Steve has an old Gateway computer and wants to know if he can update to the latest Windows 10 Fall Creators update. It won't install, failing at 84%. It can restore the previous version, but he doesn't know why he can't update. Leo says that it should since Microsoft has opened it up to all computers now. But if he hasn't applied all the previous hotfixes, it may fail.
There may be a hardware issue as well. He shouldn't force it, though. It could make things worse. He should just try to install it every few weeks until it works. Eventually, Microsoft will have whatever his computer needs to install it, but it's not required — only the Security hotfixes are. Steve should keep doing those regularly.
