Change the Size of the Windows File Protection Cache (Windows 2000/XP)

The Windows File Protection feature of Windows stores copies of common DLL files and replaces them if the original becomes damaged or lost. This tweak lets you control the maximum amount of space available to be consumed by the backup DLL's.

1.Open your registry and find the key below.

2.Create a new DWORD value, or modify the existing value, called "SfcQuota" and set it to the allowable disk space in megabytes (decimal mode). For example, 50Mb would be 0x00000032 (50) and 200Mb would be 0x000000c8 (200). The default value is 0xffffffff (or approximately 300 MB).

Restart Windows for the change to take effect.

Registry Settings
System Key : [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft \Windows NT\CurrentVersion\Winlogon]
Value Name : SfcQuota
Data Type : REG_DWORD (DWORD Value)
Value Data : Size in Megabytes (0xffffffff = default)
