Now that more that 14 million users are running Windows 10 on their computers, it might be necessary to look into some of the problems or issues an user can face after the upgrade. As a first-hand experienced person of these problems, I have executed these solutions that I'll be delineating below & they have worked out as anticipated.
- Even if you were using Mozilla Firefox as your default browser on Windows 7 or 8 or 8.1, then Microsoft will automatically make Microsoft Edge (IE's next generation) as the default browser. Even though Mozilla's CEO was furious with Microsoft over the default browser setting changed, you can still make the switch easily. After my upgrade, I was unable to browse to google.com on Firefox even after I made the default browser setting change. Apparently, my university's IT dept. thought it was caused from a antivirus conflict as Windows Defender & my previously installed Avast were cross-talking with each other & not allowing sites to be browsed. So they uninstalled the Avast & made Windows Defender as the default antivirus. But that only solved the issue temporarily. Before I was only able to browse my university's links with Firefox & Chrome. Now Chrome allowed me to browse any sites whatsoever. Firefox was still acting up. Apparently, after little search I discovered that this issue had been reported by users with Windows 8 long time ago. It's an issue with security certificate of HTTP & HTTPS sites. The fix is pretty simple as the techies described here. The main thing you need to know is that:
- Go to Control Panel → Network and Internet → Internet Options → Content → Certificates → Trusted Root Certification Authorities. Select the Microsoft Family Safety certificate, then click Export…. Answer No, do not export the private key. Either of the two .CER formats is fine. Save it to any convenient temporary location, such as
familysafety.ceron your Desktop. Then, you need to tell Firefox to trust the certificate that you just exported. In the Firefox menu, choose Options → Advanced → Certificates → View Certificates → Authorities → Import…. Select the
familysafety.certhat you had just saved. Select Trust this CA to identify websites, then click OK, and close the Options dialog.
- Then for some reason my audio driver in Toshiba Satellite S55 was not being able to be detected which allowed me no sound from my laptop's speakers whatsoever. Again, after some googling, I discovered that this issue was happening previously with Windows users long time ago. The fix is also quite simple. Here's what you need to know.
- Click "Start". Type "devmgmt.msc" (without the quotes) to launch Device Manager. Expand the "Sound, video and game controllers" node and note the list of audio devices. In this case, I have one audio device, and by the "High Definition Audio Device" name I deduce that I have the class driver installed. (If the device name included a company name, I would infer that I had a vendor driver installed.) Right-click the device you want to change the software on. Windows offers to automatically detect the driver that should be installed. No thanks, we want to pick a particular driver. Windows asks where we want to look - do we have a set of driver files, or is the driver already in the list of installed drivers? In this case, we want to look at the list of drivers for this hardware that are already installed. Windows shows us a list of drivers that are already installed and usable for this hardware. At this point you would expect to see two drivers listed: the vendor driver, and "High Definition Audio Device." To install the class driver, pick "High Definition Audio Device" and click "Next." Then "High Definition Audio Device" is a class driver, so you get this warning. Click "Yes." Windows does its thing... ... and eventually tells you that it's done. If your audio device was in use, you may get the "you have to restart" message. Regardless, click "Close". If you got the "you will need to restart" message, Windows helpfully offers to restart right away. Make sure you're ready for a restart (no unsaved documents or anything) and restart either by clicking "Yes" or by using the Start menu.
- Although you can install Windows 10 from Windows 7 or 8 or 8.1, without having to lose any data whatsoever, from personal experience so far, if you want to get the most out of Windows 10, you need to do a fresh install which you can do after securing your data somewhere else. Windows will erase all previous data & install Windows 10 as a brand new OS when you buy a computer, for instance. Please note, if you do this fresh install, you will not be able to revert back to your previous Windows version (7 or 8 or 8.1). Here's how you can do it.
