I’ll try this right after I finish my homework and if I have some free time today.
Step 0: Disconnect all network connections. Step 1: Shut down the computer and remove the hard disk. Step 2: Insert a new hard drive and perform a fresh Windows installation. Step 3: Update the antivirus software to the latest version, then scan and clean the existing drive. Ideally mount it as a secondary drive in a USB enclosure so you can connect it once the system starts. If not, you may need to hotplug it carefully—only if you're very experienced. Both SATA and PCIe support hotplugging, but I strongly advise against it unless you have alternatives like an external USB enclosure. In any case, this is the only method that works reliably if you don’t want to attempt restoring the old disk’s operating system. If you wish to recover the previous drive, you’ll need a bootable recovery tool and run it instead. Detailing that process would be quite complex and risky, potentially damaging files or erasing the OS entirely.
I haven't reviewed your earlier discussion, but have you considered verifying your admin settings? Besides that, I notice Windows often reports problems deleting files due to missing admin privileges. In reality, it's usually because a file is open and blocking access. This isn't uncommon—your issue might stem from a virus, especially since I haven't encountered that exact warning. If the system file is the root cause, a scan might help.
Another point: sometimes I encounter issues with startup entries in CCleaner or the Windows Task Scheduler. These can interfere with normal operations. Checking your auto-start options and ensuring no hidden or obscure entries exist could resolve the matter.
Occasionally, when installing questionable apps, rogue startup records appear in Task Scheduler. They might run files from unusual locations, making them hard to locate. Clearing these could restore normal function.
If you spot any suspicious entries, remove them or investigate further online. For persistent problems, a clean install via the advanced boot menu might be necessary.
If you need more help, consider using a factory image or a clean installation to eliminate lingering issues.
