won't upgrade to windows 10 anniversay

Hi, did you upgrade from '7 or have you clean installed at any point?

If you upgraded, this may cause problems.

Have you run chkdsk C: /F?

Some people find that doing an in-place upgrade repair install of your existing version first may help.

Avoid Windows update as part of the process. Use your physical medium / iso as you have.

There is a cumulative update after the anniversary upgrade. Make sure you don't specify updates to be applied during the manual upgrade using the above.

Uninstall your AV.

Make sure you have at least 450 Mb of unallocated space on your system drive/partition, and enough room for Windows.old to be created (will be smaller than your existing Windows folder) + say 10Gb min.

Make sure you have no programs installed that modify the GUI.

Others will probably have specific solutions or ideas.

Your system specs don't give the model of your PC. Can you confirm it is listed by HP as Win 10 compatible?

Try reading the Windows update log:
Windows Update logs are now generated using ETW (Event Tracing for Windows).
Please run the Get-WindowsUpdateLog PowerShell command to convert ETW traces into a readable WindowsUpdate.log.

What would it cost you to do a clean install, bearing in mind people here often comment that leftovers from an upgrade can cause undesirable problems?

You could for about £38 buy a program that will transfer your programs and settings to a new installation (rather than doing it all manually).

A neighbour has asked me to update W10 Build 1511 to Build 1607 on her laptop which originally came with W7.

Have just spent an entire wasted day, each time the update goes ahead, then an hour or so later reverts back to 1511.
No updates are available with 1511 so that cannot be the reason why it cannot proceed, have performed chkdisc.

Her computer it would appear is somewhat messed up, Powershell or Command prompt admin operated so slowly as to render them useless, all 902 photos and documents were all filed in downloads, so finding the downloaded ISO proved impossible to locate as they were all changed to icons with no other available options.

All backups were installed on "C" and as she only used the O/S plus 1.1GB of space on the hard drive, yet 85GB of space is used up.

My question what is the best way to get out of this mess.

Run chkdsk & check SMART params to make sure it's worth continuing.
Back up everything that isn't properly backed up- I guess you've done that.

Try it- if you're an optimist, that is. Don't bother with SFC, DISM...

But if too much has been messed about with, sometimes you end up having to bite the bullet and clean install as you know...

Would that take a huge amount of time? .. if not too many programs installed.. best option.

Three unsuccessful attempts at clean install.....too many conflicting programmes.....MIGRATE-DATA operation.....0xc1900101-ox2000d.

Have tried M$ safe mode suggestions without success.....only one option left.....reinstall O/S, on new SSD, hopefully by not having to load a W7 disc and upgrading.

Have suggested replacing HDD with an SSD.....is it possible to clean install a W10 ISO on a new SSD?....as the original HDD loaded with W10 will not be connected.

Have you formatted the drive and wiped everything? - I'm wondering how you can have conflicting programs with a clean install.. and there's nothing to migrate..?

As to swapping the drive... best way is to have just the one drive in you wish to install windows onto.

If you have a different drive with Windows already on it, with an active primary partition, then you won't get the result you want.

What would you hope to gain from the old drive being present?

A clean install means you'll then have to reinstall programs, configure settings, move data back as necessary..

And you should be able to simply clean install the current build. There's no need to go back to '7 - that would be a really bad move. Your activation is tied to your hardware, so a clean install is fine.

Use a boot medium for Win 10 anniversary. Then you've got that for recovery, in-place upgrade install.... should you need it.

Thank you for replying....you are misunderstanding, perhaps I'm not making myself clear.

The HDD is clapped out and your above points are irrelevant.
What I wish to know is......Taking out the knackered HDD which had W10 already installed and authenticated, and replacing it with a BLANK SSD, this is a laptop.

Is it possible to install on the new SSD W10 1607 using the Windows Media ISO, and does the DVD ISO get me ONLINE in order to install.

PS....in other words do you have to be inside Windows for it to install an ISO.
