Windows 10: Explorer.exe Class not registered and other issues after CreatorUpdate

I updated to the Creator Update yesterday and have spent almost 24 hours trying to fix all the issues it has created with my system.

The most irritating is the one in the title, if I wasn't using Clover and the Task Manager I wouldn't be able to access anything on my system. I attempt to get to the recovery from the Control Panel, the option that says "if you're having problems with your PC, go to settings and try resetting it", however I get the Explorer.exe Class not Registered error. I have tried the regsvr32 method, I know it's not a Microsoft Edge issue, I tried dcomcnfg, and I tried SFC, which said it found no errors at all.

I have also tried to roll back to the Anniversary, however my keyboard nor mouse are present and none of their inputs are registered. I have tried three or four different usb ports for both the mouse and the keyboard with no luck. Let me clarify that I tried all of that in the advanced boot menu by locking the computer and shift-clicking restart. I only get any sort of progress in safe mode. For some reason the Windows 10 Settings will actually show up in safe mode, but once I click the Get Started button to roll back I receive the "This won't take long screen" which then freezes up and crashes.

I attempted an In-place upgrade which from what I noticed accomplished nothing and since the usb I made was for the anniversary version the only thing I could do there is a clean install which if at all possible I would love to avoid. Any help would be greatly appreciated and I will post a Speccy TXT of my system.

Explorer.exe Class Not Registered

Thank you for sharing us this workaround. Glad to know that you were able to sort out the issue. Other community members who may experience the same issue will find this helpful.

All the best!

 

Hi, I'm afraid this isn't going to help you, but may help others reading this who are considering the upgrade.

Before you upgrade, create a disk image ('Backup windows') using e.g. Macrium Reflect (free), with your image on external storage, and create Macrium's boot disk. (We continually and strongly recommend disk imaging).

With that disk image and boot disk, you can restore your PC to the state it was in before the (failed) upgrade without technical help.

 

I am starting to believe that my only option is a clean install. I have important data backed up on a HDD, but no disk image sadly.

Yes, I think it's very valid advice and very worth listening to so you don't find yourself in my situation.

 

Run CMD as admin and copy/paste:

Code: schtasks /Change /TN "Microsoft\Windows\TextServicesFramework\MsCtfMonitor" /Enable schtasks /Run /TN "Microsoft\Windows\TextServicesFramework\MsCtfMonitor"[/quote]

may offer a thought or so on class not registered...

and prompts the thought... does it matter if Edge isn't your default when you upgrade?

Sadly this did not help. I am still unable to click on my account when I reach the pre boot

 

I was able to finally try to click on the roll back option, but it was unable so in the end I was forced to do a clean install. Thank you both for the help

 

Hope you didn't lose too much.

Now you have a clean functional system, this is when to start using disk imaging routinely to give you a second chance when things go wrong, and avoid clean installing.

Here's my write-up on the value of disk imaging.

Creating disk images lets you restore Windows and all your imaged disks and partitions to a previous working state from compressed copies you have created and kept updated on external storage media, quickly and probably without technical help.

You can recover from:
- a failed disk drive (restore to a new one)
- ransomware (which encrypts your disk)
- user error
- unrecoverable problems from failed updates to problem programs
- unbootable PC (hardware faults aside)

Images also act as a full backup- you can extract files too.

You can even use images to help you move more easily and quickly to a new PC.
Can be used with Laplink software to transfer your build automatically to another PC

Imaging can even help you sleep at night knowing you have a second chance.

Many here recommend Macrium Reflect (free) as a good robust solution and more reliable than some others. It’s
- more feature rich
- more flexible
- more reliable
than Windows Backup and Restore system images.

It's well supported with videos, help and a responsive forum.

There are other such programs, free/commercial, some with simpler interfaces, but Macrium R is one of the most robust and reliable.

How long does it take?
SSD+ USB3 - maybe 15 mins for the first system image, less thereafter
HDD + USB2 - maybe 40-50 mins
That’s with little personal data, few programs installed.
- of course, depends how much you have on C:
(You can and should image all your partitions and disks)

Once you've created your first image, keep it updated with e.g. differential imaging- which images just changes from the first image, more quickly, and creates a smaller image file.

You need a backup medium - say- twice as large as the total amount of data you are imaging to keep a reasonable number of differential images. This will vary dependent on the number of images you keep, so is only a rough practical guide.

Some comment that system restore isn't always reliable; if it works and solves the problem, great. But sometimes restores won't work or fail. And of course a restore point only covers a limited number of aspects of the system. That’s where disk imaging comes in.

(There's a tutorial on Macrium in the Tutorials section, and a couple of videos in the user videos section on this forum)

I luckily did not as I had a reliable backup of my entire user folder on an external HDD. I will definitely follow your advice on creating a disk image however. I downloaded Macrium right away once I got the system reinstalled.
