Most memory guides send you through four Windows screens. In Turbo PC Optimizer, you can see used RAM against the total, programs that load at sign-in and services running in the background.

• Click Optimize now in Memory optimization to trim background processes' working sets. Their pages move to standby or the page file, making RAM available without closing programs.
• Turn on auto mode if one heavy app keeps taking memory from the rest. Trims repeat every 5, 10, 30 or 60 minutes, with 10 as the default.
• Switch off startup items and services you never use.
• Click Boost to the max before a game or a long render. It suspends windowless background processes and frees their memory. Click again to restore them. This mode also powers our game optimizer software.

The trim skips Windows core processes, the shell and other users' sessions. System tweaks get a restore point before they apply.

In Task Manager, open Performance > Memory. In use is what apps hold, including compressed pages. Available includes the standby cache and is ready for Windows to hand out. Committed shows memory promised to apps against a limit equal to RAM plus the page file. Cached is standby data kept for faster launches.

A Yahoo Tech explainer on Task Manager readings says high standby and compressed memory are fine while the system stays responsive; repeatedly reaching the commit limit means a shortage. On Microsoft's Q&A forum, users ask why the bar shows 86% of 32 GB while the Users tab lists about 7 GB. The gap is cache, compressed pages and driver memory that no listed process owns.

• Available near zero with Committed close to its limit means a shortage. Close heavy apps and plan a RAM upgrade.
• One process far above the rest when sorted by Memory points to that app. Close it or restart it.
• A large Cached figure with healthy Available needs nothing.
• Usage that climbs over days and drops after a restart suggests a leak. Restart weekly and update the growing app or driver.
• Usage that stays high after a clean restart calls for RAMMap and a malware scan.

Microsoft's performance tips for Windows say startup apps can slow boot time and increase background usage. On the Startup page, begin with apps whose impact label is High.

Keep security software and your touchpad and audio utilities. You can safely switch off updaters, chat clients and cloud sync apps you launch by hand. Fewer programs competing for the disk at sign-in also make Windows startup faster.

One user who had not restarted in weeks reported a ten-gigabyte drop after a reboot. That extreme case shows what can accumulate when you only shut down with fast startup and never restart.
Some owners report 15-20 GB in use with everything closed immediately after a restart. This usually means a driver holds memory that no process owns. Install pending Windows and driver updates, then check Microsoft's RAMMap utility. Its Use Counts tab lists driver-locked pages separately from Active and Standby memory.

In Chrome, open Settings > Performance and turn on Memory Saver. In Edge, turn on sleeping tabs under Settings > System and performance. Both free memory from inactive tabs and reload them when you click back.

Press Shift+Esc in Chrome or Edge to open the browser's task manager. It shows memory use for each tab and extension, which Windows Task Manager does not separate. A forgotten extension can hold hundreds of megabytes.
Teams, Discord and other apps built on a browser engine behave like extra browsers. In an admin thread about idle 16 GB office PCs stuck at 80%, a commenter reported getting 1-2 GB back by closing Teams alone. Efficiency mode in Windows 11 Task Manager lowers app priority and saves some CPU, but leaves memory with the app.

Microsoft's performance team calls standby pages cache, and its documentation treats a large Cached figure as healthy. Yet one owner of a 32 GB laptop reported an almost immediate speedup after emptying the standby list in RAMMap. The gain faded in a couple of hours as Windows refilled the cache.

Run RAMMap as administrator and choose Empty > Empty Standby List. Optimize now in Turbo PC Optimizer also empties the standby list during each trim. On a 16 GB or 32 GB PC with plenty Available, expect only a smaller number on the graph.

Cleaners call the Windows EmptyWorkingSet function to force running apps' working memory out to the page file, as How-To Geek's explainer on memory optimizers describes. If an app needs pages that have left RAM, Windows reads them back from disk. Microsoft's working set documentation calls this a hard page fault, resolved by reading from the page's backing store. Empty RAM alone adds no speed.

Turbo PC Optimizer uses the same call. Its auto mode runs no more often than every 5 minutes.
A trim can help on an 8 GB laptop with a browser and a meeting app open, just before you start a game or an export.

Open Settings > System > About > Advanced system settings > Performance Settings > Advanced > Virtual memory Change. Keep Automatically manage paging file size for all drives ticked.

A larger page file raises the commit limit so heavy apps can open, but adds no speed. It also needs room to grow: Geek Rewind's Windows 11 RAM guide suggests keeping 10-15% of the drive free and notes that clearing junk files does not free RAM directly.

Search results mix the two because phones call storage "memory". Turbo PC Optimizer frees RAM and leaves your files alone. Its disk analyzer only shows what takes up space.
If RAM looks fine on the Memory page but your PC is slow, use the disk, CPU and update checks in why your computer runs slowly.

Open Windows Security > Virus & threat protection > Scan options, select Full scan and click Scan now. In Task Manager, look for an unfamiliar process that keeps growing. Right-click it and choose Open file location. A file in a random folder under AppData deserves a closer look. Sort Settings > Apps > Installed apps by install date and remove anything you did not install yourself.
