Registry problems

As far as I know win2k rebuilds the registry each time it starts.

When I fisrt installed the win2k on my machine I've got some problems with some PCI device drivers and I made some modifications manually on the registry (including the PCI itens).

I resolved that problems with the driver, but now each time the computer starts the system finds a new hardware. I've to restart the computer in order to have the rigth configuration.

How can I repair the registry to avoid installing all the software again?

Thank you for your help.

Actually it does not.  It does make a copy of parts of the registry at each successful boot so that you can revert to the last known good configuration though.

If Windows is finding new devices on boot you need to either:

1) Install the driver for the device

_or_

2) Disable the device.

Otherwise, Windows will "find" the device at every boot.  This is not a registry issue but is part of the Plug-and-Play operation.

There is a known issue that with some (most) system BIOSes, the setting "Plug-N-Play OS" or "Use Plug-N-Play" (or some variation on this) should be set to NO or DISABLED.  On some systems it may say something about resource assignment and offer options of "Plug-N-Play OS" or "BIOS"/"System"/whatever.  Choose the one that isn't Plug-N-Play.  This fixes a remarkable number of device problems.

I didn't know that I had this question unlocked. I don't remember about the details how I resolved that problem, but I know that I had to install the operating system again.

However, Jhance helped me in the right approach.
