"Windows created a temporary paging file" pop up when I start my computer

[System Properties] Windows created a temporary paging file.

I've had this problem for many weeks now, but I haven't been able to solve it.

Here's what I've tried to do so far (original post: here):

1. Click Start, right-click Computer, and select Properties
2. In the left pane, select Advanced system settings
3. On the Advanced tab, click the Settings button under Performance
4. On the Advanced tab, click the Change button under Virtual memory
5. Clear the Automatically manage paging file size for all drives check box and check No paging file
6. Click Set button next to No paging file
7. Click OK on all open windows and restart your machine
8. Open up Windows Explorer
9. Navigate to the root of your system drive (**C:**)
10. Enable the showing of System Files
    1. On the View menu, click Options
    2. On the View tab, clickShow All Files, and then click OK
11. Delete the pagefile.sys file After step 11, hit the Windows Key + R and type in 'Regedit' - This will bring you the the Registry Editor. GO TO - 'Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management'. DELETE EVERYTHING IN THE RIGHT PANEL! Note that you cannot delete '(Default)', or at least I couldn't, so just hit OK or whatever when it says that you can't delete it. Now continue with the rest of the guide above, except instead of leaving the 'No paging file' box check, click on custom paging file size instead. For me, I did 1000 for min and 2000 for max. This is what worked for me. I don't want to fiddle around with these numbers because they worked for me and I don't want to risk having to do this over kek. After clicking on Custom Paging File Size or whatever and you put in the numbers, MAKE SURE TO CLICK SET, AND BE SURE TO CHECK THE 'AUTOMATICALLY MANAGE PAGING FILE SIZE FOR ALL DRIVERS' CHECKBOX - which is located at the top of the window.
12. Click Start, right-click Computer, and select Properties
13. In the left pane, select Advanced system settings
14. On the Advanced tab, click the Settings button under Performance
15. On the Advanced tab, click the Change button under Virtual memory
16. Check the Automatically manage paging file size for all drives checkbox and click OK
17. Restart your machine

I did it twice. The first time I was able to find pagefile.sys in C:. But after doing all the steps I restarted my laptop and the pop up keep showing. A couple of weeks later I did it again, this time I couldn't even find pagefile.sys, even though every time I start my computer I get the "Windows created a temporary paging file..." pop-up

Thanks in advance!
