The same behaviour is occurring on machines running the 32-bit version of windows (mine included), so this is clearly not a problem exclusive to the 64-bit version. There *must* be something that everyone experiencing this problem has in common - be it a setting, specific software app (or type of software app), installation peculiarities, whatever.
I am running WinXP Pro Sp-2 with all latest updates on a Centrino notebook - 1.4Ghz, 1024MB Ram (PC2100), 80GB HD.
I also run (all latest builds/versions/releases):
Acronis TrueImage 9
GenieBackupManager Pro 6
GhostSecurity Suite RegDefend 2
AVG Pro 7.1
Webroot Spysweeper 4.5
Tenebril GhostSurf 2005 Platinum (includes SpyCatcher)
WinPatrol Plus 9.8
Admuncher
ZoneAlarms Pro (with anti-spyware active)
Executive Diskeeper 10
Webroot Window Washer 6
Directory Opus 8.2 Unicode
Sandboxie
CachemanXP
There's more but these are the apps that have the potential (I think) to block writes to the registry at startup... I am currently running WB5 with the SimpleAlpha skin. This after an initial reboot following uninstallation/reinstallation with SDC - I am running the latest beta build. I have a good feeling about this *taking* this time, but am not holding my breath. I'll know after a reboot but I can't bring myself to do it just yet as I am enjoying the skin
Actually, I've a reboot to do as RegDefend has just updated itself so we'll see...
Anyone who has made it through my partial list of apps and is experiencing this problem - do you see any commonality? FWIW I am also running Office 2003, GPSoftware's DOpus 8.2 unicode, and browse the web with the latest build of Maxthon.
Just to close (and more a note to self) I haven't adjusted my display settings this time around - they're at 16 bit which rules out per pixel blending - I'll see if this changes anything over the next couple of reboots (assuming this one is successful).
