Windows 8.1 / 10 64bit repair without reinstall? Try this!

Update 16.10.2019:

Since the cloning from a Sata M.2 128 GB to a 480 GB SSD, some bluescreen returns, mostly with the win32kfull.sys . Maybe the main problem was, some files are getting a second identical ownership. CBS Log informations tells it.


Update 22.05.2017:

Don`t waste your time on Win 8, switch to Win 10. Since I was, I`m happy again (with the same laptop)! Good Luck!


Windowsbutton+X -> choose Prompt (Administrator)
After that, the console should have opened in Administrator mode with the following content:


Individually paste the following commands and confirm it with Enter:

  1. Dism /Online /Cleanup-Image /CheckHealth
  2. Dism /Online /Cleanup-Image /ScanHealth
  3. Dism /Online /Cleanup-Image /StartComponentCleanup
  4. Dism /Online /Cleanup-Image /RestoreHealth
  5. "now restart"
  6. sfc /scannow

Most importantly, the PC / laptop must have a stable Internet connection. These commands repair the registry, the data integrity of the hard disk and the file system as well as important Windows DLLs (if necessary through Windows Update, which is why you need the internet connection).

You can find out exactly what the individual repairs resulted from under C:\Windows\Logs\CBS in the log. At the bottom is always the latest entry. Wait until the repair is finished so that you can read the complete log. Open in between and read along (without saving) works too.

The sfc / scannow command does sometimes (due to responses from Microsoft employees) up to three attempts to correct any errors.

Result: After I had corrupt DLLs in my Windows 8.1, most likely caused by an update, I had to read through many postings. Often I read this as a problem-solving: "New Installation".

Anyone can logically and clearly recognize that a clean installation on a undeserved "Update - phenomenon" can not be "the solution". For this we need then reinstall the OS every 14 days, due to the repeated failures of Windows Update? Just stupid. Mainly for these honest people seeking help I wrote this post. I hope he is written easy to understand. If you like it, share it!
