Answered: Delete your previous version of Windows after an upgrade?

Mon, 18 Sep 2023 01:59:05 +0000

Ten days after you upgrade to Windows, your previous version of Windows will be automatically deleted from your PC. However, if you need to free up drive space, and you’re confident that your files and settings are where you want them to be in Windows, you can safely delete it yourself.

Warning: If it’s been fewer than 10 days since you upgraded to Windows, your previous version of Windows will be listed as a system file you can delete. You can delete it, but keep in mind that you'll be deleting your Windows.old folder, which contains files that give you the option to go back to your previous version of Windows. If you delete your previous version of Windows, this can't be undone (you won't be able to go back to your previous version of Windows).

Press the Windows logo key on your keyboard, then select Settings > System > Storage.

Open Storage Settings
Under your hard drive information, select Temporary files.
Select the Previous version of Windows check box, and then select Remove files.

Answered: How to run Mac Os on Linux?

Macos on Linux

| Oct 3, 2022| Linux MacOS Networking

This shows you all the steps to install a MacOS VM in Linux QEMU using Virtual Machine Manager or virt-manager.

Newer Source, but not as polished: https://github.com/kholia/OSX-KVM Mac KVM Repository: https://github.com/foxlet/macOS-Simple-KVM

Requirements

A modern Linux distribution. E.g. Ubuntu 20.04 LTS 64-bit or later.
QEMU >= 4.2.0
A CPU with Intel VT-x / AMD SVM support is required (grep -e vmx -e svm /proc/cpuinfo)

Installation Preparation

Install QEMU and modify your user using https://christitus.com/vm-setup-in-linux Guide.

Clone this repository on your QEMU system. Files from this repository are used in the following steps.

cd ~
git clone --depth 1 --recursive https://github.com/foxlet/macOS-Simple-KVM
cd macOS-Simple-KVM

Installation Media

This downloads our installation media and I’d recommend using Catalina for compatibility and performance.

./jumpstart.sh --catalina

Note: Modern NVIDIA GPUs are supported on HighSierra but not on later versions of macOS. Recommended PCI Passthrough GPU is 5700XT as this works on Catalina and above. If you go with a 6000 Series Card only certain ones will work on Big Sur and Monterey, but not earlier releases.

Virtual Machine Setup

I recommend using Virtual Machine Manager (virt-manager) as it has a fantastic interface and Simple-KVM does a great job with their setup script. Simply type the following to get the macOS VM setup:

sudo ./make.sh --add

VM Modification

Before we can start out VM we have to have a hard drive to load it. You have two options: physical hard drive passthrough or qcow2 file.

Obviously, the physical drive is considerably faster, but not possible in some instances such as laptops or if you can’t afford a secondary drive.

Physical Hard Drive Passthrough

This is pretty simple as you just click Add Hardware -> Storage and then specify your hard drive.

Note: while you can use drive short names /dev/sda I’d recommend using /dev/disk/by-id/HARDDRIVESERIAL as this doesn’t ever change.

QCOW2 File for Hard Drive

This is even simpler as you just click Add Hardware -> Storage and create new file. Just make sure you put it on at least a SSD or a nvme drive as it will be super slow if you don’t.

Install Process

Boot your machine and select the OS Install Partition on startup.

Use the Disk Utility tool within the macOS installer to partition, and format the virtual disk attached to the macOS VM.

TIP: Using a non-APFS filesystem is recommended.

Go ahead, and install macOS

Post-Installation

Bridge Networking

First find your card interface name

ip a

Example: (Interface name is enp7s0)

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: enp7s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether 24:bb:ee:55:22:33 brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.99/24 brd 10.0.0.255 scope global
    valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
    valid_lft forever preferred_lft forever

Second Update /etc/network/interfaces

source /etc/network/interfaces.d/*
 
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface - old entry
# allow-hotplug enp7s0
# iface enp7s0 inet dhcp

# The primary network interface - new entry
# DEVICENAME = enp7so for this pc and MYUSERNAME need to be $(whoami)
auto br0
iface br0 inet dhcp
  bridge_ports DEVICENAME tap0

auto tap0
iface tap0 inet dhcp
  pre-up tunctl -u MYUSERNAME -t tap0

Lastly Restart the networking service or reboot computer. Then change your VM NIC (Network Hardware) to br0 interface.

sudo systemctl restart networking

Other Considerations

GPU Passthrough (Requires two Graphics Cards) - https://github.com/foxlet/macOS-Simple-KVM/blob/master/docs/guide-passthrough.md
Changing Screen Resolution - https://github.com/foxlet/macOS-Simple-KVM/blob/master/docs/guide-screen-resolution.md
Optimizing System Performance - https://github.com/sickcodes/osx-optimizer
Sound - Two methods, Pass the audio through HDMI if using GPU Passthrough OR Pass through a USB sound card that is macOS compatible
- Note: There is a way to use Voodoo kext or AppleALC, but it will crackle and sound terrible

You can share all the files with any User account on the same PC by keeping the files in the Public Folder.

1. You need to go to This PC then select C drive and click on Users.

2. Open Public Folder.

3. Here you can keep your files, data, applications and it will be accessible by other user accounts as well.

Thu, 24 Nov 2022 05:25:59 +0000

Using the Desktop Menu

Right-click anywhere in the free space present on your desktop. Point to New option from the dialog box.
- This will redirect you to another dialog box. From there, choose the Shortcut option.
Look for a new window asking you to browse the location of the file for which you want to create the shortcut. You must choose the browse option and browse the file location. As soon as you choose the location, the box will be filled itself by the location.
- You can also type the address of the file but it is always better to choose the location as it minimizes the probability of mistakes.
3
Click Next option present somewhere at the right-bottom of the working window.
Type a name for the shortcut. If a Finish button appears at the bottom of the dialog box, click it. If a Next button appears at the bottom of the dialog box, click it, choose the icon you want to use for your shortcut, and then click Finish.

Method2

Using the File Location

Locate the file or application for which you want to create the shortcut.
Right click on that particular file or application for which you want to create the shortcut. Make sure to select the file before right-clicking.
Look for a dialog box. From there, choose the "'Create Shortcut'" option.
- The shortcut is now at the end of the Programs list. For example, if you created a shortcut to Microsoft Word, the program will be present at the end of the list.
Drag the shortcut to the desktop. You can now easily access your application with just a click

Answered: How to Pack a Desktop Computer for Moving?

Desktop Tower

1
Turn the computer off and take the cables out. Shut your computer down first. Then, flip the power switch at the back of your PC (if you have one). Unplug the power cable and set it aside. Next, unplug your keyboard, monitor, ethernet connection, and any other USB connections you may have plugged in to the tower.^[2]^[3]
- Backup any important files before moving. While your computer will probably be fine, you’ll want a backup if the computer gets damaged in the move.^[4]
- Don’t pack the cables in the same box as the PC, as tempting as that may be. Set them aside together to be sorted and packed separately later.
- This process applies to any kind of computer tower. However, if you’re moving a gaming PC, skip down to the last section of the article if you want to take additional steps to keep your investment safe.
2
Reinforce the bottom of a big box with packing tape and clothes. Find a box that’s big enough to hold the tower with a little bit of extra space left over. Flip the box upside down and use packing tape to reinforce the box. Cover each seam multiple times and pull the tape as taut as possible to keep the bottom from falling out. Then, flip the box back over and line the bottom of the box with clean, soft towels or clothes.^[5]
- If you still have the original box the computer came in, use that. Those boxes tend to be pretty strong, even after you’ve torn them open to remove the PC.
- Dust is a computer’s worst enemy. If your box has been sitting out for weeks collecting dust while you’ve been packing, vacuum the inside of the box.^[6]
3
Wrap the tower in a blanket or anti-static bubble wrap. You can wrap a large moving blanket around the computer, or buy some anti-static bubble wrap and wrap that around the tower. Secure the blanket or bubble wrap with packing tape. If you want some additional support, wrap the tower in another layer of fabric and tape it tight.^[7]
- You can use clothing items or towels instead of a moving blanket or anti-static bubble wrap if you prefer. Just don’t use wool, which has a particular affinity for static electricity.
- Do not use regular bubble wrap, which attracts static electricity. Your hard drive and graphics card are especially at risk if your computer is exposed to a lot of static buildup.
4
Set the tower inside of the box right-side up. Carefully lift your tower up and set it in the middle of your cardboard box. Do not pack your computer on its side or upside-down. If you can’t get the tower to rest evenly inside of the box, take it out and move the clothing around at the bottom to even it out.^[8]
- Hold the computer with two hands while you’re lifting it and just go slow here.
- If you’re packing a gaming PC, do not put any pressure on the fiberglass panel. You can shatter this side if you apply too much pressure to it.
5
Fill in the remaining empty space with clothes or packing paper. If there’s any leftover space, fill it in with towels, clothes, packing paper, or foam. This will keep your computer from sliding around in the box or tipping the box over when it’s in transport.
6
Close the box and tape it down before labelling it. Once the empty space inside of the box is filled in, close the top of the box and tape it up. Write “fragile” and “computer” all over the box in large, capital letters. Whether you’re hiring movers or moving on your own, this will keep anyone from accidentally mishandling your computer.
- If your hiring movers, ask them not to put anything on top of your computer. If you’re packing the truck yourself, set the box somewhere secure and don’t set anything down on top of the box.
