Windows explorer not refreshing icons/ thumbnails

qorda · Jun 4, 2013

Hi All
Today I uninstalled opera and IObit malware fighter. The uninstaller deleted relevant registry entries.
Since then I am having problem that if I change the disc in my DVD drive, the icon/name for new disc do not show up in the explorer but instead the name and contents of the previous disc continue to show.
I have Win XP SP3 with all updates since. F5 doesn't refresh and System restore didn't help.
Tow scans by different antiviruses all clear.
I have to reboot the computer to view new DVD disc contents in explorer. Even then explorer after displaying new thumbnails comes up with error= referenced memory not read.
Obviously explorer registry entries are corrupted. Unfortunately no back up.
What can I do?

what do you have in this registry key ?
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\DriveIcons\P
- instead of the P, look at your own DVD drive letter.

Thanks,
There seems to be no entry in registry's "Explorer" subfolder of the above path for "driveIcons".
In the mean time I have cleaned the lens of DVD drive to no effect and also uninstalled and re-installed the DVD drive from device manager; no good!!!
In explorer DVD Ram Drive shows correctly as drive G, but on insertion of a DVD disc it would not change to the name of DVD. Although when I click on the icon the correct folders in the disc are displayed.
Rest of the issue is listed in my main question that changing the disc would not refresh explorer unless I reboot. Also clicking on SOME of the contents of dvd disc would bring up explorer.exe error, memory referenced at ------- etc could not be read.
I know memory is fine and I have not opened the case of my PC, wires and connections are secure and in past such problem was resolved with re-installation of windows that I wish to avoid. No change of memory modules was ever needed.
Thanks for the help.
BTW is there a tool to restore XP registry back to original by repairing the damaged entries?
Thanks for the help

I've had this before when uninstalling malware apps. The registry Driveicons info is deleted or screwed - in your case some entries seem to have been deleted.
Substitute the P below by your DVD drive letter and merge the reg entries.
Let us know what shows up in Windows Explorer a) with no DVD in the drive and b) a DVD
in the drive (Backup the registry beforehand)

REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\DriveIcons\P]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\DriveIcons\P\DefaultLabel]
@="DVD"

Did a successful registry alteration as you suggested. The out come is just that previously explorer showed drive G as "DVD Ram" and now it is "DVD".
All the problems are still there: no recognition of DVD title on insertion of disc, no change in explorer of title or contents on changing the disc unless I reboot, and same error message on opening explorer by clicking to display contents on inserted DVD.
I have now even refreshed XP on the current installation in the hope that it would correct the error but absolute failure.

Ok All sorted. Spent two days doing all kind of software maneuvers trying to sort it but in the end it was a 5 minutes job thanks to Uwe-Sieber, God bless him and Google.
He had commented at another site that mess with registry can turn off notification to the system to refresh when disc is changed. His auto-run tool http://www.uwe-sieber.de/drivetools_e.html did the miracle in a second and all is fine that repair install failed to do because that did not change the existing settings!!!
