Increasing the App-V cache size with a script:

For anyone out there that wishes to increase the App-V cache beyond 10gb, this will be handy info.

Well for starters, the size of the cache is dictated by a reg key in HKEY_LOCAL_MACHINESOFTWAREMicrosoftSoftGrid4.5ClientAppFS called FileSize, useless information unfortunately as changing this key makes no difference after a restart. So i did a bit of googling and found a tool called cachesizetool which boasted to do exactly what I wanted, after a quick glance at the readme I tested the command and I get stuck with a big dirty EULA prompting me to accept it… I saw this before with Pstools after they were purchased by microsoft but at least they had the decency to include a /accepteula switch, but with this tool there is no such option.

So it raises the question really, why bother your arse writing a command line tool then force the user to accept an eula? It’s mind blowing how stupid this is really. It’s like putting petrol in the car then getting the bus…

anyway to cut a long story short, accepting the eula creates a reg key, and this key can be forced in before running the command to ensure you dont get prompted…
