1- I recently updatet my laptop from W7 to W10 but I have difficulty in actiavtion of my license. In W7 I used to receive a notification that my OS was not activated something which I had been struggling for a while, but W7 came with this laptop when I bought it, its a Home Premium.
I have used my W7 license but it does not accept it and it only gives me two options, either change the key or go to the store, what do I need to do to accept this license?
2- There is a windows.old folder seems to contain more than 40 Gb, can I just delete it without affecting the current OS?
3- Under the program files x86 folder there are my previous installed programs but don't seem to have access to them through start button. Do I need to install those programs again? Can I delete these files too?
4- Audio and Elan touch pad mouse are not working, is it possible to reinstall them? I can only see W7 drivers at Acer for these two devices.
Thanks in advance
