I need to take my desktop into a PC repair shop and leave it for a few days. It would be easy for them to copy the drives without me knowing. I am running Windows 10 with a password but this doesn't actually encrypt the drive. I have multiple SSDs in the PC. I considered just taking the SSDs out but this isn't a good idea because I want them to fix cabling issues (someone told me installing a new power supply is easy but I disagree).

I thought about encrypting sensitive files and encrypting them with Veracrypt but this doesn't seem to be a great idea. I would have to a) find each file, b) encrypt it and then decrypt to use, c) securely wipe the unencrypted file. Is there a better option?
