Large & extra large icons blank

First post here on the SevenForums! I'm only saving the tough ones for you guys! Here's the problem:

My client's computer was infected with a virus obtained via Facebook. I removed this and multiple other infections (and I'm pretty thorough with my scanning). She gets it back, starts working on it, and apparently her devices and printers icons are blank. Not missing, like with a "blank page" icon, just... blank. Here's the kicker: it only happens with large and extra large icons. It also happens with normal folder icons. When I change it to medium or lower, they come back. I've tried rebuilding the icon cache database several times, tried sfc /scannow, tried chkdsk, tried uninstalling any recent updates, etc... There have been no hardware changes, the hard drive has been tested as good (no bad sectors), her dual monitors are at a sane resolution, and I'm confident that the viruses has been removed. Trust me -- I've tried all the obvious stuff I can think of. Thanks and Good luck!

Edit: Also, I did about 30 minutes of searching through previous threads. Couldn't find a thing, but I could have missed it...

Well you probably pulled some icon cache files off that were infected but also had the L and XL icons. If sfc didnt work you could try a repair install. It will re-install only the files with different hash marks.

Make a backup and restore point first just in case

Not a fan of the system restore... I've often seen it cause more problems than it solves...
What repair install do you speak of? Vista and 7 repair options suck compared to the repair options I had in XP. You know, the second repair option when booting to an install disc? Gone in Vista and 7. I vaguely remember another repair procedure in 7, but it basically rips out your programs while keeping your docs, and that's not what I wanna do here. And startup repair sucks. But I digress-- can you post the repair instructions anyways in case there was something I missed? Thanks for the quick response.

Thanks A Guy. I'll give it a try when the client isn't using her computer. I'll let ya'll know what transpires. BTW, I like that signature.

Finally got a chance to try A Guy's instructions. Worked perfectly! Thanks, A Guy!

I know this is an old thread but I had a very similar experience to this thread and solved this issue for my computer and thought others may benefit.

After doing tons of google searching and trying everything I could find I was going to repair install windows 7 because nothing worked. Not system file checker, not resetting icon/thumbnail caches, not scan drives for issues, nothing.

But then the answer came to me... I remembered that I removed registry settings when cleaning up Linkey garbage and found 2 that I shouldn't have removed. Thankfully I backed up those keys before deleting them. Once I merged them back in, the large and extra large thumbnails showed up again. For those who may have this problem here are the keys I accidently removed.

First one was
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows]
"IconServiceLib"="IconCodecService.dll"
"DdeSendTimeout"=dword:00000000
"DesktopHeapLogging"=dword:00000001
"GDIProcessHandleQuota"=dword:00002710
"ShutdownWarningDialogTimeout"=dword:ffffffff
"USERNestedWindowLimit"=dword:00000032
"USERPostMessageLimit"=dword:00002710
"USERProcessHandleQuota"=dword:00002710
@="mnmsrvc"
"DeviceNotSelectedTimeout"="15"
"Spooler"="yes"
"TransmissionRetryTimeout"="90"


And the 2nd one was...


[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows]
"IconServiceLib"="IconCodecService.dll"
"DdeSendTimeout"=dword:00000000
"DesktopHeapLogging"=dword:00000001
"GDIProcessHandleQuota"=dword:00002710
"ShutdownWarningDialogTimeout"=dword:ffffffff
"USERNestedWindowLimit"=dword:00000032
"USERPostMessageLimit"=dword:00002710
"USERProcessHandleQuota"=dword:00002710
@="mnmsrvc"
"DeviceNotSelectedTimeout"="15"
"Spooler"="yes"
"TransmissionRetryTimeout"="90"



These two keys almost identical. I orginally removed them due to this setting below that was with them. I should have just removed this info.


"LoadAppInit_DLLs"=dword:00000001
"AppInit_DLLs"="C:\\PROGRA~3\\Wincert\\WIN64C~1.DLL C:\\PROGRA~2\\Linkey\\IEEXTE~1\\iedll64.dll
C:\\PROGRA~2\\SETTIN~1\\systemk\\x64\\syskldr.dll "


Oh well, it now works like its supposed too and large and extra large thumbnails are working again.

Hi coffeewow, how did you merge the files, my system on has 2 lines under the registry items you mentioned.
Any help you can offer would be appreciated.

You shouldn't need to merge the files unless you already deleted the whole thing. Just delete the bottom 2 lines.

You should probably google merging registry keys though and do some reasearch on the process because you can really hose up your computer if you dont know what your doing. I dont know your background though. So just sayin...

Basically to merge you just copy those keys into notepad and change the file to a .reg and windows will ask you if you want to merge it when you double click on the file. You'd also need the windows registry header on there too. Im not on a computer atm or I'd post that for ya. It can be googled as well though.
