Q. When you attempt to start Windows XP, you receive a 0x800705aa error, a 0x80070002 error, a 0x80004005 error, a 0x800405aa error, and a 0x80090019 error?

The subject errors are generally caused by problems in third-party software, like WinTools.

01. Unplug the network cable from your Windows XP computer.

02. Remove the WinTools software from Control Panel / Add or Remove Programs.

03. Shutdown and restart your computer. During the initial startup, press F8 and start Windows XP in Safe mode.

04. Open a CMD.EXE window.

05. Type the following commands, pressing Enter after each line:

REG DELETE HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run /V WinTools /F
REG DELETE HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\\{87766247-311C-43B4-8499-3D5FEC94A183\} /F
REG DELETE HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\BrowserHelperObjects\\{87766247-311C-43B4-8499-3D5FEC94A183\} /F
6. Shutdown and restart Windows XP.

06. Open a CMD.EXE window.

07. Type the following commands, pressing Enter after each line:

CD /D "%ProgramFiles%\Common files\WinTools"
del /F /Q WToolsA.exe
del /F /Q WSup.exe
del /F /Q WToolsS.exe

08. Clean up the hosts file located at %SystemRoot%\System32\Drivers\Etc\Hosts.

09. Delete all the files that have Wtools or Wsup in their name, from %SystemRoot% and all the %SystemRoot% sub-folders.
