Windows (7, 8, 10) - Is a clean install better than an upgrade and if so why? (be specific)


I'd like to know if given an existing Windows PC, are there any concrete reasons why a clean install should be performed over an update.


Articles like this one at How to Geek refer to "bloatware" and "clutter" on the PC and rightly suggest that this might not be something that you want on the upgraded PC. This post on Super User refers to "crashes" and upgrades being "problematic". Both are fairly non specific as to what these problems might be though.


If I'm happy that there is no bloatware or clutter on the PC prior to the upgrade, are there any specific known issues that can cause specific problems when upgrading rather than clean installing?


Or is it just a case of being sure?



Answer



For the free upgrade of Windows 10 to apply, you NEED to upgrade. Its as simple as that. This will bring you your settings with you, and best of all, because it will install new system components, the entire windows framework will be new (errors from the past will be fixed)


I had a problem on one of my pc's where windows update was broken. I used the offline upgrade tool to upgrade that particular pc and windows update is fixed again. yay.


Once you upgraded to windows 10, you can use the buildin functionality to make it go to a clean state from whitin windows 10. This will allow you to start fresh which will help get your windows back to speed if it was terribly slow in the past. It will keep windows 10 installed, just remove everything (you can select what to keep) and go on from there. Doing a clean-up this way will also remove any bloatware. Windows framework is already new from the upgrade, and the clean will remove any infections related to the files you had unless you choose to keep those.
