I had a virus problem , and that probably deleted keys and values associated with several xp services.
Will a repair install (in-place upgrade) of xp reinstall these services ?
Or i need to reinstall XP (with format) , or maybe install sp2 ( i use sp1 ) ?

Thanks.
Luiz.

Hello garmanma.
I donīt know if sfc /scannow will be much effective in my case, as my dllcache folder is almost empty.

Thanks.

If SFC.EXE isn't able to find what it needs on your hard drive, then it'll prompt you for your installation disk for the replacement files.

Then, i should try:

1 sfc /scannow (for the sake of missig or corrupted system files )
2 repair install

If none of this recreate the missing critical system services , a reinstallation without format.

And get SP2 ASAP. This is for your security, and also MS will not give you updates without it as they no longer support just SP1.

To set your services to the default values, you can visit http://www.blackviper.com for registry reset files

Usasma , the site you indicated is great.
But iīm still going to update to sp2. The services are missing on a system with sp1 .
And the site only has info backwards until sp2.
Do you know of any other site like that that could possibly have similar content for sp1 ?

Thanks,
Leza.

SP2 is a gigantic update for XP and is considered a requirement in most places. It improves performance, stability, and security. The only 2 problems with installing it are:
1) If you're infected with malware
2) If you haven't updated your drivers and they aren't compatible with SP2

Both are easy to fix, so I'd suggest installing SP2 - it'll reset most of the services on it's own, so there'll be less for you to do.

In http://www.blackviper.com , there is only recommendations on the start value of services. For sure a sp2 installation will reset these values.
But, as i said in the original msg. of this Topic, i need to know how to "recreate" the xp services. How to revert all the xp services to their default configurations .
Making the:
- keys
- subkeys
- values names
- values settings
For each xp service.
Return to their original settings. Recreating subkeys and values.

A repair install do this ?
Or a upgrade to sp2 ?
Or only a complete reinstall ?

What i donīt know for sure is if there is something else wrong in addition to the services problem.
Thatīs why iīm afraid of applying sp2 ( in a system in a non healty condition) , not doing before a repair install.

Thanks
Leza.

FWIW - you shouldn't be messing around in the registry trying to start/modify services. One small error in any one of the many different keys there could render your system unusable.

Also, there's several hundred (if not more) sub-keys to the Services key at HKLM\System\CurrentControlSet - this is a daunting task and one that I don't feel capable of handling (and that's not the only part of the registry that deals with services).

First I would try and ensure that all viruses were removed from the system. Even if you get a repair install to work, if the system is infected you may not get the results that you desire. Once the system is virus free, then a repair install will reset those values in the registry.

The easiest way to remove viruses from that drive is to slave it to another computer (with a good, up to date antivirus program) and scan the drive to remove the viruses.

About virus , i received a "OK , your system is clean, you can install sp2 now" from an analyst in a hijack log analisys forum.
I wasnīt thinking in repairing the services in the registry manually , but just explaining that the services where realy almost fully deleted from there.
Good to know that a repair install is going to reconstruct that all.

Thanks
Leza.
