How to Repair Windows Registry Errors



Windows Registry is a group of data files within the Windows Operating System that contain essential information for running Windows on a computer. Windows Registry runs all programs, user interfaces, and services that the Windows Operating System provides and is critical to a computer’s proper performance. Whenever a program is installed on a computer, Windows Installer places data in the Windows Registry to allow the program to run and access other Windows Operating System components. When these data files are lost, corrupted, or incomplete uninstallations or viruses modify them, the computer may not work properly or experience decreased performance. By using a software known as a registry cleaner, a user can repair the Windows Registry and improve his/her computer’s performance.

Free Window Registry Repair

Free Window Registry Repair is a free registry cleaner that allows users to repair Windows Registry by removing invalid registry entries, deleting registry file copies, and replacing missing registry files. Free Window Registry Repair also saves the current registry settings before making changes to Windows Registry so that the user can restore his/her computer if anything goes wrong.

CCleaner

CCleaner from Piriform is a free and highly popular registry cleaner that increases a computer’s speed and performance by removing unwanted files from Windows Registry. CCleaner, like Free Window Registry Repair and most other registry cleaners, also restores missing registry files and files that viruses or invalid information have corrupted. CCleaner also deletes the user’s browser history, temporary Internet files, and cookies that have been saved to the computer upon visiting websites or entering personally identifiable information.

Advanced System Care
Advanced System Care is possibly the most advanced registry cleaner available and is completely free.

Advanced System Care defragments the computer, deletes personally identifiable information from the browser, and includes a comprehensive anti-virus software that runs fast scans and finds virtually any virus on the computer. Advanced System Care also includes a real time anti-virus shield that prevents malicious software from running or accessing Windows Registry.

HOW TO EDIT THE BCD REGISTRY FILE

Image
The BCD registry file controls which operating system installation starts and how long the boot manager waits before starting Windows. Basically, it’s like the Boot.ini file in earlier versions of Windows. If you need to edit it, the easiest way is to use the Startup And Recovery tool from within Vista. Just follow these steps: 1. Click Start. Right-click Computer, and then click Properties. 2. Click Advanced System Settings. 3. On the Advanced tab, under Startup and Recovery, click Settings. 4. Click the Default Operating System list, and edit other startup settings. Then, click OK. Same as Windows XP, right? But you’re probably not here because you couldn’t find that dialog box. You’re probably here because Windows Vista won’t start. In that case, you shouldn’t even worry about editing the BCD. Just run Startup Repair, and let the tool do what it’s supposed to. If you’re an advanced user, like an IT guy, you might want to edit the BCD file yourself. You can do this

DNS Scavenging.

                        DNS Scavenging is a great answer to a problem that has been nagging everyone since RFC 2136 came out way back in 1997.  Despite many clever methods of ensuring that clients and DHCP servers that perform dynamic updates clean up after themselves sometimes DNS can get messy.  Remember that old test server that you built two years ago that caught fire before it could be used?  Probably not.  DNS still remembers it though.  There are two big issues with DNS scavenging that seem to come up a lot: "I'm hitting this 'scavenge now' button like a snare drum and nothing is happening.  Why?" or "I woke up this morning, my DNS zones are nearly empty and Active Directory is sitting in a corner rocking back and forth crying.  What happened?" This post should help us figure out when the first issue will happen and completely avoid the second.  We'll go through how scavenging is setup then I'll give you my best practices.  Scavenging s
