deleting files in program files directory

[RRADC]

Thanks for reading my post, I'm trying to create script in python that will delete all files in a directory with admin rights for the python script

I do have admin rights for my computer but I can't make adjustments to the C:\Program Files (x86)\Microsoft\ directory.

As of now, every single time I reboot my work computer microsoft keeps changing the default app for http https htm html to edge, so I have to reset it at boot up. Then I have to check the contents of the Microsoft directory delete all the files if it's been re-installed.

I hope to write a script that will delete all the files in C:\Program Files (x86)\Microsoft\ directory and then change the default apps for http https htm html to from edge to chrome.

#import os
#import glob

#files = glob.glob('C:\Program Files (x86)\Microsoft\*')
#for f in files:
#    os.remove(f)
    
import os
import shutil

for root, dirs, files in os.walk('C:\Program Files (x86)\Microsoft'):
    for f in files:
        os.unlink(os.path.join(root, f))
    for d in dirs:
        shutil.rmtree(os.path.join(root, d))

both methods above give me this error

Error:
D:\python>py FFdelete.py
Traceback (most recent call last):
  File "D:\python\FFdelete.py", line 13, in <module>
    os.unlink(os.path.join(root, f))
PermissionError: [WinError 5] Access is denied: 'C:\\Program Files (x86)\\Microsoft\\usb1.spec'

I'm new to python so any help/guidance would be helpful, thanks
