Repair Windows 8 / 8.1 with simple command

To Run the SFC /SCANNOW Command at Boot

1. Open a command prompt at boot.

2. In the command prompt, type diskpart and press Enter, then type list volume and press Enter. (see screenshot below)

3. Make note of the drive letters for your boot drive (ex: 350MB "System Reserved" partition) andWindows 8 drive, then type Exit and press Enter. (see screenshot above)
NOTE: If you do not have a "System Reserved" partition, and are not multi-booting with another operating system, then the boot drive and Windows 8 drive may be the same drive letter.

4. In the command prompt, type the command below and press Enter. (see screenshot below)
NOTE: You will see a blinking cursor at the prompt until finished. This will take a while to finish running though.

sfc /scannow /offbootdir=C:\ /offwindir=D:\windows

   Note

You will need to substitute the drive letter of the partition/volume where your system boot files are stored in the offbootdir=C: part of the command above instead.

You will need to substitute the drive letter of your Windows 8 partition/volume in the offwindir=D:part of the command above instead.

5. When the scan is complete, hopefully you will see an all is ok message like below.

6. Close the command prompt, and restart the computer to start Windows 8.

   Note

If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command 3 times restarting the PC after each time to completely fix everything that it's able to.

If not, then run the Dism /Online /Cleanup-Image /RestoreHealth command to repair any component store corruption, restart the PC afterwards, and try the sfc /scannow command again.

If still not, then you could do a refresh of Windows 8, or run a System Restore using a restore point dated before the bad system file occured to fix it. You may need to repeat doing a System Restore until you find a older restore point that may work.

If still not, then you can use the steps in the TIP box in the OPTION THREE section below to manually replace the files that SFC could not fix.

 OPTION THREE 

How to See and Read Only the "SFC" Scan Results from the CBS.LOG

NOTE: When SFC runs, it logs it's actions into the C:\Windows\Logs\CBS\CBS.log. The steps in this option will show you how to see only the specific SFC entries with the [SR] tags in this CBS.log. This can be helpful to show you what files SFC could not fix automatically if you wanted to try and manually replace them.

1. Open an elevated command prompt or elevated PowerShell.


2. In the elevated command prompt or PowerShell, copy and paste the command below and pressEnter.
NOTE: This will place a sfcdetails.txt file on your desktop with only the SFC scan result details from the CBS.LOG in it.

Code:

findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >%userprofile%\Desktop\sfcdetails.txt

3. Close the elevated command prompt.

4. Open the sfcdetails.txt file on your desktop to see the SFC scan details in the CBS.LOG.

5. When finished, you can safely delete the sfcdetails.txt file afterwards if you like.

   Tip

If you need to replace a corrupted system file that SFC cannot fix, then this will show you how to:

If you have to many files that are corrupted, then run the Dism /Online /Cleanup-Image /RestoreHealth command to repair any component store corruption, restart the PC afterwards, and try the sfc /scannow command again.

If you only have a few, then you could manually extract a new copy directly from your Windows 8 installation DVD or USB thumb drive, or ISO file if in a virtual machine.

Fix: Windows Updates fail to install in Windows 7 | 8

Sometimes, some Windows Updates fail to install, and just refuse to get installed on your computer even when you try a couple of times. If you face this problem where Windows Updates will not install, this tutorial will help you identify and troubleshoot the problem. Do create a system restore point first. You may then try any of these, in no particular order.

Windows Updates Fail To Install

1. If you are unable to install Windows Updates, first clear up your Temporary Files and Internet Cache, reboot and try again. See if this helps resolve the issue. Best and easy to use the built-in Disk Cleanup utility or CCleaner.

2. Disable your Firewall and Anti-virus software and try again.

3. As mentioned earlier, many a times, an update may fail to install in the first instance, but for some inexplicable reason, succeeds in the 2nd or 3rd try. So try a couple of times.

4. Search on Microsoft, for the patch using the Update KB number, and download its stand-alone installer. Now apply the patch manually. Search for just the number; don’t include KB ! Also, go here to see the Complete Master List of Windows Update Error Codes.

5. Use the Windows Update Troubleshooter from Microsoft. It resets Windows Updates settings to defaults.

6. Use our Fix WU tool and see if it helps. It re-registers all the dll, ocx and ax files required for the proper functioning of Windows Updates.

7. Run System Update Readiness Tool. It can help fix problems that might prevent Windows Updates and Service Packs from installing.

8. Right-click Computer > Manage > Services > Stop the “Cryptographic Service” and rename the “Catroot2″ folder situated in C:\Windows\System32\Catroot to something else like say Catroot2X.

Reboot.

Now run the update or the installers again. This action will re-generate a new Catroot2 folder and the updates or hotfixes, should hopefully install.

9. If still you have a problem then, go to C:\Windows\WindowsUpdate.log and look for the most recent entry. This will be present towards the end of the log. Any failed updates will have error code/s written next to them. Note them down. If you find just too many entries too confusing delete this WindowsUpdate.log and try installing the problematic updates again.

Now open the newly re-created WindowsUpdate log file and have a look at its contents.

The warnings will probably appear as -: WARNING: Failed to find updates with error code XXXXXXXX.

Now Right-click Computer > Manage > Event Viewer > Applications and Service Logs > Microsoft > Windows > WindowsUpdateClient > Operational . Check out for any Critical Message or Warning.

Next refer the Windows Update Error Codes . This will give you the direction in which you may have to look for the solution.

11. Flush the Software Distribution Folder. Run Command Prompt as administrator. In the CMD box that appears on the computer screen, enter the following strings of text, one at a time, and hit Enter.

net stop wuauserv

net stop bits

Now browse to the C:\Windows\SoftwareDistribution folder and delete all the files and folders inside.

If the files are in use, restart your device. After rebooting, run the commands above again. Your Windows Store App needs to be closed by the way, so do not start it.

Now you will be able to delete the files from the mentioned Software Distribution folder. Now in the Command Prompt windows, type the following commands one at a time, and hit Enter:

net start wuauserv

net start bits

Reboot. If you are using Windows Update try using Microsoft Updates or vice versa.

11. Read this, if Windows Update is not working or the Windows Update page itself is blank.
