Windows® XP Registry Help
Microsoft® released two editions of Windows® XP operating system in the market - Windows® XP Home Edition and the Windows® XP Professional Edition. Both the editions require the same underlying hardware to run them. They both work as 32-bit operating system thus supporting only one microprocessor. The Windows® XP Professional Edition has greater security features than the Windows® XP Home Edition. It includes facilities like IIS, EFS, hosting, TCP/IP protocol techniques, SAP Agent, etc. The Windows® XP registry is an important part of the Windows® XP operating system. It can be used to control the operating system as well as fix the problems that occur in the operating system.
Here is a description of the issues related to the Registry for which iYogi provides remote tech-support:
- Accessing Data
- Support for Invalid or Missing Keys in the Registry
- Support for Issues due to Frequent Change of Programs/ drivers
There are two major files in the Windows® system directory. They are 'system.dat' and 'user.dat'. All the information regarding the computer hardware is stored in the 'system.dat', and the data regarding the user is stored in the 'user.dat' file. The Windows® Registry is used as a database. It is used for the storage of information of various programs as well as privileges. The registry is used to store the settings and other values of the operating system. It is important to save the contents of the registry before any modification is made upon it. The registry can be accessed directly from the 'Start' menu by going through run. By entering “regedit” in run, the system would open up the registry editor from where you can access the registry data.
Support for Invalid or Missing Keys in the Registry
The users can come across various computer problems because of registry issues, this may happen because of the invalid or missing key during or after registration. It may result in crashing or freezing of the computer. The computer can become generally slower. The backing up and restoring of the Windows® registry is important, the system by itself would create and backup registry points over periods of time. We can access and revert the system back to an older date by the System Restore function. This can be found in the 'Accessories' and 'System Tools'.
The frequent change of programs or removal of the programs from the startup can cause the occurrence of registry errors. The change of hardware drivers can lead to error in the system if the previously installed hardware is not removed from the system. The software that is removed from the system must be properly uninstalled and not deleted, or it may cause a conflict in the registry. Spyware can be installed into the system to prevent external malware from coming into contact with these files. Any manual change into the registry files can cause serious error to the system. Editing the registry is not advised and proper back up point must be made before it is done.
