Windows 7: TrustedInstaller deleted

TrustedInstaller deleted

My problem is:
After having problems with TrustedInstaller I deleted it completely from my services-list. I didn't know that it is necessary to install Windows-Updates, so I can't update it now, but worse than that is that I can't activate my Windows Firewall or Windows Defender! It's very important for me to get help!!!

Hope you have some ideas to fix that

Thanks in advance.

Hello Bertie, and welcome to Seven Forums.

You might see if restoring the Windows Modules Installer (aka: TrustedInstaller) service using the tutorial below may be able to restore it for you.

Services - Restore Default Services in Windows 7

If that doesn't help, then you could do a system restore using a restore point dated before you deleted the service to restore it.

Exactly how was it deleted from services? It might be disabled but how was it deleted?

It's some time ago, don't know how I exactly deleted it. I can just say that it isn't in my services-list anymore, but it is in Computer -> Boot (C -> Windows -> services. So it might be that I've just disabled it.
If I had to say how exactly, I think I went to a file, went to the owners and deleted it there. If that is even possible.

Thanks for replying

If you meant "TrustedInstaller" for permissions and owner instead, then this below should help.

I looked up and found TrustedInstaller (see file). Maybe my problems are not TrustedInstallers fault:

-I can't activate Windows Firewall (0x80070424)
-I can't activate Windows Defender (0x80070424)
-I can't look for Windows Updates
If I try to install the Update I downloaded from the internet, again it's 0x80070424.

I hope you know or have ideas what the problem could be and how to solve it.

Thanks Brink

Well, the problem is not the files, but Windows Defender, Firewall and Updates. I can't remember that I've edited these.
I'm thinking about a reparation with the Windows 7 CD from my neighbour. Do you know if that could help and if yes, does that delete any of my files?

Thanks Shawn, think that's spelled right

If you have a restore point available dated before this issue, you could do a system restore with it to undo and fix this.

It all depends on if your neighbor's installation DVD is the same edition as what your product key is for. If it is, then you could do a clean install with it. If not, then you won't be able to. Be sure to backup anything that you do not want to lose before doing a clean install though.

You may have damaged system files. After trying everything suggested, check for infection by downloading, installing declining trial versions, updating and running a full scan with Malwarebytes and SUPERAntiSpyware - Downloads - in Safe Mode with networking if necessary.

Once clear of infection, run SFC /SCANNOW Command, report back results.

If none of these help then you can consider a Repair Install.

However if your install varies much from the perfect install compiled in Clean Reinstall Windows 7 then I would strongly suggest you invest the time do do one, because it compiles everything that works best in Win7 based on tens of thousands of installs we've helped with here. So we know then you'll have the best install and keep it that way if you stick with the tools and methods provided there.

So you recommend me doing a Malware-Check, run sfc /scannow and after that a Repair Install with the Win7 CD from my neighbour? And yes, it's Win7 Service Pack 1 too, so it should work.
I will try that tomorrow if possible and post you my results.

Thanks to you both
