I need to share my personal Windows 11 laptop with peers for basic tasks (web browsing, MS Word, light coding). I have created a Standard User account, but I am struggling with two specific requirements:
-
Privacy: I want to completely block this user from accessing my
D:drive and specific folders onC:. I tried denying access to “Authenticated Users,” but this locked my Administrator account out as well. -
Storage Limitation: I want to limit this user to exactly 10GB of space on the SSD so they don’t clutter my drive.
Is there a way to use NTFS permissions to target only this specific user without affecting my own access, and what is the best way to enforce a hard storage limit for them?
I followed this step ,
-
Right-click your D: Drive -> Properties -> Security tab.
-
Click Edit, then click Add.
-
Type the name of the Guest account you created and click OK.
-
Highlight that Guest user in the list and check the Deny box for “Full Control”.
-
Click Apply. Windows will warn you about Deny entries; click Yes.
-
Result: You (Admin) still have access because you aren’t that specific user, but they are hard-blocked.
but it didn’t show the user added here
