HAL.DLL Missing or Corrupt

If you get an error regarding a missing or corrupt hal.dll file, it might simply be the BOOT.INI file on the root of the C: drive that is misconfigured

Insert and boot from your WindowsXP CD.
At the first R=Repair option, press the R key
Press the number that corresponds to the correct location for the installation of Windows you want to repair.
Typically this will be #1
Type bootcfg /list to show the current entries in the BOOT.INI file
Type bootcfg /rebuild to repair it
Take out the CD ROM and type exit

There are quite a few services you can disable from starting automatically.
This would be to speed up your boot time and free resources.
They are only suggestions so I suggestion you read the description of each one when you run Services
and that you turn them off one at a time.

Some possibilities are:

Setting Capslock, Numlock, Scroll Lock

If you want to set the startup state for any or all of these keys,
you just need to edit the registry.

Start Regedit
Go to HKEY_CURRENT_USER \ Control Panel \ Keyboard
Open InitialKeyboardIndicators
Change the value to one of the following numbers
0 - All Keys off
1 - Caps Lock on
2 - Num Lock on
4 - Scroll Lock on
For multiple keys, add their values:
3 - Caps Lock and Num Lock on
5 - Caps Lock and Scroll Lock on
6 - Num Lock and Scroll Lock on
7 - Caps Lock, Num Lock, and Scroll Lock on
Log off and back on again

Common Control Panel Applets

The follow are some common Control Panel Applets that are located in the \windows\system32 directory.
If you find yourself using any of these frequently, then you can simply make shortcuts to them on your desktop.

desk.cpl	Display Properties
firewall.cpl	Firewall Settings
inetcpl.cpl	Internet Options
mmsys.cpl	Sound and Audio

Viewing Installed Drivers

If you want to see a list of installed drivers, you can run the driverquery program
There are a lot of available switches to view different types of information.
On use can be to export to a CSV file for viewing in Excel
An example would then be:
Driverquery /v /fo csv > drivers.csv

Hiding Manage My Computer

If you want to remove Manage My Computer from My Computer

Start Regedit
Go to HKEY_CURRENT_USER / Software / Microsoft / Windows / CurrentVersion / Policies / Explorer
Create a DWORD value called NoManageMyComputerVerb
Set the value to 1
Reboot

To take ownership of that folder again:

Right click on the folder
