This will restart your computer and disable the feature. Check the booting time the next time you start up your system.


Fix 4 – Adjust the paging file size

The paging file size or the virtual ram can make your computer faster. But, in some cases, it may slow boot the system.

1. At first, open the Run window.

8. Now, you will see two distinct options of paging file size. Like – ‘Recommended‘ and ‘Currently allocated‘. If you see ‘Currently allocated‘ size > ‘Recommened‘ size, you have to take control of the paging size.

9. Just, uncheck the option “Automatically manage paging file size for all drives” so you can adjust it manually.

10. Then, choose the ‘C:‘ drive from the list.

11. Next, click on “Custom size:” to select it.


Custom Size Min


12. Set the values of size using these formulae ~

Initial size (MB)= Recommonded Size 
Maximum Size (MB)= 3*(1024* Amount of Physical RAM)

[Example – Initial Size of the RAM should be equivalent to the same amount of ‘Recommended:’ size. In our case, it will be  –

Initial size (MB) = 2938

In our case, this system has 16 GB of RAM or 16*1024=16384 MB. So, the ‘Maximum Size(MB)’ will be –

Maximum Size (MB) = 3*(1024*16) = 3* 16384 = 49152

13. Once you are done, Don’t forget to click on “OK” to save the settings.


Maximum Size Ok Min


This way, you can uplift the slow booting process by adjusting the paged file settings.


Fix 5 – Run SFC scan

You can run the SFC scans to check if there are any system files issues.

1. At first, press the Windows key+R keys together.

2. In the Run window, type “cmd” and then hit Ctrl+Shift+Enter keys together.



2. Simply, paste this code in the terminal and hit Enter to run the scan.

sfc /scannow


Sfc Scannow


Wait for a while to finish the process.

3. For the second scan, execute this command in the terminal.

DISM.exe /Online /Cleanup-image /Restorehealth


Dism Restorehealth


This scan will also take some more time.

Once you are finished, close the Command Prompt window.

The best way to get a fresh PC experience is to refresh the computer.

1. At first, press the Windows key+I keys together.

2. Then, tap on “System” on the left-hand.

Follow the on-screen process further to complete the reset process.

The booting time will be much faster than before once your device is reset.

Bonus Tips

1. The best way to fix a slow booting issue on your system is the use of SSDs. Just buy a 128 GB (at least) SSD, plug it in and move port your Windows OS from your HDD to SDD. This will decrease the booting time significantly.

2. Do not install any external app in the same drive where Windows is installed. Try to keep at least 30 GB of free space in the C: drive.
