Windows 8.1 64bit repair without reinstall? Try this!
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:
- Dism /Online /Cleanup-Image /CheckHealth
- Dism /Online /Cleanup-Image /ScanHealth
- Dism /Online /Cleanup-Image /StartComponentCleanup
- Dism /Online /Cleanup-Image /RestoreHealth
- "now restart"
- 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).
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!
