for several times, blaming for L1C63x64.sys, which I found is related to NDIS Miniport Driver f , C:\WINDOWS\system32\drivers\L1C63x64.sys.
My Qualcomm driver is the newest version. I really appreciate you if you could...
I don't have the BSOD info yet, and from what I can tell it varies anyway. The first error I received was 0x8007045d but after a clean install of Windows 10 I instead got a BSOD talking about IRQL_NOT_LESS_OR_EQUAL.
When I get home I want to try...
I love Windows 10 but this may be the most annoying feature so far for me and I have no clue how to turn it off. I've searched online and all results concern windows 8/7/vista... and not only were there no real solutions but there is nothing about...
I have two excessively large system files located in C:\Windows\:
The first is 43.4 GB and the second is 26.6 GB. Together, they constitute 30% of my total disk...
