Fix Registry to Customize Windows

You may customize windows appearance or setting, such as the color of frame, hidden icon, animation effect. So if your system is changed by some scripts that are embedded in web pages, you can fix the registry errors indeed. Of course you need to know some registry skills. Now I will share my knowledge with you.

A – To change the tips of my computer icon. You will get some tips when you move mouse to my computer icon. For example, ‘show files or folders in your computer’ or ‘my lord welcome’. And this type of greeting is also shown in the left panel of explorer. So you may edit this sentence by registry. I suppose you may open Regedit.exe. You may search this entry HKEY_CLASSES_ROOT – CLSID in it and then find the key 20D04FE0-3AEA-1069-A2D8-08002B309D. You click this key and right click key ‘Info Tip’ in the right panel. Here you may input any greeting you want. I think you should restart system after that.

B – To rename the icon of my computer in desktop. You need to find the key 20D04FE0-3AEA-1069-A2D8-08002B30309D. You need to change the value of key ‘LocalizeString’ and then flash desktop.

C – To find the hidden recycle bin or my documents. Sometimes you delete the recycle bin by mistake. Or it is hidden by scripts. Take it easy, you may get it back. You need to find the entry HKEY_LOCAL_MACHINE – SOFTWARE – MICROSOFT – WINDOWS – Current Version – Explorer – Desktop – Name Space in registry. You may create new key under this entry. If you want recycle bin, you create the key 645FF040-5081-101B-9F08-00AA002F954E. The key 450d8fba-ad25-11d0-98a8-0800361b1103 is for the icon of my documents.

You may do a lot of customized settings for your system by registry. You may also restore some wrongful operations in opposite ways. But it is always boring to modify registry manually.

Windows XP Registry Repair

The Windows registry on your PC is a set of files which store all the essential settings for hardware, the operating system, the control panel, application software, user preferences and user profiles, and file associations (which programs run which types of files).

How is Windows XP registry repair done, and why does the Windows registry ever need to be repaired anyway? At the bottom of this article, there is a link to a resource page which gives access to software tools you can use to repair the registry.

Repairing or cleaning the registry can also be done manually, using the program regedit.exe (Registry Editor), which comes with Windows XP, or with reg.exe from the command line. Manual editing is not recommended though, even if you do a backup, because the registry files are absolutely essential for the Windows operating system to run, and it is all too easy to damage them by careless editing. Microsoft Support itself says this – ‘Although you can use Registry Editor to inspect and modify the registry, doing so is not recommended, as making incorrect changes can damage your system.’

If you do damage the registry during manual editing, and your backup does not work either, the only other solution is a reinstallation of Windows XP. You want to avoid this scenario if you can.

So, the use of special software for Windows XP registry repair is recommended (see below). What about the reasons for repairing the registry – why would it be necessary?

The reasons you would want to repair or clean the registry are many and varied. A damaged registry can make a Windows XP machine run erratically, or not boot up at all. After some time has passed since you first got your PC, entries in the registry for old or uninstalled software will remain, making the system boot up slowly, run more slowly and affecting the stability of the whole system – have you had a recent freeze, or have you seen the Windows ‘blue screen of death’ recently? As time goes on, the registry grows in size, often far beyond what is necessary. You may also have many duplicate entries in the Windows registry, degrading system performance. You may also need to restore the previous settings in the registry if the installation of a new hardware driver has made your system unstable.

The good news is that there are many software tools available now which will make repair of the registry fast and painless. Most of them will let you do a free scan of your system, to see if there are any problems. Such tools are called registry cleaners or registry repairers, and are very easy to install and use, and may well make a dramatic improvement in your computer’s performance.

Windows XP Registry Files Revealed – Structure And Location

In every computer, the registry is saved in separate files in the windows directory. The Windows XP registry files are located in the %systemroot%/system32/config directory where %systemroot% is usually WINDOWS or WINNT. Within the Windows XP registry files are the structure of the hives and corresponding location of each hive. This article will help you understand how the Windows XP registry files correspond with the hierarchial structure.

In the registry, there are hives that correspond to several files. Hives are a collection of keys, subkeys and values that contain the configurations for the operating system and programs. In the registry, there are 5 groups: HKEY_CLASSES_ROOT(HKCR), HKEY_CURRENT_USER(HKCU), HKEY_LOCAL_MACHINE(HKLM), HKEY_USERS(HKU), and HKEY_CURRENT_CONFIG(HKCC).

For the corresponding hives, you will see several types of extensions: no extension, .alt, .log, and .sav.

No Extension: The complete registry hive

.alt: An alternate copy of the registry hive

.log: A log of changes that have occurred within the registry hive

.sav: This is an automatic backup created from when a setup or program installation occurs.

Here are the corresponding files:

HKCC: System, System.alt, System.log, System.sav

HKCU: Ntuser.dat, Ntuser.dat.log

HKLMSAM: Sam, Sam.log, Sam.sav

HKLMSecurity: Security, Security.log, Security.sav

HKLMSoftware: Software, Software.log, Software.sav

HKLMSystem: System, System.alt, System.log, System.sav

HKU.DEFAULT: Default, Default.log, Default.sav

Another thing to mention is that there is a “repair” copy just in case your registry gets corrupted. These files are located in the %systemroot%/repair directory. These usually will come in handy when you get bootup errors and need a find a clean copy of the registry. One way to fix this problem is to use the Windows CD to get into the recovery console. From there, you would be able to copy the registry files from the “repair” folder to the system32/config directory.

So you can see the logic behind the registry editor with the structure and location of the Windows XP registry files. By knowing this information, you can understand how a registry works with the operating system. These files can get corrupted just like any other files and knowing where they are located can help in troubleshooting many issues in the future. The Windows XP registry files are very delicate to work with, so make sure that you are taking absolute care when manipulating these files.
