I still wanna know what "scratches" we are talkin about here...
Sorry
I meant "from scratch." English is my second language, that's why this blunder.
Thank you for the link Computer_Commando
There's a fragment from there:
Windows Updates will need to be checked and reinstalled again.
Seems like Windows will be updated from
scratch (in case when Win7 installation disc doesn't have SP1). And I don't like this.
