Walter has an old Dell i7 laptop that he loaned to a friend. But lately, the Firefox browser won't load a page until you move a mouse and the page pops up. What is that all about? Leo says it sounds like a bug in Firefox that is waiting for an input. It's called a "signal event loop." It may be a failed install of Windows 10 is likely the culprit. So back up the data, wipe the drive, and reinstall Windows 10. That should solve the issue.
After users complained of having their data, and even their profiles deleted, Microsoft has pulled the Windows 10 Fall 1809 update. Leo hasn't had that problem, however. But Microsoft has paused until they can figure out what's up.
After numerous complaints that users were having all their files deleted during upgrading, Microsoft has pulled their Fall 1809 Windows 10 update and recommends to users who have lost files to use Recuva to get them back (but only in some cases). This is a similar issue that plagued their 1803 update last Spring. Another issue is that your profile may get deleted as well! So it's really serious issue and Microsoft was wise to pull it back. But it's baffling that since millions are part of the Windows 10 beta test, how this could happen without Microsoft seeing it coming.
Nick doesn't want to update to the Windows 10 1803 update. How can he keep from updating? Leo says that he can defer it by telling Windows he's on a metered connection (in network settings), but ultimately, he's going to have to bite the bullet. Leo says that he can save the update on a thumb drive, but Avast could be causing issues with the update. Nick should check out this article on windowscentral.com for common problems and fixes.
Jim is running Windows 10 with an old Apple Airport. He's been dealing with a lot of buffering and connections that time out when he clicks on links in Chrome. Is it the router? Leo says it probably isn't. It's most likely a problem with the Windows File Association Database. It can't seem to find the file it's looking for. Leo says to reset the file associations in the basic Control Panel. It's in the app section under "Default Programs." It will also reset his default browser back to Edge, so he'll have to redo his default browser setting as well.
