Hey guys, I have been using Vista for almost a year now and did not come across any problem. Just few days back, my system failed to load the Vista welcome screen. After that, I got the following error:

“An unauthorized change was made to Windows.

Error: 0xC004D401

Description:

The security processor reported a system file mismatch error.”

Hi experts,

I have just successfully installed Windows 7 on my PC. Everything seems okay with all other programs and applications but when I try to turn on Virus Protection, I am getting an error dialog which is shown as under:

This program will not run.

Security Center did not trust this program because its identity can’t be verified.

Can someone give me a suggestion what I need to do to resolve the issue?

Thanks.

There is a problem in my Inbox Server Xeon 2.33 GH with raid-1 configured. The server is unable to boot and shows error message,"NTDLR is missing" when I start my system with bootable Windows 2003 CD.  The said system boot's success from hard disk.

My operating system is windows XP.

I think its best operating system for me.

But sometimes I find some error in the windows.

A few days ago, I used windows task manager by pressing Ctrl+Alt+Delete.

But today I can not find task manager.

A error message is coming which tells "Task manager has been disabled by your administrator".

Only I use this computer.

So why this type error message is showing.

I am using windows 2000 operating system. I am using broadband internet by LAN. But now my connection can not be established. An error message is showing on my screen. It tells "Link to connection failed. Reconnect pending. If you continue to receive error,you can enable logging for analysis". I want to know what is the exact cause of this problem. How can I establish my connection and avoid this message?

Hello there,

We have a server running OCS 2007 R2. It has been working fine for a number of weeks but last friday we had to rebooted and since them all clients that are running Windows 7 are getting a red exclamation client on the OCS icon and the following error " Cannot synchronize with the corporate address book. This might be because the proxy server setting in your web browser does not allow access to the address book.

If the problem persist, contact your system administrator". Windows XP clients are not affected.

Can I downgraded my laptop from Microsoft Windows Vista or Windows 7 to XP? and where I can find drivers for the hardware devices for my laptop?

Can this said hardware harm my laptop?

Hi,

I have a problem about my PC. Every time I resume it from its sleep mode, I don't see a thing in my screen/monitor. All I see is a black screen, but it is not turned off and i don't hear any beeps either. How should I fix it? By the way, I'm using Windows 7 Ultimate Version.
