What is Wise Memory Optimizer?
Wise Memory Optimizer displays memory usage and provides controls for freeing RAM, emptying standby memory and defragmenting memory. Its memory chart gives a quick overview before you choose an operation. Automatic optimization can run when available memory falls below a chosen threshold, with an option to wait until the CPU is idle.
This entry links to the publisher’s Windows setup package. WiseCleaner also describes a portable edition, but it is not the download selected here. The publisher lists support for 32-bit and 64-bit Windows, including Windows 10 and 11.
Memory cleanup is not a guaranteed performance improvement: effectiveness varies with the hardware, and no speedup was measured for this entry. The publisher also warns that Defrag RAM takes longer than a normal cleanup and temporarily raises in-use memory before releasing it. The gallery image illustrates the application’s memory chart and automatic-optimization settings; it is not a verified capture of the linked release.
