class not registered

Question

I can not do anything cant go on my task bar cant click on any apps it always says class not registered

Answer 1

Then you need to work from the Repair Mode or Booted Media where Windows errors cannot interfere. I gave you these steps in my first post.

The error normally refers to File System errors on the hard drive which need to be repaired with Disk Check. It can also mean the hard drive is failing which can be checked with the manufacturer's hard drive diagnostics:

Best is to use the manufacturer's own if there is one, otherwise use Seatools bootable long test: http://blog.nowherelan.com/2013/04/04/boot-seat...

Use whichever method works in this link to get into Repair Mode so you can run System Restore to a point before this problem began, use the Uninstall Updates button, access the Command Prompt to run the System File Checker and a Disk Check, try replacing your account in order to save the install, or do a Reset: https://www.tenforums.com/tutorials/2294-advanc...

Easiest is to force shutdown by holding in the power button three times until it starts into Repair Mode. Once in the Repair Mode try the numbered steps below.

It may be necessary to create bootable media on another PC to access Advanced Startup Options to try repairs, a Reset or do the Clean install. The bootable media has it's own set of files so that repairs or Reset might work better, doesn't require a password, and you'll have it to do a much better Clean Install.

To create Windows 10 Installation Media on another PC install Media Creation Tool and follow the directions here: http://windows.microsoft.com/en-us/windows-10/m.... Uncheck the box for Recommended Settings to choose the exact version and bit rate for the target PC only.

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key given here: https://www.sysnative.com/forums/hardware-tutor...

If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

Choose the boot device as a UEFI device if offered, on second screen choose Repair Your Computer, then Advanced Troubleshoot Options, then:

1. Try a System Restore,
2. If that fails try Uninstall Updates,
3. Open the Command Prompt to:

a) run System File Checker: https://www.wintips.org/how-to-run-sfc-offline-...

b) a full Disk Check: https://www.groovypost.com/howto/check-hard-dri...

c) Enable the built-in hidden Admin to sign into create a new Admin account to replace yours:

http://www.howtogeek.com/226540/how-to-create-a...

4. If those fail then go back to Troubleshoot Options to do a Reset.

If that fails choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, click Next to let it create needed partitions and start install - this makes it foolproof. Everything needed to get the best possible Clean Install is here: http://answers.microsoft.com/en-us/windows/wiki.... It is a better install than any amount of money can buy and a great learning experience that will make you the master of your PC because you will learn what works best and how to apply it with your own hands.

If you have files that aren't backed up you can use the same bootable media to try to rescue your files using these methods: http://answers.microsoft.com/en-us/windows/wiki...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
