Yesterday, I upgraded my laptop from Windows 8.1 to Windows 10, and I'm really liking the new upgrade. It's fast, has new features I like, and looks good. But now that I have installed Skyrim, it won't run. Here's a little bit of backdrop:

On July 23, 2015, I had a pretty major issue with my laptop that I still don't know the cause to. It started with getting an application error for LogonUI.exe, which caused me to be unable to log into my laptop. Since it started into Safe Mode just fine, I was able to try and figure it out there. Since the Windows Event Viewer alluded to my graphics drivers, I tried reinstalling my AMD Catalyst Control Center, but after uninstalling it, I couldn't reinstall it. So, I tried AMD's removal tool, and that somehow completely screwed up my Windows installation and I had to restore it from HP's restore partition on the hard drive. I got everything all figured out just before Windows 10's release date.

Because of this issue and the fact that Windows 10 would be out very quickly, I decided not to reinstall my games (including Skyrim and Cities: Skylines) until Windows 10 was installed.

Now that Windows 10 is installed, I have begun to reinstall all of my games, starting with my two Steam games. Cities: Skylines runs just fine, but Skyrim doesn't run at all. When I installed it for the first time under Windows 10, I installed all of my mods I had backed up before I even launched the game for the first time (I know, smart, right?). When I went to launch it, I got three errors, all about missing dynamic link library files. The only one I can remember was that it said "d3dx9.dll" or something very similar (maybe d3dx9_43.dll) was missing. That's a file related to DirectX, which I thought was a little strange since I should have DirectX 12 because I'm on Windows 10. So, I went and installed what I presume to be DirectX 9, and it went all fine and dandy. Skyrim now launches, but there's a new issue. It crashes right after the Bethesda logo.

Since I have had that issue with the game crashing after the Bethesda logo, I figured it was a mod related issue, so I just went ahead and reinstalled the game, but forgot to "remove" the mods in the Nexus Mod Manager. So, I removed the mods in the Nexus Mod Manager. Still, the same crash occurred. So, I went and uninstalled the game again, but this time, I went into my Steam folder and deleted the remnants of the Skyrim installation. Then, I shut my computer off for the night.

Now, I'm installing the game again, and I will launch it clean this time. For the time being, I would appreciate it if someone could shed some light on this situation.

?EDIT: Actually, it did turn out to have something to do with the mods. All I needed to do was just remove the last remaining bits of the Skyrim installation, reinstall it and it runs fine now. I just need to configure its AMD Catalyst Control Center profile so it performs better.

Crashing right after the logo is indicative of a missing or out-of-order master to a module. It could be that W10 messed up the load order somehow, as it's not determined by the "modified by" date anymore (which was a kludgey way to do it in the first place).

The next time you get that error:

The "LogonUI" application in Windows manages your startup and shutdown graphical user interface (GUI), which shows the Windows logo on your screen and the status of your shutdown.

It also displays the login screen that you see when you first start up the PC. A corruption in this application might lead to problems booting up and shutting down, such as freezing.

Follow these methods and check if it helps.

Method 1:

Run System Maintenance troubleshooter to diagnose the exact issue.

Follow the steps mentioned below.

a. Press Windows key + W.
b. Type Troubleshooter in the Search box and hit enter.
c. Select System and Security.
d. Select System Maintenance under System options.
e. Follow the on-screen instructions to run the troubleshooter.

Method 2:

This might be an issue if any of the system files are corrupted, running System File Checker [SFC] scan might help you to get rid of this error message at the startup.

SFC scan replaces the corrupted system files with the original version of Windows files on the computer.

Use the System File Checker tool to troubleshoot missing or corrupted system files on Windows 8.1

However, in your case most probably:

Corrupted AMD Display Driver files, causes the logonui.exe to crash.

1.Uninstall the latest AMD Catalyst drivers especially if those where BETA drivers.

2.Revert back to stable mobility drivers. !!!

ALSO TO NOTE: Skyrim runs well on W10, as long you have updated your system with the older .NET Framework 2.0 and 3.5 runtime files.

W10 will tell you that, if you start skyrim executable the first time.

I actually tried everything you suggested (and more) when I had experienced that issue, but literally nothing worked, and it ended with the destruction of my Windows installation, but I'll keep that for future reference regardless. I have a hugehttp://www.tomshardware.com/answers/id-2735833/logonui-exe-application-error-windows.htmlon Tom's Hardware about the problem I had. Fortunately I have just created a Windows 10 recovery CD for such situations.

Oh, sorry to here about that. I hope Windows runs fine now.

...and a very clever move, to create a recovery disk. You never know, RIGHT ???

------------------

Also i have read the whole article, on that thread you posted. On laptops there is nothing special you can do within the BIOS. So i wouldn't mess with the BIOS anyway.

I such situations, it's more that advisable, to make backup disks from your current OS, before you attempt to install a new one.

Also, the best thing is - if you install a new OS, install it from scratch and not via update. (so make a bootable disk). Otherwise, many things can go wrong, as in your case.

However, doing that - be careful not to delete your native pre-installed OS partition that your laptop comes with. In this case Windows 8.1.

------------------

After that nightmare, I'm going to be a bit more diligent. While I still don't have a proper way to back up my files (like an external hard drive) and can't afford one, I will be creating a lot more system restore points, as one of my issues with the problem I had was that my one and only system restore point was corrupted. Don't ask why I didn't have anymore system restore points besides that one, it was probably intentionally working against me.

I created the Windows 10 recovery disk mainly because the recovery partition on my hard drive will restore the operating system to Windows 8. Not Windows 8.1, Windows 8. So, I needed one that would restore my system to Windows 10. Thinking maybe I should create a system image too.

Oh well, when I can finally afford to, I'll be purchasing my own "personal cloud" (basically just network attached storage using a RAID array).

Okay man. Take care...and my best wishes from now on. !!!

Interesting topic, was curious about skyrim & W10. Not that I'm in a hurry to update although the free upgrade for the next 12 months is mighty appealing... I'll have to check with my hardware vendors if my current rig can run this new OS without swapping hardware at least...

If your computer can run Windows 7 well, it'll run Windows 10 even better. For me, Skyrim's performance wasn't improved much at all because I don't believe there's DirectX 12 support for my hardware yet, but for more powerful hardware, there could be some noticeable differences.

Windows 10 System Requirements

• Processor:

  1 gigahertz (GHz) or faster processor or SoC

• RAM:

  1 gigabyte (GB) for 32-bit or 2 GB for 64-bit

• Hard disk space:

  16 GB for 32-bit OS 20 GB for 64-bit OS

• Graphics card:

  DirectX 9 or later with WDDM 1.0 driver

• Display:

  800x600

I can't imagine you PC can't meet those requirements.
