Hey guys, First of all, thank you so much for payng attention to my problem. Would really appreciate your help for resolving this problem. So, I have an Acer Aspire S7 392 Ultrabook (i7 version) with OEM Windows 8.1 PRO installed on it. (means, I've bought the laptop from a store with already this OS installed on it) My Windows Updater has totally gone crazy; it writes all the time 'Restart your PC to finish installing the updates' ... have done several times and happen nothing but writing the Update has failed. This 'Upgrade to Windows 10' notification always shows up and offers me to upgrade right now which I just cannot. Tried this for several times as well but happens nothing, it just restarts my laptop. Means, the updater is aint working, writes in the update history the update has been failed and nor the windows notification works. Already googled this problem and used the RegCure PRO software to resolve this matter but it didn't help at all. Have used CCleaner & Bleachbit too to fix my registry, nothing changed. Please, help. I really want to use Windows 10. Thanks.
