I had windows 8.1 and had opted for the free upgrade... I liked using Win 10... but some days back I was trying out installing some new software and I guess it was infected.. I abandoned it halfway ... but it had installed some adware already.
I removed the adware but now I am observing the machine has become slow... it takes 5 mins to shutdown... so I guess something is wrong.
I want to reinstall the OS, but now will my win 8.1 be upgraded to Win 10 OR it will be 8.1 when I reinstall it.
I like win 10 and don't want to lose it OR pay for buying a new win 10.
