System restore not working & unable to create system restore points, error code 0x800423of

Complete novice when it comes to pc tech stuff, so please bear with me
Some basic info : OS : Windows Vista Ultimate Service Pack 2, 32 bit PC : Dell Inspiron 1545

System Resore has not been working for a couple of months now, don't know exact date it "broke" so unable to pin point what may have "broken" it. Have done several disc checks & sfc/scannow. As heading of this post says,when I try to manually create a restore point I get error code 0x8004230f. Restore points are not being created automatically by the system either. Please can anyone help & advise (in laymans terms)? Thanks all.

 

It appears that the issue is created by conflicting software or similar problems which also deletes all previous restore points.
Have you tried booting to Safe Mode to check if there are still errors trying to use System Restore?

 

Hello Dee,

I see that you have already tried SFC scan. Assuming that it was successful, the issue seems to be either caused by a 3rd party security software to corrupt OS files.
If you have any 3rd party security software installed (example: Norton, McAfee etc) try uninstalling the same and check if you are able to create a new restore point. If that does not fix the issue, you can try repair / inplace upgrade. This would essentially repair corrupted OS files.
To perform a repair / inplace installation of Windows Vista follow these steps:

Close all the running applications.
Insert the Windows Vista DVD in the computer's DVD drive.
In the Setup window, click Install Now.
Note: If Windows does not automatically detect the DVD, follow these steps:
Click Start, and then type Drive:\setup.exe in the Start Search box.
Note The Drive placeholder is the drive letter of the computer's DVD drive.
In the Programs list, click Setup.exe.
In the Setup window, click Install Now.
Click Go online to obtain the latest updates for installation (recommended).
Type the CD key if you are prompted to do this.
Select the operating system in "Install Windows" page you want to Upgrade or Inplace.
Click Yes to accept the Microsoft Software License Terms.
On the Which type of installation do you want? screen, click Upgrade.
When the installation is complete, restart your computer.

If this does not fix the issue, you may have to back up the data and reinstall Windows.
