Configuring the Registry Size Limit (Windows NT/2000/XP) Popular

The Registry Size Limit, or RSL, controls the total amount of space the may be consumed in paged pool memory and disk space by registry data. The RSL is a kind of "global quota" for registry space.

This tweak can be easily applied using WinGuides Tweak Manager. Download a free trial now!

Open your registry and find the key below.

Create new DWORD value, or modify the existing value, named 'RegistrySizeLimit' and set the value to equal the desired RSL in bytes.

RegistrySizeLimit must have a type of REG_DWORD, and a data length of 4 bytes, or it is ignored. If you set the value RegistrySizeLimit to less than 4 megabytes (MB), it is forced up to 4 MB. If you set it to greater than about 80 percent of the size of paged pool, it is set down to 80 percent of the size of paged pool (it is assumed that paged pool is always more than 5 MB). If you set it to 0xffffffff the maximum size allowable (or 80 percent of paged pool, up to 102 MB) is set.

Shutdown and restart Windows for the change to take effect.

		(Default)	REG_SZ	(value not set)
		RegistrySizeLimit	REG_DWORD	0xffffffff (4294967295)

	HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control
