Clearing Windows Update Cache

Clearing Windows update cache is used when some updates will not complete. This could help Windows to update automatically.

Open administrator command prompt:

Windows key + R, type “cmd” into the box, ctrl + shift + enter
These steps will stop the update services, type them line by line into the command prompt:
```
 net stop wuauserv
 net stop cryptSvc
 net stop bits
 net stop msiserver
```

Now we have to remove the updated cache:

 ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
 ren C:\Windows\System32\catroot2 catroot2.old

Now we must restart the update services:

 net start wuauserv
 net start cryptSvc
 net start bits
 net start msiserver
