Since updating to win 10, I'm experiencing issues with my disk usage. From time to time (sometimes every 10 minutes, sometimes once every few hours) my system becomes unresponsive because the disk usage is 100%. It usually takes one or two minutes for this blocking to be resolved.
If I have the task manager open, it says the read and write speeds are 0, but still my disk is being used for 100%. I'd expect there's some process blocking IO access to all the others, so I've tried watching the performance monitor for heavy processess, but since I can only see the current read/write speed of each process/service, I haven't been able to pinpoint any abnormal behavior.
Can anyone show me how to diagnose this kind of issue please? As you can imagine it does reduce my productivity, and to be honest I hate it when my pc behaves unexpectatly :p
Regards, klmdb
PS: I've googled 100% disk usage issues and came across many different suggestions (like disabling some windows services), but to be honest I'd prefere not to 'solve' the problem by cutting off pieces of the intended operation of my OS.
Do you have any 3rd party antivirus installied? If yes try to uninstall it – Ivan Viktorovic – 2015-08-19T11:44:51.673
No I only have windows defender. – klmdb – 2015-08-19T12:27:08.397
Have you tried to stop it Windows Defender for a while to see if the situation would improve. Also check the system event logs for Event ID129 as per this Microsoft KB.
– Techpumpkin_WD – 2015-08-19T14:14:51.263Awesome! I did check the system events and found the exact issue that you linked. I applied the provided solution. Hopefully that does the trick. Thanks very much! If you provide your tip as a solution, and maybe describe how you knew what to look for, I can accept it and you get your hard earned credit :) – klmdb – 2015-08-19T14:58:38.953
hmmm still getting the same behavior (maybe a little less frequent), and also still getting id129 events. Investigating the event id further... – klmdb – 2015-08-20T18:10:36.470
Windows 10 starts to compress all files on your hard drive after upgrade! Just let your computer run idle for a few hours, depending how much data you have... it will just churn the HDD. Also, it does a ton of Indexing for searches. I had this sympton for first week... where I left the PC idle and then the HDD started doing a ton of work. It shouldnt really block your machine, just make it a bit slower. – Piotr Kula – 2015-08-30T17:59:03.680
Hi, could you try running Process Monitor while you experience the problem. Once you gather enough events during the problematic period, stop the capturing
– Vlastimil Ovčáčík – 2015-12-07T11:10:20.877Ctrl+E
, go to Tools > File summary.... Examine each column for excessive values, especially the Read bytes and Write bytes. You can share screenshot with us, or even all the captured system events, but it may leak some private information (name, file paths etc.).I assume you've tried turning Cortana off? – Zibbobz – 2018-04-04T23:12:12.790
