Windows 10: Announcing Windows 10 Insider Fast+Skip Ahead Build 17040 for PC

I've just done that too.

 

70% installing now, its got better.

 

Well, I'm late to the show. I'll have to meander over to my IP partition. For AMD finally too I see. *Smile

 

I might break my previous record today. Since December 2016 and beginning of UUP, I've never had upgrade ready for restart (Restart now button to appear) under three hours, record time at the moment being 3:15.

 

Kari, Siemens announced today that they were closing their plant in Leipzig, so maybe you now have more "bandbreite"*Wink

 

LOL!

Bandwidth is not an issue, the download comes at full speed, being the fastest part of the process. I do not have a faintest clue what it is that makes my upgrades so slow.

Checking Task Manager, it's not a resource issue. Windows Setup (Modern Setup Host) is only using 2 to 6% CPU, writing to disk really slow (3 to 8 MBps).

 

Finally to restart at the second attempt.

 

Writing speed here was around 80 to 90 MBps. Dig in that direction... Is this in VM? What happened on that December 2016..

 

I can't find any reason why upgrade, the Modern Setup Host process writes to disk so slowly.

No, an Asus laptop. Weird thing is until a month and a half ago I was using another Asus laptop until it just died, this one is almost similar, refurbished directly from Asus with warranty. Two Asus / Intel / NVidia) laptops, both working just fine (until the first one died *Wink), both taking from four and a half hours to 7 hours to upgrade (three and a half to over 5 hours to "Restart now", then about 90 minutes to restart and to get to upgraded desktop).

Microsoft stopped delivering feature / build upgrades as ESD and switched to UUP. I never had any issues with ESD upgrades, it was an hour to hour and a half including the restart phase.

Does not look good, I guess I will not break record tonight as I thought earlier:

 

Wasn't suggesting an upgrade. Just checking what is slowing down writing to disk. But then, you are a geek more than enough, to do whatever is possible with hardware you have...

That times are not fun to deal with.

 

I've noticed at about 60% into installation phase Modern Setup Host kicks in and eats up as much as 70% of an 8 core AMD CPU. Must be processing a lot of data. Then around 70% into it drops to around 13/15% for awhile. Don't know how may threads or cores it's using, though.

 

Concerning this Known Issue:

Insiders with certain third party antiviruses and OneDrive Files on Demand enabled may see an error citing “OneDrive cannot connect to Windows”.

@Kari
I know we both had this problem, and I have found the alleged culprit. I tested it this morning on two different 17035 Insider OS's prior to the release of 17040. It is a conflict between OneDrive FOD and Macrium. I had done a clean install last Monday of 17035, and all was fine. Until I installed Macrium with both Image Guardian and CBT. Then FOD promptly broke. I uninstalled Macrium completely, all 4 options on the uninstall screen, everything. Rebooted and reinstalled Macrium without Image Guardian and without CBT. Set the OneDrive to the proper setting to save space, and all worked perfectly! Rebooted and all held, still worked perfectly. I just did 17040 on top of 17035, and all held, all still works perfectly.

There is a conflict, and I'm not sure where to point the finger. I'm suspecting the Image Guardian service, not MR's fault, just something changed maybe in the Windows permissions/security that made it get ill.

Again, if you totally uninstall Macrium and reinstall without those 2 options, it will work.

*Warning*Arrow Copy and save your backup definitions first, they will get deleted. Usually in Reflect folder under your User\Documents. Copy them back after MR reinstall.

30 minutes in > Restart....

 

Thanks for sharing that, Dick! I will most definitely test it.
