Windows breaks after every repair install

Not too long after each Windows repair install I do, I have the same problem again. A month or two after repair, some programs lose the ability to reinstall.

For example: I recently uninstalled Soluto and Avast Antivirus, and now neither is installable anymore. Both programs claim that they don't have write access. I haven't messed with Windows settings or done anything unusual. Also, Dwrite.dll, PresentationBuildTasks.dll and console.dll.mui are corrupted and cannot be replaced by sfc /scannow because the original files are supposedly incorrect as well.

What should I do? My personal suspicion: my hard drive might be dying.

Work through these Troubleshooting Steps for Windows 7 starting with testing your HD.

If you have questions about the integrity of your Win7 install (as I would) then you can follow these steps to get a perfect Clean Reinstall - Factory OEM Windows 7 which are the same for retail.

I'm currently running a veryify/write/verify bad sector scan/repair with HDAT2 on the hard drive. I've already done almost everything in the guide you linked. I'll try what's left in it (probably mostly irrelevant in my case, but might as well.) I haven't run Samsung's disk check yet, so that's probably the last relevant step. (chkdsk found no errors, after I finally got it to work from the recovery console. It refused to scan for quite a while. I can't remember why.)

Anyway, if I don't spot a fix in any of that, I'll try a clean Windows 7 reinstall, as you suggested.

At that point, if the problems remain but the hard drive seems healthy, is there something else that could be the cause?

Britton: I can't understand you. How does rebooting start a repair install?

Also, my machine doesn't have bloat. I built it myself, and I keep its software fairly minimal.

Ah. I've run SFC /scannow about 8-10 times from the recovery console and it can never replace the files I described because it says it doesn't have good copies of the files to replace with.

Well the next step after unfixable System files are confirmed is to run the Repair Install, but since that is not working for you I'd do the Clean Reinstall making sure to follow the Best Practices with drivers and everything else so you know you have a perfect install.

I'd also wipe the HD first with Diskpart Clean Command to clear the boot sector of possible corruption we've seen manifest itself if many strange ways.

Once you've done this if problems persist you'll know its hardware, however installer failures are rarely hardware related that I've seen.

Alright, after a lot of testing in various boot programs by way of Hirens, including the one made by my hard drive brand, I'm convinced the disk is fine. I'll try reinstalling Windows in a few days. Hopefully I'll remember to update here. Thanks!

I'm finally almost at the point at which I will erase my hard drive and reinstall windows. Is there anything faster than the diskpart clean command for zeroing the hard drive? I have a hirens disk with a lot of different bootable disk management programs on it.
