There is a registry edit to enable the Task Manager. The same step applies to Windows 2000 and Windows XP.
Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Windows\CurrentVersion\Policies\System
Name: DisableTaskMgr
Type: REG_DWORD
Value: 1=Enablethis key, that is DISABLE TaskManager
Value: 0=Disablethis key, that is Don't Disable, Enable TaskManager
The TaskManager can also be enabled using Group Policy Editor (only available in XP Pro/Vista Pro and up and if you're logged in as administrator).
1. Click Start
2. Click Run
3. Enter gpedit.msc in the Open box and click OK
By default Windows 7 does NOT include an email client. Users must choose a client to use. Microsoft suggests Windows Live Mail (which is a substandard replacement for Windows Mail).
