we had tech support company to install windows 10 in aug. 16. we had wireless internet connection at that time. in the last week of Sept 16 they computer did an automatic update and we lost the wireless connection. we took it back to the store to have them fix it, but was advised that they couldn't resolve the issue after 4 days. we took the cu home and tried to do a restore on the computer after reading some of the postings for this problem. now the computer is doing a loop in the restore and its going on 3 hours. is there a way to stop the restore without losing anything?
