My problem i am having is that after i install deamon tools. My login screen changed to an old windows 98 type login screen. Just the plan on white box with a black screen instead of the newer one with fancy graphic. I am still able to login to my computer just fine. Second thing is that explorer.exe stops working. Wont load without me manually doing it. Third thing i get a few diffrent errors. The worst one is A Generic host 32 error. Other have been errors about windows blocking certain programs from runing. like explorer.exe and winlogon.exe. Which then cuases my system to crash and restart. I have tried reinstall windows and install after all the windows updates and still get the same similair errors. I recently tried install powerISO and got the following errors. After getting around all the errors my deamon tools doesnt seem to work. Usually get an access denied type error.

Hanging application PowerISO.exe, version, hang module hungapp, version, hang address 0x00000000.
