Step 1: Free Up Space

Remove thumbs.db from everywhere-

dir /s /b "%SYSTEMDRIVE%\" | find /I "thumbs.db"> thumbs.txt & for /F "usebackq tokens=*" %%A in (thumbs.txt) do if exist %%A del /Q "%%A"


Clear browser cache(chrome) and flush DNS-

ipconfig /flushdns

"%USERPROFILE%\AppData\Local\Google\Chrome\User Data\Default\Application Cache\."

del /S /Q "%USERPROFILE%\AppData\Local\Google\Chrome\User Data\Default\Cache\."

del /S /Q "%USERPROFILE%\AppData\Local\Google\Chrome\User Data\Default\Media Cache\."

del /S /Q "%USERPROFILE%\AppData\Local\Google\Chrome\User Data\Default\GPUCache\."

rundll32.exe InetCpl.cpl,ClearMyTracksByProcess 8


Remove microsoft cache-

del /S /Q "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\IconCacheToDelete\."


Clear logs and error reports-

dir /S /b "%userprofile%\AppData">> tmp.txt
for /F "usebackq tokens=*" %%A in (findstr /E ".log" tmp.txt) do if exist "%%A" del /S /Q "%%A"

for /F "usebackq tokens=*" %%A in (findstr /E ".old" tmp.txt) do if exist "%%A" del /S /Q "%%A"

del /S /Q "C:\ProgramData\Microsoft\Windows\WER\ReportArchive\."

del /S /Q "C:\ProgramData\Microsoft\Windows\WER\ReportQueue\."


Clear temporary files folder-

dir /s /b "%tmp%"> tmp.txt
for /F "usebackq tokens=*" %%A in (tmp.txt) do (

del /Q "%%A"

rmdir /S /Q "%%A"


if exist tmp.txt del /q tmp.txt

Step 2: Free Up Memory(RAM)

Disable auto enabled task-

schtasks /change /tn GoogleUpdateTaskMachineUA /DISABLE
schtasks /change /tn GoogleUpdateTaskMachineCore /DISABLE

schtasks /change /tn MapsUpdateTask /DISABLE


Disable high ram consuming task-

Taskkill /F /IM SearchUI.exe
Taskkill /F /IM OneDrive.exe

Taskkill /F /IM SystemSettings.exe

Taskkill /F /IM WinStore.Mobile.exe

Taskkill /F /IM igfxTray.exe

Taskkill /F /IM igfxTray.exe

Taskkill /F /IM uTorrent.exe

Taskkill /F /IM SkypeHost.exe

Taskkill /F /IM spoolsv.exe

Taskkill /F /IM SearchIndexer.exe


Disable microsoft update seeing(ram and internet data consuming)-

powershell mkdir -Force "HKLM:\SOFTWARE\Policies\Microsoft\Windows\DeliveryOptimization"
powershell sp "HKLM:\SOFTWARE\Policies\Microsoft\Windows\DeliveryOptimization" "DODownloadMode" 0

Step 3: Other Things to Help Performance

Empty recyclebin-

rmdir /S /Q "%systemdrive%\$Recycle.bin\." & mkdir "%systemdrive%\$Recycle.bin"


Clear crash dumps-

rmdir /S /Q "%userprofile%\AppData\Local\CrashDumps" & mkdir "%userprofile%\AppData\Local\CrashDumps"


Delete windows demo files(useless with activated windows-

del /S /Q "C:\ProgramData\Microsoft\Windows\RetailDemo\."
rmdir /S /Q "C:\ProgramData\Microsoft\Windows\RetailDemo\."

Step 4: Optimize Booting Time and Performance

Defragment your system drive-

defrag %SystemDrive% /U /V


Reduce boot delay-

"C:\Windows\System32\bcdedit.exe" /timeout 3


Defragment boot partition-

defrag -b %SystemDrive%

Step 5: See the Difference

To check your free physical memory-

wmic os get freephysicalmemory /format:value | find "FreePhysicalMemory"


To check your hard disk free space-

fsutil volume diskfree c: | find "Total # of free bytes">tmp.txt
FOR /f "tokens=7 delims= " %%A in (tmp.txt) do (

set MEMORY=%%A


echo %MEMORY%
