Since my computer scans clean of malware, I'm wondering if this is a W2K reconfiguration issue now.
I'm running Windows 2000 on a laptop which I use with a wireless hub at home, then bring to the office to connect to an ISP/LAN which browses via a DSL.
I recently cleaned out some viruses and Trojans, and now find my desktop wallpaper locked up with desktops icons against a black background. (Wallpaper is visible during boot-up, but once the desktop icons appear, the desktop goes black). Certain other changes have taken place as well - such as the removal of my PopUpCop toolbar button, and toolbar lockup - upon reinstall of PopUpCop, I'm not allowed to have it add its toolbar button.
My post clean-up scans are running clean, so I'm wondering if I was a little too zealous in deleting files and screwed up my registry targets.
Recent experience with a disabled Task Manager has taught me malware can lock features. As a result, I've become familiar with registry settings such as NoChangingWallpaper. It seems to be in normal (not disabled) setting:
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\ActiveDesktop\NoChangingWallpaper = 0
However, when I click Start/Settings/Control Panel/Display/Background, I'm unable to activate any choices, and wallpaper is locked to an IE icon with the word "desktop". Elsewhere in these forums I've read about "desktop.html"
and in fact found the following registry setting:
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System Wallpaper REG_SZ C:\WINDOWS\desktop.html
... although there is no such file "desktop.html" on the machine.
So I'm wondering - if this System Wallpaper setting is the source of the wallpaper lockup, what should this entry actually read? Are there other wallpaper settings elsewhere in the registry I should check? And what about registry settings that have locked the toolbar from adding buttons?
Unfortunately, I have no pre-cleanup backups. Is there a way to reacquire the original W2K install defaults for desktop and toolbar permissions?
