Disable the useless Security Center warnings

If your Windows is not provided with one of the well known virus scan and/or firewall software, the Security Center will come with useless repeating reminders. The reminders can be disabled by changing the values AntiVirusDisableNotify and FirewallDisableNotify to the DWORD-value 1 in the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center

Remove the low disk space warning

Probably you have seen the irritating 'low on disk space'-warning before, if your hard disk reaches full capacity. This warning message can be turned off by adding the DWORD-value NoLowDiskSpaceChecks with value 1 in the following key:
HKEY_CURRENT_USER\Software\MicroSoft\ Windows\CurrentVersion\Policies\Explorer

Optimizing Windows Search

Within Windows XP you are able to search your computer for files (Start, Search), but takes some clicking to get what you want! To optimize the search function, you have to make some registry changes. To make changes, navigate to the following key:
HKEY_CURRENT_USER\Software\ Microsoft\Windows\CurrentVersion\Explorer
where you will find some important DWORD-values. Change these values to optimize your Windows search:
SearchSystemDirs=1
SearchHidden=1
IncludeSubFolders=1
CaseSensitive=0
SearchSlowFiles=1 (if you have a tape drive, else: 0)

fast Windows shutdown

When Shutting down, Windows can take a long time. You can speed this up (at your own risk) with the following tweaks in the registry key:
HKEY_CURRENT_USER\Control Panel\Desktop
Change the following String values:
AutoEndTasks=1
HungAppTimeout=4000
WaitToKillAppTimeout=4000
WaitToKillServiceTimeout=4000
(the last registry value is also present in HKLM\SYSTEM\CurrentControlSet\Control)
