I’m getting the Windows 8.1 explorer.exe “Unknown: Hard Error”. Basically, when I boot into normal mode, explorer.exe crashes instantly and failts to restart. This leaves me with a blank screen in which I can open task manager(ctrl+shift+esc), but cannot run explorer.exe again. The MBAM scan came back clean, and so did the avast! scan. I’ve run sfc.exe, which found no integrity errors. I’ve also run dism.exe, which gave me “Error: 0x800f0906” as well as stating that the source files could not be downloaded. FRST was run in safe mode, as this was the only way possible for me to produce logs. If I can boot into normal mode without explorer.exe crashing, I will upload those logs. Thank you. ;D
Eddy’s link is a good one as there is no apparent malware
Thank you for quick response. I ran chkdsk in normal mode, but it found no errors. I just ran it in safe mode, and it said the drive must be repaired. I’m hoping for the best, thanks! ;D
I fixed it to the best of my abilities. Now, I no longer get the error, but at boot explorer.exe does sometimes crash; however, it reloads within seconds. I thought I had fixed it, but nothing loads at startup besides unchecky, MBAM, and Geforce Experience. I tried to run a scan with MBAM which told me that the rootkit drivers failed to load, and this quite possibly could be caused by rootkit activity. I’m uploading FRST which I thankfully was able to run in normal mode.
Might be worth running SFC next, I see you have windows all in one so you can use that to do it

Thank you once again, essexboy. Sadly, I reformatted and reinstalled before I saw this post. Although, a couple days after the reformat and reinstall of Windows, I’m getting some detections from my antivirus and antimalware programs. I’d appreciate if you’d provide your help on that topic. I’m also very sorry for wasting your time with this topic. Have a good day.
