System File Checker

open elevated command prompt

DISM.exe /Online /Cleanup-image /Restorehealth

When DISM completes run system file checker

sfc /scannow

When it completes it will either tell you no errors were found or some errors were found and fixed.

If it tells you there were some files that could not be fixed go to the log and down the bottom it should have a list of exactly which files.

C:\Windows\Logs\CBS\CBS.log

I’ve seen at least one case where i had to use attrib command to remove protected and system file protection flags so i could delete and replace a corrupt system file that was 0 bytes in size and system file checker couldn’t resolve it, no idea how the customer ran into that situation, brand new hardware that was perfectly fine.

If you need to hand replace a single file use the attirb command to set the flags back again.

GodMode

Symbolic links

Remap a folder that has to be on C drive to another Drive with more free space.

Example: itunes by default only saves backups of iphones and ipads etc. to C: under the user profile folder there is no way to change that.
Delete or rename the old backup folder.
open elevated command prompt.
change directory to the folder where the apple backup folder is
C:\users\"username"\Apple\Mobilesync\
At command prompt it probably opens in the user profile anyway so you just need to type CD Apple\Mobilesync\
mklink /d Backup "[desired-new-backup-path]"
I made the desired new location D:\Backup
This creates a symbolic link in the folder C:\users\user\apple\mobilesync\ That looks like a folder called Backup even when you open it it looks like it's a folder on C: But it's really remapped to D:\Backup where we have enough free space.
