Please provide me solution
We try all thing and i am trying from last 7 days still not reslove
Please please support me
7 days that's not long at all. I was at it for 2.5 months. There are many causes why it won't install and most of the simple solutions offered don't work.
Officially you are told not to attempt the update unless you have been offered the update via the normal invitation. That can then fail which puts you in the same place whether you'd used the download screen.
There are two mains boots the first on the drivers you have got and the final boot at circa 70%. If you aren't at 70% you are well back. Where I say you end of playing snakes and ladders between the two. Once you slip back down you have to get back up. My experience was that some of the update drivers were a problem. You are told to update the drivers, don't at first and if you do keep a copy of the previous one. There are driver free tools available but they can cause more harm than good.
As far as errors are concerned you don't see the full error code untill you use the ISO method but Don't take the recommended option to update the drivers in that since it can introduce problematic drivers. You need the error codes to place you where you are when it failed. Snakes and ladders bit.
The log files if read correctly will help. The final boot at 70% plus is where the memory integrity test is applied on the drivers. There is a separate tool which will tell you which drivers may fail this. If hitting above 70%, failing and it's a possible driver issue then well worth running the memory integrity tool. I just had one driver than failed this that caused me two months of grief... just one duff driver that wasn't being used but the software
As far as I can see what Microsoft has done is reverted the update to how it was in Windows 7/8 to 10. Drivers had to match to cross that bridge then the added complication is memory integrity on the drivers. Old ones without the appropriate security won't pass beyond 70%.
You must also remove all anti virus software other than Windows Defender and any other low level non Microsoft smart software for doing clever stuff. That's bound to fail. It will trip up on that. The log files if read correctly point that out. That's what the Microsoft help experts find on here when you share your log files if it comes to that.
Farbar tool is the other one the experts like you to run. You eyeball the output. It was at that stage I concluded it wasn't a rogue program but some driver that was proving impossible to find.
The cyclical stuff you read to do made no difference. They all say the same. Stop this service, start this service. Clear this, clear that.
After all of this 24h2 will update your drivers.
