Windows 10: Anniversary: upgrade vs fresh install

Hey there,
I've upgraded to Anniversary release using Upgrade Assistant, having Win 10 64-bit Pro version installed and everything is looking good until now.

My concern is related to the programs functionality that was already installed, is this a good choice are there any cons or it's better to perform a fresh install using the Media creation tool / latest ISO images?

Thanks,

:)

 

Is it possible to upgrade to Creators Update from v.1511?

DONE!!!! I've upgraded without problem from v. 1511. I couldn't install Anniversary update (tried updating and fresh install and it was impossible) and this installation went OK.

THANKS a lot!

 

Windows 10 upgrade failed. Now it won't download again.

Use the Media Creation Tool to install right now. Uses fresh code and ignores prior installs or bad downloads ect.

You must have 7sp1 or 8.1 with activation.

Download the correct tool 32 vs 64 bit.

You are going to do an upgrade install, upgrade this pc now. Download starts immediately.

 

Which ever method used to upgrade , result should be same. If it upgraded well, without problems, that means you had nice, clean and properly working system and I can see no reason for clean install.
Here's my example, same computer but with some major HW changes including motherboard:
W7 > W7 Sp1 W8 > 8,1 and every single W10 insider update/upgrade since day one. Few times some programs would be uninstalled or stopped from working but after reinstalling them worked as before.
Most upgrade problems come with resident AVs other than WD and problematic drivers for some HW along with too little space on system disk.
I did take some precaution though, I always make Macrium Reflect full system backup before major updates/upgrades and make ISO out of downloaded upgrade using ESD to ISO program you can find in Tutorials section. That gives me an option to do clean install if necessary without having to download it again.

 

IMHO, If it's working fine, with no obvious issues, don't worry about it. If something doesn't seem right, do a clean install and see if that fixes it. I've had glitches in the past from upgrades. Not every time, but some times. After a clean install those issues were gone.

 

Yes, an upgrade is known to cause some issues, but you can perform some maintenance to ensure, that everything is fine.

Run CMD as admin and copy/paste/enter underlined commands (preferably one by one):

fsutil usn deletejournal /d /n c:

This will remove any file history left from Windows 7, if your Windows is installed on partition C.

chkdsk /scan

This one never hurts, it is a fast basic HDD scan

Dism /Online /Cleanup-Image /CheckHealth

It should report: "No component store corruption detected."

winmgmt /salvagerepository

It should report: "WMI repository is consistent."

sfc /scannow

It should report: "Windows Resource Protection did not find any integrity violations."

Dism /Online /Cleanup-Image /StartComponentCleanup

It should report: "The operation completed successfully." (It can be only 20%, you can ignore that)

cleanmgr /sageset:65535 & cleanmgr /sagerun:65535

This will clean up everything (you choose), including Windows.old folder, if you do not want to revert back to Windows 7.

 

It's all clear now, thank you all *Smile
