The Set percentage of disk space used for client computer cache machine setting should be configured correctly. This policy setting changes the default percentage of total disk space to dedicate to caching retrieved content with BranchCache. This content is made available to other requesting client computers if they are authorized by the server to access the content. If you enable this policy setting, you can configure the percentage of total disk space to allocate for the cache. If you disable or do not configure this policy setting, the cache is set to 5 percent of the total disk space on the client computer. Fix: (1) GPO: Computer Configuration\Administrative Templates\Network\BranchCache\Set percentage of disk space used for client computer cache (2) KEY: HKLM\SOFTWARE\Policies\Microsoft\PeerDist\CacheMgr\Republication\SizePercent
