Answer
1. run elevated command prompt (cmd with administrator rights): type
Dism.exe /online /Cleanup-Image /StartComponentCleanup
Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase
freed about 100-200Mb
2. delete files in %SystemDrive%WindowsSoftwareDistributionDownload
freed 1-2 Gbs
3. run elevated command prompt (cmd with administrator rights): and type:
TAKEOWN /F "C:WindowsSystem32DriverStoreFileRepository" /R
ICACLS "C:WindowsSystem32DriverStoreFileRepository" /T /L /GRANT
*S-1-1-0:F
RD /s /Q "C:WindowsSystem32DriverStoreFileRepository"
freed many Gbs!
It should help - run at your own risk
英文不好的，打开cmd （管理员）运行下面命令就好了：
Dism.exe /online /Cleanup-Image /StartComponentCleanup
Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase
TAKEOWN /F "C:WindowsSystem32DriverStoreFileRepository" /R
ICACLS "C:WindowsSystem32DriverStoreFileRepository" /T /L /GRANT *S-1-1-0:F
RD /s /Q "C:WindowsSystem32DriverStoreFileRepository"
