Got a new Asus laptop with Windows 10 is always getting pounded by Disk usage = 100% when starting, booting, and then at various points of the day.

I reformatted my windows 10 machine to try to fix it. It was much faster for a few days then got slow again. I have scanned the machine, no viruses or malware that I know of.

I see all sorts of Disk pounders like:

  • Microsoft Compatibility Telemetry
  • Cortana
  • Superfetch
  • Search indexer
  • WMI
  • Other Service Hosts like Windows Event Log
  • Antimalware executable

There may be more to this list, and I only see Windows-system executables and services. Once again, no reason to believe I have malware. Fresh system here.

This being a vanilla system with only Starcraft 2 installed is totally killing me how it's so slow upon startup/standby. My mac and linux machines do not suffer this affliction.

Is anyone else dealing with this on the regular? How can I get my windows PC so that it comes back from standby without having disk usage shoot up to 100% for several minutes? I'm about to leave Windows forever. Could it somehow be my laptop hard drive in the Asus N550JX?

I have read each of the following and verified that I am not afflicted by any of the things listed in these other posts:

Windows 8 extremely high disk usage and slow IO

  • This post talks about windows 8 and is about a system that was used for a while getting worse over time. Mine is a vanilla system.

100% disk usage on windows 10

  • I do not have ACHI devices

  • I already have an SSD that came with this laptop.

  • Not at all the same question as either one of those 2. Only loosely related with a few tips that might intersect. Has nothing to do with AHCI etc – Nicholas DiPiazza Jun 01 '17 at 14:35
  • https://superuser.com/questions/1182651/windows-10-100-disk-usage-after-startup - this one might be related those other two are not – Nicholas DiPiazza Jun 01 '17 at 14:36
  • You indicated there is high disk usage, the possible duplicate specifically mentions this is a possible problem, with your AHCI driver. Please post your analyst, that rules out the problem, described in the possible duplicate I suggested. – Ramhound Jun 01 '17 at 14:38
  • Have you tried to disable Cortana? You can't disable Telemetry since you are not using Windows 10 Enterprise. If you were to disable, `SuperFetch`, your performance would decrease. You could disable the search indexer, but that would of course, prevent you from indexing your files on your system. Windows Event log isn't the problem. – Ramhound Jun 01 '17 at 14:44
  • Have you verified your disk is healthy? Long period of times, being unable to access folders and (for example starting task manager), is often associated with a failing disk due to the long I/O events. Windows will eventually invalidate those I/O requests but it takes awhile. – Ramhound Jun 01 '17 at 14:44
  • i'm going to try a completely separate SSD to verify this is not the problem. I will let you know. – Nicholas DiPiazza Jun 01 '17 at 14:47
  • Use [WPT to analyze the issue](https://superuser.com/a/1148857/174557) instead of hibernation select standby/resume. Drag & drop Disk activity graph to analyze pane and [analyze it](https://channel9.msdn.com/Shows/Defrag-Tools/Defrag-Tools-44-WPT-DiskIO-Analysis) – magicandre1981 Jun 01 '17 at 16:42
  • Take a boot trace with Windows Performance Toolkit you can download from here: [Windows Performance Toolkit](https://developer.microsoft.com/en-us/windows/hardware/windows-assessment-deployment-kit) Here is a tutorial on how to record a boot trace: [How to use wpr to record boot sequence](https://zinetek.wordpress.com/2015/12/16/how-to-use-wpr-to-record-boot-sequence/) Compress the trace and shere it. –  Jun 02 '17 at 10:36
  • Update - When I replaced the hard drive with a Samsung solid state drive, now the computer is blazing fast. – Nicholas DiPiazza Jul 06 '17 at 02:49
