Hello, i have an HP probook 8440p laptop with windows 7 32 bit. the system doesn't want to start because of this error : LogonUI.exe impossible to start the programm, comctl32.dll is missing.... so i'm stuck with a black background and my mouse pointer. i tried F8 with all the possible things in the menu : Safe mode = same problem Repair = no problem found Repair with restore point = impossible because something is corrupted...i tried 4 restore points and each time it says after a few minutes that the operation is cancelled because of a corupted file... shell prompt = black background So i removed the drive and put it on another PC and i did a full check with Bitdefender endpoint security : no virus found. i did a Chkdsk, it found some problems and fixed them. I found another PC with win 7 32bit and copied the LogonUI.exe + comctl32.dll files in c:\windows\system32\ folder and i replaced the Disk in the laptop but the problem is still the same... I realy don't want to reformat, anyone has a suggestion ? Thank you for your help
Thank you for your help but... 1. Start Windows 7, and log on to an administrator account. i can't do that...
Hey, Did this perhaps happen since today ? Today at the end of the day, we received 5 systems pretty much within the hour, Not all details are known but all systems do suddenly have corrupted windows, 3 of them backscreen with mouse, 2 other's got different files corrupted. On one i was able to do a system restore, but still kept different applications corrupted though windows worked it kept hanging, Even a laptop we got for simple checking, after windows update it got the same issue. chkdsk did find issues on the pc btw, but it did not solve it. So i am guessing windows rolled out a update that started to corrupt "random" not sure files. Tomorrow i have a early start at checking the systems, if i find the cause and or solution i will post it. Btw, do you perhaps have panda cloud ? or any panda software installed ?

yes it happened today in the afernoon, but the antivirus is bitdefender endpoint security. I already tried teh startup repair, it doesn't find any problem..
OK one last try for me and if this does not work then all I can see is a complete reformat. Now I just tried this on my computer, but this will only work if you can boot into safe mode. >Boot into safe mode >Open My Computer >Pop in your win7 disc >When you see it loaded in your drive >Right click on it and select to run it >It will load up and you can follow the Repair Install procedure. Step 8 Now that is as far as I got and did not continue because there is nothing wrong on my computer. I don't know if this will work the same as a live repair and not remove any programs or things you have, but if your dead in the water it can't hurt. Your call.
unfortunately i can't boot into safe mode, i just get the the window with the error message with a black background. it's impossible to access to an icon, safe boot or not...
Well I'm at a loss then?? I'm no computer expert here but it sounds more like there is more than just a missing file to me. You can wait and see if someone else chimes in or do a full format.
the problem is that the file is present because i copied it from another PC, unless it is using it from another folder than : c:\windows\system32\ the file should be here and correct
