When you say you "can't run regedit and things like that", do you mean things like msconfig, cmd, etc.?
IF so then it sounds like something has borked your system files. First, if you're not running SP2 then go to Windows Update and install all available updates, this may fix the problem. If not then you may want to try running a repair installation of XP.
Boot from your Windows XP disc, at the first option hit "Enter" to install WIndows XP (not the "R" option), then hit "F8" to accept liscense agreement, then choose the repair option and follow the onscreen prompts during the install phase.
When it comes back up, try running regedit, msconfig, etc. If they work then go ahead and run Windows update until you're fully updated again.
Here is my issue--I hope someone knows the answer.
I run winXP home, 1.7 ghtz, 60gb hd, 256ram.
This is what happens every time I boot up:
First box that appears, in the top border it reads:
16 bit Windows Subsystem
Then in the box it is written:
C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose ?Close? to terminate the application.
Then two buttons below; ?Close? and ?Ignore?.
Then after a few minutes another box appears, in the top border:
In the box it reads:
MONITOR: Can?t find agent ?Bitware NT Agent? class ?WCN tAgent?
I did have old writing software installed. It started to malfunction so I uninstalled it. I think that was when this started to occur. Computer works fine, but I can?t run regedit and things like that.
Is there anything I can do about this?
