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,
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.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?
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
